McKinsey & Co Diamond Industry Report

Published

on

This report by McKinsey explores the challenges and opportunities facing the diamond industry in the wake of several significant shifts. Here’s a breakdown of the key points:

Market Downturn:

  • Diamond prices have plummeted after a surge during the pandemic.
  • This is due to a combination of factors, including:
    • Increased supply chain normalcy.
    • Reemergence of traditional engagement timelines.
    • Rise of lab-grown diamonds (LGDs) as a more affordable alternative.
    • Growing consumer demand for ethical and sustainable sourcing (ESG).
    • Sanctions on Russia, a major diamond producer.

Shifting Consumer Preferences:

  • Younger generations (Gen Z) are driving changes in diamond buying habits:
    • More frequent purchases for self-reward.
    • Preference for ethical sourcing and sustainability.
    • Increased online shopping for jewelry.
    • Growing interest in LGDs and recycled diamonds.

The Rise of Lab-Grown Diamonds:

  • LGDs pose a major challenge to natural diamonds due to:
    • Lower cost (up to 80% discount).
    • Perceived ethical and environmental advantages.
    • Increasing quality and size availability.

The Future of the Industry:

  • The industry needs to adapt to survive:
    • Natural diamond producers can:
      • Invest in traceability and ESG practices.
      • Highlight the unique value proposition of natural diamonds (rarity).
      • Consider vertical integration to manage costs and ensure compliance.
    • LGD producers can:
      • Focus on further price reduction and technological advancements.
      • Address potential environmental limitations of LGD production.
    • All diamond players can:
      • Develop innovative marketing strategies.
      • Embrace digital technologies for transparency and efficiency.
      • Build stronger partnerships for financing and branding.

Uncertainties Remain:

  • The long-term impact of LGDs on the diamond market is unclear.
  • Questions remain about diamond price volatility and ownership of the value chain.

Conclusion:

The diamond industry is at a crossroads. Adapting to changing consumer preferences, embracing technology, and addressing ethical concerns will be crucial for companies to ensure stability and longevity in the years to come.

The Diamond Industry: Navigating a Market in Transition

Insights from Changing Consumer Behavior, Technological Advancements, and ESG Imperatives

The global diamond industry, long associated with timeless luxury and tradition, is undergoing a seismic transformation. Once characterized by stability and predictable growth patterns, it now faces significant disruptions fueled by shifting consumer behavior, technological advancements, and heightened environmental, social, and governance (ESG) expectations. This article examines these trends, highlighting how diamond producers—both natural and lab-grown—can position themselves for sustained relevance and profitability.


A Market Recalibrated Post-Pandemic

The diamond industry experienced an unprecedented surge in prices during the COVID-19 pandemic, driven by delayed engagements, disrupted supply chains, and an increase in discretionary spending on luxury goods. However, this trend has reversed sharply, with diamond prices now at multi-year lows.

Several factors have contributed to this decline:

  • Rise of Lab-Grown Diamonds (LGDs): Offering affordability and perceived ethical benefits, LGDs have captured a growing share of the market.
  • Return to Pre-Pandemic Norms: Engagement and marriage cycles have resumed their traditional rhythms, reducing the urgency of purchases.
  • Sanctions on Russian Diamonds: Restrictions on Russian producers, including Alrosa, have altered global supply dynamics.
  • Increased ESG Awareness: Consumers now demand greater transparency and sustainability in diamond sourcing, putting pressure on traditional producers to innovate.

Shifting Consumer Preferences: A Generational Shift

Consumer behavior, particularly among younger generations, is reshaping the diamond market. Key trends include:

  1. Ethical Sourcing and Sustainability:
    Generation Z and Millennials prioritize brands that align with their values. Ethical labor practices, sustainable sourcing, and carbon-neutral operations are non-negotiable for these consumers.
  2. Increased E-Commerce Activity:
    Online diamond purchases are growing, with projections suggesting that nearly 20% of fine jewelry sales will occur digitally by 2025. The convenience and transparency of online platforms are redefining how consumers engage with brands.
  3. Lab-Grown Diamonds as an Alternative:
    LGDs are no longer confined to industrial use. They now represent a viable, affordable, and ethical alternative for fine jewelry, particularly in Western markets.
  4. Self-Purchasing Trends:
    Younger consumers increasingly view diamond purchases as a form of self-reward rather than traditional markers of engagements or anniversaries.

Technological Disruptions: LGDs and Supply Chain Traceability

Lab-Grown Diamonds: A Rising Threat

The affordability, scalability, and ethical appeal of LGDs have positioned them as the most significant disruptor to the natural diamond market. LGD prices, currently at an 80% discount compared to natural diamonds, have accelerated adoption among value-conscious consumers. Technological advancements have enabled the production of larger, high-quality stones, further eroding the exclusivity of natural diamonds.

Supply Chain Innovations

Traceability is becoming a central pillar for diamond producers. Blockchain technologies and other digital tools allow consumers to verify the origin, production methods, and journey of their stones. Beyond compliance, this transparency creates opportunities for storytelling, connecting consumers to the unique narratives behind their diamonds.


Strategic Imperatives for Industry Players

To navigate these challenges, stakeholders across the diamond value chain must adopt proactive strategies:

For Natural Diamond Producers

  1. Invest in ESG Compliance: Ensure ethical mining practices, sustainable water use, and community engagement.
  2. Promote Rarity: Highlight the uniqueness and natural origin of mined diamonds, leveraging these qualities as a counterpoint to LGDs.
  3. Vertical Integration: Streamline operations to enhance efficiency and reduce costs while meeting ESG targets.

For LGD Producers

  1. Focus on Innovation: Continue improving production methods to lower costs and increase scalability.
  2. Address Environmental Concerns: While LGDs are marketed as sustainable, energy-intensive production processes must be optimized.

For Retailers and Midstream Players

  1. Embrace Digital Transformation: Develop e-commerce platforms and invest in digital marketing to engage younger, tech-savvy consumers.
  2. Offer Recycled and Vintage Options: Cater to the growing demand for sustainable and upcycled jewelry.

Looking Ahead: Uncertainties and Opportunities

The future of the diamond industry is far from settled. Several questions remain unanswered:

  • How will LGDs reshape market dynamics?
  • Can natural diamond producers justify their premium pricing amid rising LGD quality?
  • How will geopolitical tensions and regulatory shifts impact supply chains?

Despite these uncertainties, one fact is clear: adaptation is essential. Whether through technological investment, strategic partnerships, or redefining value propositions, diamond industry players must evolve to meet the demands of a changing market.

The industry is at a crossroads. Those willing to innovate, align with consumer values, and embrace technological advancements will not only survive but thrive in this new era.

Legacy, Loyalty & Local Insight: How Karan Kothari Jewellers Is Shaping Vidarbha’s Jewellery Narrative

Published

on

In an exclusive interaction with JewelBuzz, Ushab Kothari, Director – Karan Kothari Jewellers Pvt. Ltd. shares its remarkable journey from a single-store legacy brand to a seven-branch regional powerhouse across Vidarbha. Rooted in trust, transparency, and deep cultural understanding, the brand has built enduring relationships across generations while adapting to changing consumer preferences. From the rise of diamond jewellery and lightweight designs to the growing importance of investment-led purchases and gold saving schemes, the conversation highlights how the brand continues to balance traditional craftsmanship with modern sensibilities. With a strong focus on customer experience, authenticity, and community presence, Karan Kothari Jewellers stands as a benchmark for regional excellence in an increasingly competitive jewellery landscape.

Q1. How has Karan Kothari Jewellers Pvt Ltd evolved over the years, and what defines its identity in the Nagpur jewellery market today?

Karan Kothari Jewellers was established in 1965 with a single vision — to offer the people of Vidarbha jewellery they could trust, at prices that were honest and transparent. Over six decades, we have grown from a single showroom to a seven-branch chain spanning Nagpur, Yavatmal, Amravati, and Chandrapur — covering the breadth of the Vidarbha region. Our most recent branch in Amravati opened in March 2026, which is a milestone we are particularly proud of.

What defines us today is not just our scale, but the depth of the relationships we have built across generations of families. Many of our customers who came to us for their own weddings now bring their children. That continuity is our identity. We are a regional brand — rooted in Vidarbha for over 60 years, deeply familiar with its culture, its occasions, and its buying sensibility — and we believe that local understanding is something no national chain can replicate overnight.

Q2. Nagpur is an emerging jewellery hub — what unique consumer trends and preferences are you observing in this market?

Nagpur is evolving rapidly, and so is its jewellery consumer. A few years ago, purchase decisions were almost entirely gold-centric and occasion-driven. Today, we see a much more confident, informed buyer who researches online, compares designs, and comes into the showroom with a clear point of view.

A few trends stand out: First, diamond jewellery has seen strong and sustained growth across price points — it is no longer just a metro purchase. Second, Kundan and polki have developed a dedicated following among wedding buyers who want something traditional yet distinct. Third, the 18 to 35 age group is increasingly driving purchases, especially for lightweight daily-wear gold and fashion-forward diamond pieces. And finally, investment consciousness is high — our gold saving schemes continue to attract loyal customers who view jewellery as both beauty and financial security.

Q3. How do you balance traditional craftsmanship with modern design sensibilities to appeal to today’s diverse customer base?

This balance is something we think about constantly. Our product range deliberately spans a wide spectrum — from temple-inspired gold sets and intricate Kundan bridal jewellery that honour centuries-old craft traditions, to contemporary solitaire designs, minimalist diamond bands, and lightweight everyday pieces that suit a modern lifestyle.

We work with specialised vendors and artisans for each category, ensuring that craft integrity is never compromised regardless of the design direction. What we have learned over the years is that today’s customer does not want to choose between tradition and modernity — she often wants both, sometimes in the same purchase. A bride may want a classic Kundan set for the main ceremony and a sleek diamond necklace for the reception. We are equipped to serve that entire range.

Q4. What role does retail experience and store design play in influencing customer decisions in your showroom?

Jewellery buying is among the most emotionally significant purchases a family makes, and the environment in which it happens matters enormously. Our showrooms are designed to be welcoming and unhurried — spaces where customers feel comfortable taking their time, asking questions, and trying pieces on without pressure.

We invest in staff training as much as we invest in store design. A knowledgeable, patient sales associate who can explain making charges, hallmarking, and design provenance is as much a part of the retail experience as the lighting or the display case. We also ensure that our showrooms reflect local sensibility — they are not imported formats, but spaces that feel familiar to a Nagpur or Amravati customer.

Q5. With increasing competition from organised and national brands, how do you differentiate your offerings and build long-term customer trust?

Competition from national brands is a reality we welcome — it raises the bar for everyone. But the jewellery business, more than almost any other retail category, is built on trust, and trust is earned locally over time.

Our differentiation rests on three pillars. First, and most importantly, product authenticity. All our jewellery is BIS hallmarked — but we go a step further than most: we are among the very few jewellers in the region who provide the HUID (Hallmark Unique ID) number on both the bill and the product itself. This means every piece leaving our showroom is fully traceable and verifiable, with zero possibility of fake or misrepresented hallmarking. In a market where hallmark fraud remains a genuine consumer concern, this is a commitment we are proud to make and one that customers increasingly ask for by name.

Second, service continuity — when a customer needs an exchange, a repair, or has a question five years after a purchase, they can walk into any of our branches and be assisted. Third, community presence — we have been part of Nagpur’s social fabric for six decades, participating in festivals, occasions, and community events. That presence cannot be manufactured by a new entrant.

We also invest meaningfully in data and customer relationship management, which allows us to engage with customers in a timely, relevant, and personalised way — something we believe distinguishes us even in a competitive landscape.

Q6. How important are festive and wedding seasons, especially occasions like Akshaya Tritiya, in driving your business growth?

Festive and wedding seasons remain the heartbeat of our business. Occasions like Akshaya Tritiya, Diwali, Gudi Padwa, and Navratri are deeply embedded in the buying culture of Vidarbha, and we plan our inventory, staffing, and marketing calendar around them well in advance.

This year, we launched our Maha Labh Utsav campaign from Gudi Padwa through Akshaya Tritiya — a 32-day festive window — with curated offers designed specifically for our regional customer. Akshaya Tritiya, in particular, carries both cultural and investment significance, which makes it uniquely powerful. Customers who may have been considering a purchase for months often use Akshaya Tritiya as the occasion that finalises the decision. We see this season as not just a sales peak but an opportunity to deepen relationships with both new and returning customers.

Q7. Are you seeing a shift in demand towards lightweight, everyday jewellery or investment-led purchases among your customers?

Both trends are simultaneously strong, which is actually a healthy sign for the market. Lightweight, everyday jewellery — particularly in gold and diamond — has seen significant growth among younger working women who want pieces they can wear daily without looking overdressed. This segment has expanded our customer base beyond the traditional occasion-buyer.

At the same time, investment consciousness has never been higher. With gold prices at elevated levels, many customers view gold jewellery as a dual-purpose asset — something beautiful to wear today and a store of value for tomorrow. Our gold saving scheme customers, in particular, tend to be very investment-minded. The two trends are not in conflict; if anything, they reflect a maturing, confident jewellery consumer who expects both aesthetics and value from her purchase.

Q8. What are your future expansion plans, and how do you envision the growth of Karan Kothari Jewellers in the coming years?

We are currently at seven branches across the Vidarbha region, and our immediate focus is on consolidating and deepening our presence in the markets we already serve. Each of our branches has its own local character and customer profile, and there is still significant headroom to grow within our existing footprint.

Beyond physical expansion, we are investing heavily in technology and customer experience — from digital marketing and CRM capabilities to improving how we track and fulfil customer preferences across our branch network. In the medium term, we see opportunities in additional Vidarbha towns where organised jewellery retail is still underpenetrated. Our growth philosophy has always been measured and rooted — we prefer to enter a market where we can serve customers exceptionally well over the long term, rather than chase scale for its own sake.

Q9. What are the consumer trends in gold loans and gold investment schemes?

Gold loan awareness has grown considerably among our customers, particularly in the post-pandemic years where liquidity needs became more pressing. We observe that customers are increasingly comfortable pledging gold as a financial instrument, which reflects a broader sophistication in how people think about their asset portfolio.

Our gold saving schemes, however, are where we have a truly compelling story to tell. This year, our scheme has delivered returns in excess of 100% — and when you benchmark that against popular investment alternatives like the Nifty 50 or other market-linked instruments, we have outperformed them all. Gold has been the standout asset class of the year, and our scheme customers have benefited from that appreciation in full, without the volatility or complexity that equity markets bring.

The scheme serves a dual purpose — it helps customers budget for a significant jewellery purchase in a disciplined manner while simultaneously benefiting from gold’s price movement. The scheme customer is typically a loyal, repeat buyer who feels a deep sense of ownership and commitment to our brand. We have seen steady growth in enrolments year on year, and we continue to structure our schemes to be flexible, transparent, and genuinely rewarding. In a year like this one, the numbers speak for themselves.

Q10. Take us through your product portfolio. What are your premium, top-of-the-line products that are your USP?

Our portfolio spans five core categories: gold jewellery, diamond jewellery, Kundan and polki bridal sets, silver, and jewellery saving schemes.

In gold, our strength lies in a wide range of traditional and contemporary designs — from temple jewellery and antique finish pieces to sleek modern collections — across all purity levels.

In diamonds, we carry a curated range from everyday solitaire and fashion jewellery to high-value bridal suites. This is one of our fastest-growing categories, and we take significant care in sourcing certified diamonds across grading parameters.

Our premium USP is undoubtedly our Kundan and D.Kundan bridal collection. These are handcrafted pieces of exceptional intricacy — necklaces, maangtika, haath phool, and matching sets — that represent the pinnacle of traditional jewellery craft. Brides travelling from across Vidarbha specifically to view this collection is not uncommon.

Together, these offerings allow us to serve a customer at every life stage — from her first gold purchase to her daughter’s wedding trousseau — and that full-lifecycle relationship is perhaps our deepest USP.

As the jewellery market evolves, Karan Kothari Jewellers remains firmly anchored in its core values while embracing innovation and growth. With a measured expansion strategy, continued investment in technology and customer engagement, and a stronghold in bridal, diamond, and traditional jewellery segments, the brand is well-positioned for the future. Its ability to seamlessly blend heritage with modernity, while maintaining unwavering customer trust, ensures that it will continue to be a preferred destination for generations to come across Vidarbha and beyond.
