Trust, Transparency, and Trade: A Retailer’s Guide to Selling Gemstones
By Ramit Kapur: MD, Gemological Science International (GSI) India
A gemstone sale is more than just a transaction; it’s a promise. Customers seek not just beauty but the confidence that what they’re buying holds real value. In an era where gemstones are treated, enhanced, and sometimes even created in laboratories, having the right knowledge isn’t just an advantage; it’s a retailer’s greatest asset.
A well-informed retail team is an empowered one. Understanding gemstone treatments, origins, and certifications isn’t about being burdened with extra responsibility; it’s about enhancing your expertise, making confident sales, and strengthening customer trust. Because at the heart of this business is one simple truth: when retailers lead with knowledge, they lead the industry.
The Truth About Gemstone Treatments
Not all gemstones reach the market in their natural state. Many undergo treatments to improve their color, clarity, or durability, and any treatments and enhancements done, must be disclosed.
Some treatments, like lead-glass filling in rubies, fundamentally alter the gemstone’s structure and require clear disclosure. Others, such as the traditional heat treatment of sapphires, are widely accepted in the industry but still demand transparency. Understanding these nuances enables retailers to sell with confidence, ensuring customers make informed purchases built on trust.
For example, emeralds are naturally filled with inclusions, making fracture-filling with oil or resin a common practice. While this enhances clarity, knowing the type and extent of filling ensures that customers understand how their gemstone will age over time. While an oil-filled emerald may gradually lose its enhancement over time, a resin-filled one may require extra care to avoid exposure to heat or chemicals. Communicating these details not only adds credibility but also ensures customers can enjoy their gemstones for years to come.

Heat treatment in corundum, particularly rubies and sapphires, is a widely accepted enhancement, but its impact varies. A simple heated label doesn’t reveal the full extent of modification. Residues left in healed fractures or surface-reaching cavities can indicate the intensity of treatment, ranging from minor enhancements with little visible impact to significant alterations affecting transparency and overall appearance.
To assess this, the Thermal Enhancement (TE) scale categorizes heat treatment levels, while surface-reaching cavities are further classified based on residue presence, from minimal traces to substantial filling that influences value. Understanding these factors allows retailers to provide clarity and confidence in their sales, ensuring customers appreciate both the beauty and integrity of their gemstones.
This level of classification is not just for high-value stones; modern testing methods now apply to even melee-sized and mounted gemstones. With precise analysis, retailers can confidently present each gemstone’s journey; from its formation to the enhancements it has undergone, ensuring customers feel well-informed and assured in their purchase.
The Power of Origin and Storytelling
Geographic origin is one of the most significant differentiators and selling point when it comes to gemstones.
Sapphires from Kashmir, Myanmar, Sri Lanka, and Madagascar are among the world’s finest, prized for their rich color and saturation. Their rarity, history, and distinct hues shape customer preference. Kashmir sapphires, known for their scarcity, have adorned royal collections, while Sri Lankan sapphires, like the famed Blue Belle of Asia, boast a legacy of luxury. Similarly, Burmese rubies are revered for their deep “pigeon blood” red, and Colombian emeralds for their unmatched green intensity; each origin adding value and prestige.
A gemstone’s origin adds depth, character, and history, making it more than a purchase; it’s a story. Retailers who weave these narratives into their sales approach don’t just sell gemstones; they offer a legacy that resonates with the buyer.
Lab-Grown, Natural, or Imitation? A Retailer’s Advantage
Lab-grown gemstones are often misunderstood, but they are not “fake.” They are created in a controlled environment, and they possess similar physical, chemical and optical properties as their natural counterparts with differences in growth structure. Imitations, however, simply look like real gemstones without possessing their intrinsic properties; like a red glass stone mimicking a ruby.
By understanding these distinctions, retailers can offer customers choices rather than confusion. A customer who seeks affordability and sustainability might be drawn to a lab-grown gemstone, while another looking for rarity will appreciate a natural, untreated gem. Knowledge empowers retailers to guide buyers toward the best fit for their needs, ensuring a sale that feels both personal and professional.
Precision in Terminology: A Game-Changer for Retailers
The way a gemstone is described can shape both perception and value, making precise terminology essential in building credibility and avoiding misunderstandings.
For instance, a natural gemstone forms without human intervention and remains untreated, whereas a genuine gemstone is real but may have undergone enhancements.
Similarly, while heated and treated are often used interchangeably, not all treated gemstones have been heated; some may be clarity-enhanced, fracture-filled, or color-altered through other processes.
Even terms like synthetic and lab-grown need careful distinction, as both refer to man-made stones but carry different consumer perceptions.
A retailer fluent in these nuances isn’t just selling a product; they’re building confidence in their expertise. In an industry where trust drives sales, choosing the right words can be just as impactful as choosing the right gemstones. This expertise not only reassures buyers but also strengthens customer relationships, ensuring repeat business and long-term credibility.

Choosing the Right Certification: One Size Does Not Fit All
Certification is no longer just about verifying authenticity; it’s about making a retailer’s life easier and enhancing the buying experience. Different types of jewelry demand different types of reports, and offering the right format ensures convenience for both retailers and customers.
A comprehensive fusion report is ideal for fusion jewelry, where a single document covering both Polki and gemstones simplifies transactions rather than managing multiple certificates.
For prized gemstones, origin reports add value, helping customers appreciate the significance of a Kashmir sapphire or a Burmese ruby by officially documenting its provenance.
Some buyers prefer pocket-sized reports, offering quick and accessible verification, while others may benefit from digital reports with QR tags, allowing instant access to certification anytime, anywhere; streamlining inventory management and boosting customer confidence.
The key is flexibility; certification should not only authenticate and disclose treatments and enhancements, if any but also support sales, making it easier for retailers to educate, assure, and elevate the overall shopping experience.
In today’s fast-moving gemstone industry, access to information is no longer a challenge, but expertise remains the true differentiator. Treatments will advance. Lab-grown diamonds will become more refined. Consumer expectations will rise. But one thing will remain constant: retailers who embrace knowledge and transparency will always lead. Because at the end of the day, this business isn’t just about gemstones. It’s about trust.

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