The workshop features several panel discussions. “Beyond Gems: Next-Generation Applications of OLab-Grown Diamonds” explores LGDs’ potential in various industries beyond jewellery. “Lab-Grown Diamond Growth and Treatment Recipes and Challenges” delves into the intricacies of CVD and HPHT methods. “Diamond Quality Checks and Certification” addresses the crucial need for standardised quality control for gems, jewellery, and seeds. “Lab Grown Diamond Machines and Processing Equipment” will highlight the importance of indigenous equipment manufacturing to bolster India’s self-reliance. The workshop has drawn 150 + participants from the industry.

Key Takeaways

Diamond Quality Checks & Certification:

  • Advanced treatments challenge LGD grading and certification accuracy.
  • Key challenges: ensuring grading accuracy, standardization, and detecting undisclosed synthetics.
  • Emphasis on advanced testing methods, tech-driven grading, and industry consistency.
  • Traceability of tested items is a major issue.
  • LGDs are both supplementary and complementary to the diamond industry.
  • Mimicking natural diamond growth patterns in LGDs remains a challenge.

LGD Growth & Treatment Recipes: Key Takeaways

  • Increasing nitrogen in HPHT accelerates growth, benefiting gem-quality diamonds but not other industrial uses.
  • Focus on optimizing growth parameters, impurity control, and enhancement for superior diamonds.
  • Challenges include consistency, reducing defects, scalability, and reliance on high-purity raw materials.
  • Future focus on refining processes, improving sustainability, and enhancing research-industry collaboration.

Diamond Quality Checks & Certification (Continued): Key Takeaways

Strengthening quality assurance frameworks is essential to ensure consumer trust globally.

Grading LGDs differs from natural diamonds, especially in color; secondary reference masters needed.

Labs must assess hue saturation and intensity, not just color for LGDs.

Clarity characteristics differ due to metallic inclusions in LGDs.

Color grading challenges arise in borderline clusters where AI struggles.

LGDs are cut for perfection, unlike natural diamonds, which are cut for weight retention.

Chandukaka Saraf: 200 Years Of Legacy, Trust and The Evolution Of Jewellery

Published

on

Few businesses have the privilege of celebrating a journey spanning two centuries. For Chandukaka Saraf, this milestone is not a celebration of longevity; it is a celebration of the generations of customers, employees, artisans, partners and communities who shaped the journey.

Established in 1827 in Baramati, Chandukaka Saraf began as a family enterprise and has grown into a jewellery brand with 19 stores across Maharashtra and Karnataka. The brand is looking to add another five to seven stores in the current calendar year. More than 1,000 employees contribute to the organisation’s journey.

Legacy Built Across Generations

From Late Shri Bhaichandji Shah, whose commitment to purity and excellence laid the foundation, to Late Shri Jyotichandji Shah and Late Shri Chandulalji Shah, who strengthened customer relationships and expanded the business, and Late Shri Jindattaji Chandulal Shah, who played a pivotal role in business growth, employee welfare and ethical practices—the family journey has been one of continuity and evolution. Today, Chairman Shri Kishorkumar Jindatta Shah and Managing Director Mr. Samyak Kishorkumar Shah are leading the next phase.

For Chairman Shri Kishorkumar Shah, the 200-year milestone is deeply personal. It represents generations of trust and responsibility.

When Customers Changed, Jewellery Changed Too

Over two centuries, India has undergone significant social and economic transformation, and jewellery has evolved alongside it. Traditionally associated with weddings, festivals and major family occasions, jewellery today has become increasingly connected to personal expression.

Customers are choosing jewellery to celebrate first salaries, professional milestones, birthdays, anniversaries and personal achievements. Traditional gold continues to hold emotional significance, while diamonds, gemstones, silver and lightweight designs have become part of modern wardrobes.

This evolution can be seen in heritage jewellery, where traditional craftsmanship and motifs are being interpreted through contemporary designs. Today’s customer wants the reassurance of heritage while also seeking individuality, versatility and convenience.

For Chandukaka Saraf, understanding this shift means serving both customers who value tradition and younger consumers with new expectations.

Samyak Shah, Managing Director, Chandukaka Saraf.

“Our responsibility is to nurture and cherish both tradition and modernity.”

“Our role is to understand and serve both, while continuously evolving without compromising the trust that defines Chandukaka Saraf.”

When Technology Became Part of Trust

While designs have changed, some things have remained constant: purity, craftsmanship, transparency and trust.

Chandukaka Saraf has adopted technology and new practices to strengthen customer confidence. Long before hallmarking became a formal industry standard, the brand introduced its own hallmark as a representation of its commitment to purity and authenticity. It was also among the early pioneers in introducing Karatmeters at its stores, enabling customers to check gold purity through technology.

From Baramati to the Future

From Baramati to 19 stores across Maharashtra and Karnataka, the brand has expanded while retaining its connection with its roots. With five to seven new stores planned in the year, the brand is preparing to take its legacy into newer markets.

In the evolving jewellery in Maharashtra landscape, the opportunity lies in combining the reassurance of heritage with the expectations of a new generation.

What Changes, and What Remains

A 200-year legacy is a story of evolution—adapting to changing times while preserving the values that endure. It is about understanding what needs to evolve while protecting what should remain constant.

Designs, technology and consumer aspirations will continue to evolve, but the desire to celebrate meaningful moments, give something lasting and create memories will remain.

From Baramati in 1827 to its growing presence today, Chandukaka Saraf continues a story built across generations—where heritage jewellery meets modern aspirations, and changing times are met with an enduring commitment to purity, transparency and trust.
