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.

Jewelbox Expects Festive Momentum as Consumers Embrace Versatile Lab-Grown Diamond Jewellery
In an exclusive JewelBuzz interview, Vidita Kochar Jain, Co-founder, Jewelbox, shares insights on festive jewellery demand, evolving consumer preferences, the growing acceptance of lab-grown diamonds and the brand’s latest personalised diamond offering, Signed Diamonds
Jewelbox, a contemporary lab-grown diamond jewellery brand, is witnessing an evolving jewellery consumption landscape, with consumers increasingly prioritising versatile designs, personal expression and value. As festive and wedding purchases gain momentum, the brand sees growing opportunities in everyday fine jewellery, gifting and personalised diamond offerings.

In an exclusive interview with JewelBuzz, Vidita Kochar Jain, Co-Founder, Jewelbox, discusses expectations for the current festive season, changing consumer sentiment, the growing appeal of lab-grown diamonds and the brand’s latest festive offering, Signed Diamonds, which brings a personal touch to diamond jewellery.
Jb: What are your expectations with regard to jewellery sales during the current festive season?
Vidita Kochar : Every year, the festive season is a strong period for jewellery consumption, with both gifting and self-purchases contributing to demand. Jewellery continues to hold a unique position in Indian celebrations, but the nature of consumption is evolving. Customers are increasingly looking beyond traditional occasion-led purchases towards versatile pieces that can be worn regularly. At Jewelbox, we expect lab-grown diamond jewellery to benefit from this shift, particularly in categories such as everyday fine jewellery, statement pieces and gifting. We remain optimistic about festive demand and expect to see sustained momentum across our retail and digital channels.


Jb: What is the current consumer sentiment regarding jewellery purchases?
Vidita Kochar: Consumer sentiment towards jewellery remains encouraging, although purchasing behaviour is becoming increasingly discerning. Customers are placing greater emphasis on design differentiation, product quality, versatility and the overall value proposition. There is also a discernible shift towards self-purchasing, with consumers increasingly viewing jewellery as a personal expression rather than an occasion-led purchase. Within this evolving landscape, lab-grown diamonds are finding greater acceptance, particularly among younger consumers who appreciate the ability to access fine jewellery across a wider range of designs and price points.
Jb: Are you launching any festive or wedding collections this season? If yes, please share the details?
Vidita Kochar: At Jewelbox, our focus this season is on offering jewellery that brings together contemporary design, versatility and craftsmanship. Our collections cater to festive celebrations as well as weddings, with designs that transition effortlessly from special occasions to everyday wear.
With changing consumer preferences reshaping the jewellery landscape, versatility, personalisation and design-led offerings are emerging as important purchase drivers.


Jewelbox’s focus on contemporary lab-grown diamond jewellery and innovative concepts such as Signed Diamonds reflects its approach to connecting with the evolving expectations of modern consumers. As the festive and wedding seasons bring renewed opportunities for the industry, the brand remains focused on making diamond jewellery more accessible, expressive and meaningful.
