GCAL by Sarine is pleased to support the launch of a new range of laboratory-grown diamond jewelry by Nima Jewellers, created specifically for retailers in the United Kingdom. The collection showcases GCAL by Sarine 8X precision-cut diamonds, representing the highest standard of documented cut performance and craftsmanship.

Distributed by Nima Jewellers in the UK, the collection includes rings set in 18-carat yellow gold or platinum, featuring laboratory-grown diamonds in 1, 1.5, and 2 carat sizes. In addition to finished jewelry, Nima Jewellers also offers loose GCAL 8X diamonds starting at 1 carat, along with bespoke manufacturing services for retailers seeking custom designs such as earrings, pendants, and necklaces.

“The GCAL 8X range is exceptional because it incorporates the latest engineering technologies for precision cuts,” said Anand Parekh, Director of Business Development at Nima Jewellers.

The GCAL 8X Ultimate Cut Grade was developed to identify truly exceptional diamonds. While more than half of all round brilliant cut diamonds receive traditional “Excellent” cut grades, fewer than 1% meet the rigorous criteria required to achieve 8X certification. This distinction reflects the highest levels of optical symmetry, light performance, craftsmanship, and overall beauty.

The GCAL 8X Ultimate Cut Grade gives buyers a way to confidently select the most brilliant and beautiful diamonds, even when purchasing online.

“GCAL 8X is designed to bring measurable precision and transparency to the top end of the cut spectrum,” said Angelo Palmieri, President of GCAL by Sarine. “In a marketplace where many diamonds share the same traditional ‘Excellent’ designation, 8X identifies the rare stones that meet the highest thresholds for optical symmetry, light performance, craftsmanship, and beauty. We are pleased to support Nima Jewellers in bringing this level of documented precision and differentiation to UK retailers.”

The GCAL by Sarine 8X jewelery range will be presented by Nima Jewellers at major UK trade events, including the Retail Jeweller Festival in London (March 16–17) and The Jewellery Show at Olympia London (September 2–3).

GCAL by Sarine is proud to collaborate with partners worldwide who share our commitment to transparency, precision, and innovation in diamond grading.
