The International Institute of Diamond Grading & Research (IIDGR), part of De Beers Group, said that it has established four new diamond grading partnerships with leading diamond jewellery retailers in Thailand, Vietnam and China.

The new partners are Aurora Diamond in Thailand, DOJI Group in Vietnam and Chow Tai Seng and CHJ in China. While the former two represent IIDGR’s first grading partnerships in Thailand and Vietnam respectively, the tie-ups in mainland China are a further extension of the lab’s presence in the country.

This year, IIDGR has already announced a number of partnerships with retailers in Asia, which include Soo Kee Group in Singapore and China, Lukfook Jewellery in Hong Kong and Macau, and I-PRIMO in Japan.

The new partnerships will see IIDGR diamond grading reports provided for the following diamond jewellery collections for each retailer:

• Aurora Diamond, Thailand – the Ultimate Love Collection. Each grading report will have a tailored Aurora-branded cover.
• DOJI Group, Vietnam – the Wedding Land brand, proprietary Infinity Love line of diamonds carrying 99 facets, and the 10 Hearts & Arrows diamonds in its Diamond House brand.
• Chow Tai Seng, China – the proprietary Love 100 brand. Each Love 100 diamond will be inscribed with both the Chow Tai Seng logo and a unique identification number from IIDGR.
• CHJ, China – the Cupid Solitaire brand of diamonds with eight Hearts & Arrows will have co-branded diamond grading reports. Each diamond will bear the inscription of both the CHJ Cupid Solitaire logo and a unique IIDGR identification number.

Jonathan Kendall, President, IIDGR, said: “We are experiencing rapid growth in demand for IIDGR’s diamond grading reports from retailers in Asia. Our ability to offer tailored grading reports to our partners, whether that be through co-branding or bespoke designs, combined with our highly precise grading services and more than 120 years of De Beers Group’s diamond expertise, has been extremely well-received by both retailers and consumers alike.”
