LAB [HTHP Cultured] Gem Diamond

By special request, we have become a “supply broker” to a few companies, that need the extra confidence & flexibility of carats in different sizes and grades of “rough cast”; not polished.

This business has evolved and grown out of the synthetic industrial diamond business of China, which Anglo Sterling LTD has played an important part of, for more than 35 years.

We focus on top Grades A and A+ in sizes 1.5 to 2, 2 to 3, 3 to 4, 4 to 5, 5 to 6, 6 to 7 and 7 to 8 carats. Can we help you?
