The Trinity of Precision and Rarity
Premier Gems Trading, established in 1982, anchors the group’s reputation as a leader in sourcing and trading the world’s rarest rubies, sapphires, and diamonds. Based in Bangkok—the global hub for gemstone trade—this division holds one of the largest gemstone inventories including rough and polished diamonds and maintains rigorous standards to ensure unmatched quality and repeat-order consistency.
Premier Diamond Cutting, founded in 1979 and formally launched in 1983, became the manufacturer and wholesaler of impeccably proportioned, uniform polished diamonds known as the “Premier Cut.” With master gem cutters and assorters focusing on symmetry and light performance, every stone—from 0.01 ct melee to fancy shapes over 0.30 ct—shows brilliance at its peak.
This Bangkok Diamonds news report highlights their innovations, such as the “Hearts & Arrows” and “Double Star” cuts, which combine technical perfection with visual beauty. They have also introduced patented designs like the “Sunflower Cut” and “Premier 65,” crafted to maximize fire, scintillation, and brilliance.
