For precious stones with a personal touch, look to O Thongthai. The brainchild of Central Saint Martins alumnus Chanyaporn Thongthai, the eponymous label was born in 2014 out of the founder’s personal dissatisfaction with jewellery. Taking care to ‘create something meaningful for the owner,’ O Thongthai’s tailored approach to ‘small, precious, shiny and sentimental’ gems has already secured an impressive list of collaborations. Expect signet rings that wouldn’t look out of place on the red carpet, 14K gold bracelets nostalgic for the bustling streets of Bangkok, and necklaces dripping with diamonds, sapphires and rubies (usually found around the necks of the likes of A$AP Rocky).
