Gemstones from Our 2026 Thailand Buying Trip

Fresh from Bangkok! This collection features gemstones hand-selected by the Moriarty family during our 2026 Thailand buying trip.

Bangkok is one of the world’s great centers for colored gemstones, giving us the opportunity to examine stones in person and select the ones that stand out for their color, rarity, cutting, and overall beauty.

Many of these gems are one of a kind. Once they're gone, we may not be able to find another quite like them.

Explore our newest Bangkok finds below, or let us help turn your favorite into a one-of-a-kind custom piece of jewelry.
