Thailand has long been the heart of the colored gemstone and jewelry world — a global hub where crystals are traded, enhanced, cut, and crafted. Around 70–80 percent of the world’s Rubies and Sapphires travel through Thailand on their journey from mine to consumer.
Gems traditionally pass through a seven-tier supply chain on their journey from mine to custodian, increasing in price along the way. Gem Adventurer™ favors mine-to-market relationships that remove as many middlemen as possible, affording genuine chain of custody and mine-level value. This safeguards provenance, allowing us to authenticate gemstone origin and ensure any enhancements are fully disclosed.
Purchasing from trusted industry professionals, all our gemstones are legitimate and guaranteed conflict-free. Gem Adventurer™ prefers long-established contacts, cultivating new sources through extensive international networks in key gem markets and mining centers across Africa, Asia, Europe, and the Americas. Gem Adventurer™ also fully complies with the Kimberley Process, the global system to eradicate conflict diamonds.
As optimal lapidary is critical to gemological beauty, some gemstones are purchased as raw crystals (rough) and expertly cut by our dedicated family cutters in Thailand — formerly the ancient kingdom of Siam, home to some of the world’s finest lapidaries and master cutters.
Deftly cut gems with known provenance are important, but luxury handcrafted jewelry, expertly designed by skilled artisans, is our soul. Gem Adventurer™ jewelry is crafted to precise specifications using authenticated gemstones and precious metals, offering an exceptional range of design and handcrafting capabilities, covering every taste from classic to contemporary.
