Own treasure.Build something lasting.

GemBank is where a collection becomes a legacy — a vaulted record of every stone, every certificate, every chapter of the hunt. This is what you're really building.

  • A vault you own

    Every stone you win or buy is held with its certificate and full provenance — yours to keep, trade, or set.

  • A collection with history

    Track origin, treatment, and carat across your hoard. Watch it grow, raid after raid.

  • A path to legend

    Rise from Raider to Kraken as your collection deepens. Status you earn, not buy.

The GemRaider Charter

Gemstones should be transparent, collectible, and worth keeping.

We are privateers with papers — licensed, documented, legitimate. We source natural, earth-mined sapphires and rubies in Bangkok and bring them to you with their full provenance intact, so collecting feels like an adventure you can trust.

No lab-grown stonesNo mystery boxesOnly real treasure
Provenance · Why GemRaider

Heritage gemstones, brought into the light.

The gem trade has hidden its workings for too long. GemRaider pairs the romance of discovery with the rigor of fine-jewelry provenance — real stones, real origins, real adventure, nothing obscured.

  • Sourced in Bangkok

    We buy natural, earth-mined sapphires and rubies at the world's gem-trading heart.

  • Fully disclosed

    Every treatment, origin, and certificate is stated plainly — no exceptions.

  • Real treasure only

    No lab-grown stones. No mystery boxes. Only genuine gemstones worth collecting.

The Atelier · Jewelry

Set a stone you found into something to keep.

Take any stone from your GemBank and commission an heirloom piece — designed with you, set by hand, and finished in aged brass and fine metals. Every commission keeps its certificate and story.

  • Bespoke settings around your own stones
  • Hand-finished by the GemRaider atelier
  • Provenance travels with the piece
