Private Gem Office · Bangkok
The Pinnacle of Colored Gemstones
Independent Sourcing · Absolute Discretion
ScrollWelcome to the private office of Lambert Vissot.
I operate alone from Bangkok, buying unheated rubies, sapphires and rare spinels for private collectors and jewelry houses worldwide — at origin, in person, before the stones ever reach the public market.
With Whom You Work
One hunter.
No middlemen.
Lambert Vissot, gemmologist — trained at EIG Monaco, formed in the Bangkok trade. Every stone is bought at origin, in person, and offered with its flaws in writing. By the time a stone reaches a boutique window, four margins stand between you and the ground. Here there are none.
Meet the Hunter →What You Obtain
The stone, the cut,
the piece, the proof
The Stone
The rarest fraction of what the ground produces — investment grade, bought at origin against your mandate, certified by Gübelin, SSEF, AGL or GIA. Unheated only, no exceptions — emeralds solely at insignificant or minor oil.
The Cut
Precision cutting under my own hands — advanced geometry, executed to tolerances few workshops attempt, so the stone returns every point of light it owns.
The Piece
High jewelry, one of one — designed strictly around the stone and finished to the standard of the great houses, directed from Bangkok.
The Proof
Certificates, provenance, photographs, the hunter’s written assessment — the file your insurer and your heirs will want.
The Vault
Not everyone
receives a key
Behind the key: the active portfolio, the bespoke atelier, a direct line to the hunter. Keys are never sold and cannot be requested outright — they are earned with a first acquisition.
