The Hunter

Lambert
Vissot

Independent gemmologist. Technical mastery, absolute transparency.

I work from a private office in Bangkok — sourcing, certifying and advising on colored stones of the first rank, for clients whose names never leave the office.

Formation at EIG Monaco

True gemmology is rigorous technical analysis. I trained at EIG Monaco. My approach is strictly analytical — no mysticism. Every stone I evaluate stands or falls on the same tests: crystal quality, precise provenance, optical performance.

I reject the trade’s misleading language — “semi-precious” first among it — so that every stone I present is backed by verifiable fact.

The Five I Hunt

The hunt is narrow on purpose. Five categories; everything else I leave to other dealers:

01

Unheated Burmese Ruby

Natural stones from Mogok, carrying the exact chromium content that true pigeon’s-blood saturation demands.

02

Kashmir & Ceylon Sapphire

Unheated crystal, from the legendary velvety cornflower blue of Kashmir to the brilliance of fine Ceylon material.

03

Colombian Emerald

Selected strictly at insignificant or minor oil — the laboratory grades that guarantee superior underlying clarity and structural integrity.

04

Tanzanian Tsavorite

The finest vivid-green garnets, secured directly at the source in Merelani.

05

Mahenge Spinel

The rarest specimens, hunted for one signature: intense, natural neon fluorescence.

History & Permanence

The stones are older than every border they cross and will outlast whoever owns them. I buy on that timescale — if a stone will not hold its place a generation from now, I pass.
