Tanzanite is unearthed in a single place: the Merelani hills at the foot of Kilimanjaro. Everything the Maison makes begins there — with rough crystal sorted by hand before it ever reaches the cutting room.
Commercial tanzanite is found only in the Merelani hills of northern Tanzania, near the foot of Kilimanjaro — a deposit a few kilometres long.
The crystal shows different colours along its three axes — blue, violet and burgundy — which is why the cutter’s first decision matters most.
A single known source and a finite deposit: estimates give the mines decades, not centuries, of remaining production.
Identified in 1967, tanzanite is one of the youngest gemstones in fine jewellery — with no antique supply to draw on.
Every stone is bought rough, directly from certified small-scale mines, and travels with its documentation from the sorting table to the cutting wheel to the setter’s bench. When a client asks where their stone comes from, the atelier can answer with a place, a date and a parcel number.
THE MAISONTanzanite asks for gentler habits than diamond: no ultrasonic cleaners, no sudden heat, a soft cloth after wearing. Every Maison Tanzanite creation may return to the atelier for cleaning and service, for life.
