How I source

One or two hands
from the ground.

This is how I source the stones of the house. In Sri Lanka, no foreigner is allowed to own a mine. So I do the only honest thing left: I go, I sit at the table, and I choose the stones with my own eyes.

Heat TreatmentHeat treatment is applied to approximately 95% of sapphires. It permanently improves color and clarity. This treatment is widely accepted in the market and must be disclosed. Heated sapphires are worth 30-50% less than untreated ones of equivalent quality.

Untreated (Natural)Untreated blue sapphires represent about 5% of the market and are highly sought after. They command prices 1.5 to 3 times higher than heated stones. A laboratory certificate (GIA, GRS, SSEF, Gübelin) is essential to attest the absence of treatment.

Beryllium DiffusionTreatment that modifies color on the surface or in depth by beryllium diffusion. This treatment significantly affects value (reduction of 80-95%) and must be disclosed. Diffused stones sell at very low prices (3-50 EUR/ct).
