Rough materials
created by Dalloz

A pure source material

Owing to their skills, ingenuity and environmental concerns, teams in our French factory produce a very pure alum powder, without any discharge into nature.

We recently achieved, thanks to massive investments in R&D, the feat of removing Chromium 6 (a highly carcinogenic product) from whole of our ruby lines, which is in perfect compliance with REACH norm.

An ecological process

The process of recreating a rough material identical to what takes centuries to develop naturally, requires a tremendous amount of energy. Concerned with our environmental footprint, we utilize hydropower and recycling of discharges from surrounding factories to produce rough material that has very limited carbon impact.
