The Story

HOW & WHERE IT ALL BEGAN

It all started in 1996, when Alexander Leuenberger moved to Madagascar to start a new venture that changed his life.

During the 5 years living in this beautiful country, he learned to purchase rough and cut gemstones, set up a cutting factory and different mining operations, which lead to an ownership of the most productive mechanized sapphire mine of Madagascar.

The art is in the cut

The true value of a gemstone is not only in its form –

but the trained eyes, hands, and heart transforming the stone into a treasure.

A masterful cut of a rough stone reveals its brilliancy, color and character.

It calls for multidimensional imagination and an innate instinct.
