The Dual Evaluation Process

Color saturation, clarity, structural integrity — the rigorous tests every stone must pass before it is cataloged.

Every stone that enters the Elysion atelier passes through two gates. One is measured by instruments; the other by a lifetime of intuition. Only a stone that clears both earns its place in the catalogue.

The Scientific Eye

Colour saturation is measured under controlled light. Clarity is examined beneath magnification. Structural integrity is tested against the quiet violence of time — the fractures, the inclusions, the honesty of the matrix.

These numbers are not decoration. They are the stone’s passport, recorded with the precision of a museum and archived for every specimen we have ever catalogued.

The Artistic Eye

But numbers alone cannot choose a stone. The master evaluator turns it slowly in the hand, watching how light enters and how it leaves. Some stones are technically perfect yet remain silent. Others carry a presence no instrument can name.

“We measure what can be measured. Then we listen for what cannot.”
— The Master Evaluator, Tehran Atelier

Two Gates, One Promise

A stone that passes both evaluations is not merely sold; it is entrusted. It carries its certificate like a passport, and its story like an inheritance.

This is the dual evaluation. This is the Elysion promise.
