Where can you get your diamond appraised in Nice? Jewelry expertise since 1961

Having a diamond appraised involves more than simply assigning it a monetary value. A professional assessment makes it possible to precisely identify the stone's nature, evaluate its quality, and determine its value based on internationally recognized gemological criteria.

At Bijouterie Artero Stéphane—a jeweler in Nice since 1961—we have been appraising diamonds, antique and contemporary jewelry, and gemstones for many years. Our experience, combined with state-of-the-art equipment in our workshop at 22 Bis Boulevard Dubouchage, enables us to conduct reliable, rigorous analyses—whether for asset valuation, insurance purposes, estate settlements, division of assets, or a planned sale.

Natural Diamond and Laboratory-Grown Diamond Expertise – Artero Jewelry, Nice

Where can you get your diamond appraised in Nice?

Expertise based on modern analyses

The diamond market has undergone significant changes with the advent of lab-grown diamonds. Today, professional assessment must be able to definitively identify a natural diamond and distinguish it from a lab-grown one, whether produced via the HPHT or CVD process. To understand the implications of this distinction, our guide details the differences between natural and lab-grown diamonds.

That is why our workshop is equipped with specialized instruments to perform these checks using methods currently recognized in gemology. We utilize, among other tools, a spectrometer designed for diamond analysis, as well as fluorescence and phosphorescence observation techniques under ultraviolet light—methods essential for detecting various characteristics specific to lab-grown diamonds.

These advanced examinations complement standard analyses based on the famous "4Cs"—Carat, Color, Clarity, and Cut—alongside an assessment of the stone's fluorescence, inclusions, and growth characteristics. To learn more, discover how diamond quality is evaluated in the jewelry industry.

Why have a diamond appraised?

A professional appraisal may be required in many situations:

plans to buy or sell a diamond;
assessment of an antique diamond or family heirloom;
verification of a stone's exact nature;
confirmation of whether a diamond is natural or lab-grown;

Every appraisal is conducted with complete confidentiality and is based on an in-depth analysis of the stone.

"Valuing a diamond is not merely a matter of weighing and pricing. It is about tracing its history and understanding its inclusions and its journey. Every stone brought to the studio carries a family story; I treat it with the same respect I accord a bespoke creation." — Stéphane Artero, jewelry designer in Nice
