The key role of a gemologist expert in Paris

Gemology is a scientific and market discipline:

  • Identification: natural, treated (heated, filled), or synthetic stone.
  • Quality assessment:
    • Diamond: the 4 Cs (Carat, Color, Clarity, Cut).
    • Colored stones (ruby, sapphire, emerald): intensity, saturation, origin (a determining price factor).
  • Valuation: assessment based on condition, fashion, rarity, and current market.

Precious stone appraisal services

  • Oral appraisal: a quick initial opinion to determine if further analysis is worthwhile.
  • Written report (for inheritance, division of assets, insurance, sale):
    • Comprehensive technical description
    • Market value or replacement value
    • Legally binding and archivable document to protect your assets

How is a precious stone estimated?

A rigorous protocol ensures reliable conclusions:

  1. Initial observation: 10x loupe, checking inclusions and cut.
  2. Weighing: carat balance (estimation if stone is mounted).
  3. Instrumental analysis: binocular microscope, refractometer, spectroscope, filters, UV…
  4. Synthesis & report: a true identity card for the gem with photos and measurements.

Preparing for your jewelry & stone appraisal

Authenticity: a major challenge for antique jewelry

The market includes imitations and synthetic materials (e.g., moissanite for diamond, composite ruby).

Only a certified gemologist can reliably distinguish a heated ruby from a composite, or a natural diamond from another material. A prior appraisal ensures the sale and purchase of jewelry at a fair price.
