GLC Jewelry Gemstone Identification Report (1 Gem Type)

The Chanthaburi Gemological Laboratory (GLC) issues this report documenting the identification of one gemstone type set within a jewelry piece.

What’s included

• Gem identification one gemstone type set in the jewelry
• Key parameters observable in the mounted piece (such as color and cut)
• Approximate characteristics observable in the mounted piece
• Treatment indications may be stated in the comment field when visible
• Official GLC document issued by Chanthaburi Gemological Laboratory
  
  

Important: When gemstones are mounted in jewelry, certain gemological tests may be limited. Some properties — including weight and measurements — may therefore be estimated or refer to the jewelry piece rather than the individual stone.

Treatment observations may be noted in the comment section when visible, but full treatment analysis is typically performed on loose stones.

Suitable for

• Rings
• Pendants
• Earrings
• Other jewelry pieces containing gemstones
