Why Certification Matters

When you invest in a gemstone—especially high-value gems like Ceylon sapphires, rubies, or spinels—you want assurance of its authenticity, quality, and value. A gemstone certification, issued by a reputable gemological laboratory, gives you exactly that.

Without proper certification, it’s easy to overpay for a stone, buy a treated gem without knowing, or end up with a synthetic instead of a natural gem.

 

What is a Gemstone Certificate?

A gemstone certificate (also called a gem report) is an independent, professional evaluation of your stone’s characteristics. It details important factors such as:

• Type of gemstone (e.g., natural sapphire, ruby, spinel)
• Origin (where the gem was mined)
• Color and clarity grades
• Carat weight
• Cut and shape
• Any treatments (e.g., heat enhancement)

 

Trusted Certification Bodies

Not all certificates are equal. Leading international labs include:

• GIA – Gemological Institute of America
• IGI – International Gemological Institute
• GRS – GemResearch Swisslab
• NGTC – National Gemstone Testing Center

For Sri Lankan gems, local labs like the NGJA (National Gem and Jewellery Authority) are also trusted.

 

How Certification Protects You

Certification ensures you’re buying exactly what’s advertised. It can also make your gemstone easier to resell or insure. For collectors, certificates add credibility and value to your investment.
