Natural gemstones are formed in the earth over millions of years through geological processes, while synthetic gemstones are created in laboratories using advanced technology. Both can have similar physical and optical properties, but natural gemstones are generally more valuable. AIG's comprehensive reports clearly identify whether a gemstone is natural or synthetic, providing transparency for buyers and sellers.
Synthetic gems are crystalline materials with the same chemical composition as their natural counterparts, while glass is an amorphous material. Professional gemological testing using specialized equipment can identify these differences. AIG uses advanced laboratory instruments to accurately distinguish between synthetic gemstones and glass imitations, ensuring you receive accurate identification in your report.
The beauty of a gemstone is evaluated based on the "Four Cs" for diamonds (Cut, Color, Clarity, and Carat weight) and similar criteria for colored gemstones including color intensity, clarity, cut quality, and carat weight. AIG's expert gemologists use internationally recognized grading standards to assess these characteristics, providing detailed analysis in our comprehensive reports.
For diamonds, clarity grades range from Flawless (FL) to Included (I). The best clarity grades are Flawless (FL), Internally Flawless (IF), and Very Very Slightly Included (VVS1, VVS2). For colored gemstones, clarity standards vary by type, with eye-clean stones generally being most desirable. AIG follows the widely accepted GIA diamond grading system and provides detailed clarity assessments in all our reports.
