RARITY OF FLUORESCENT DIAMONDS

RARITY OF FLUORESCENT DIAMONDS

Less than 6% of the diamonds submitted to AGS Laboratories reach our color and intensity requirements.

Fluorescent diamonds shine brighter than the rest in direct sunlight. It comes from the presence of trace elements naturally contained within a diamond during the carbon crystallization process. These trace elements make each fluorescent diamond truly one of a kind. Because fluorescence only occurs in natural diamonds, it’s also a reliable indicator of a gem’s authenticity. The 4Cs (Color, Clarity, Cut and Carat Weight) are the grading factors utilized by gemological laboratories to assess the value of every stone.

Fluorescence however, has its own category: intensity. The higher the intensity, the stronger the diamond’s natural glow.

Rarity of Fluorescent Diamonds submitted to AGS Laboratories:

● 94.5% have “Negligible” fluorescence
● 3.6% have “Medium” fluorescence
● 1.5% have “Strong” fluorescence
● 0.34% have “Very Strong” fluorescence
