一、无荧光（None or None/Weak）

When diamonds exhibit no visible fluorescence or only very faint fluorescence under ultraviolet light, they are classified as "None" or "Weak". This is denoted as "IF" (Internal Flawlessness) in the GIA grading system.

二、弱荧光（Faint）

Faint fluorescence is characterized by a subtle glow when exposed to UV light, often described as a pale blue or green hue. In the GIA scale, this is labeled as "F" (Faint) or "FF" (Faint Blue).

三、中等荧光（Medium）

Moderate fluorescence produces a noticeable glow, typically appearing as a medium blue or sometimes yellow-green color. The GIA grades this as "M" (Medium) or "FM" (Medium Blue).

四、强荧光（Strong）

Strong fluorescence displays a vivid and intense glow, often described as a bright blue or even white. This category is designated as "S" (Strong) or "VS" (Very Strong) in the GIA system.

五、极强荧光（Very Strong）

Very strong fluorescence, also known as "VVS" (Very Very Strong) in GIA grading, indicates a highly intense glow, sometimes resembling daylight or neon blue.

六、超强荧光（Ultra Strong）

This is a rare classification, denoted as "U" (Ultra Strong) or "UI" (Ultra Intense), where the diamond exhibits an extremely bright and overpowering glow.
