⭐ Why UV Flashlights Are Important for Gem & Mineral Identification

Different gemstones and minerals react uniquely under ultraviolet light. A high-quality UV flashlight helps identify:

1. Fluorescence Patterns

Some gemstones fluoresce brightly under UV:

• Ruby

• Sapphire

• Diamond

• Amber

• Opal

• Fluorite

2. Treatment Detection

UV can reveal:

• Resin-filled jade

• Glass-filled ruby

• Polymer-treated turquoise

• Fake jadeite vs. genuine Type A jade

3. Authenticity Verification

True 365nm UV helps reveal:

• Dyed stones

• Coatings

• Synthetic materials

4. Mineral Identification

UV light is used to identify minerals such as:

• Calcite

• Aragonite

• Scheelite

• Willemite

• Sodalite

For accuracy, true 365nm UV-A is the professional standard, because it minimizes visible purple light and reveals fluorescence more clearly.
