Gems That Fluoresce: A Luminous Exploration of Nature's Hidden Brilliance

Introduction

The world of gemstones is filled with a myriad of wonders, including a remarkable subset that fluoresces - emitting a radiant glow when exposed to certain wavelengths of light. These luminescent gems captivate the imagination with their ethereal beauty and possess extraordinary scientific properties that make them highly valuable in various fields.

Fluorescence: Unveiling the Hidden Glow

Fluorescence is a phenomenon in which a substance absorbs light of a specific wavelength and re-emits it at a longer wavelength, giving off a visible glow. In the case of fluorescent gems, the absorbed light originates from sources such as ultraviolet (UV) radiation or X-rays. This process occurs due to the presence of specific elements or impurities within the gem's crystal structure that act as "activators."

Types of Fluorescent Gems

A wide range of gemstones exhibit fluorescence, including:

• Diamond: Blue, green, yellow, orange, red
• Ruby: Red, orange, yellow
• Sapphire: Blue, green, yellow, pink
• Emerald: Green, red
• Alexandrite: Green, red, orange
• Topaz: Blue, yellow, brown
• Opal: Green, blue, red

The intensity and color of fluorescence vary greatly depending on the gem's composition, impurities, and treatment history.
