Gems and Precious Stones

Topaz fluorescence refers to the phenomenon where topaz gemstones emit visible light when exposed to ultraviolet (UV) light. This fluorescence can vary in intensity and color depending on the presence of trace elements within the crystal structure, with some topaz displaying bright blue or yellow hues under UV light. It's a sought-after characteristic in gemology, as it can enhance a stone's appeal and indicate its quality. However, not all topaz exhibits fluorescence, making it a unique feature for certain specimens.

Blue topaz is considered a semi-precious stone rather than a precious stone. While it is valued for its beautiful blue color and clarity, it does not hold the same status as precious stones like diamonds, rubies, sapphires, and emeralds. Blue topaz is widely available and often treated to enhance its color, contributing to its lower rarity and price compared to precious gemstones.

Opals are a type of mineral composed of silica and water, so they do not have a distinct smell.
