Hyalite opal is a transparent variety of common opal appreciated for its glass-like appearance and unusual fluorescence. Under normal lighting, it appears nearly colorless, while ultraviolet exposure reveals a distinctive green glow.

This fascinating optical effect is commonly associated with trace amounts of uranium within the mineral structure, making hyalite particularly interesting to mineral enthusiasts and collectors of fluorescent gemstones.

Mexico is a recognized source of natural hyalite opal, producing specimens valued for their transparency and UV-reactive properties.

At 1.80 carats and measuring 11.1 x 7.5 x 4.8 mm, this gemstone features attractive proportions for a custom pendant or collector's display. Its pear shape provides an elegant presentation that highlights its transparency and optical characteristics.

Opal has a Mohs hardness of approximately 5.5 to 6.5, making it more susceptible to scratching and impacts than many traditional jewelry gemstones. Gentle handling and protective settings are recommended.

This individual Mexican hyalite opal combines natural transparency, distinctive green UV fluorescence, and elegant pear-cut styling in a fascinating collectible gemstone.
