Fascinating fluorescent rare stone!
Hyalite Opal (Glass Opal) 0.90 CT

RECOMMEND POINT
An exceptionally rare fluorescent opal!
This is a highly recommended stone for your collection.

Unlike precious opals, which have play of color like black opals and Mexican opals, common opals do not have play of color.

Instead, this gem has an enchanting special effect.

Hyalite opal comes from the Greek word hualos, which means glass.

Because of its glass-like appearance, it is commonly known as glass opal and is extremely difficult to produce among opal species.

Because it is the rarest, it is also called the mysterious stone.

As it is called glass opal, it is characterized by unique bubble-like and rhytidian-like inclusions.
It gives the impression of being similar to moldavite, a famous natural glass.

Rough hyalite opal has the appearance of a collection of small, transparent lumps like glass particles, and resembles drops of water that have fallen one by one and solidified.
For this reason, large sizes are not available and 0.3 CT is sufficient, so 0.9 CT can be said to be very large.

What is particularly mysterious is that it emits a neon green color when exposed to ultraviolet light (black light).

It contains trace amounts of uranium, which causes it to fluoresce in ultraviolet light.

By the way, you may be hesitant to hear the word uranium, but it is an extremely small amount and has no effect on the human body, so please rest assured.

Of course, not all hyalite contains uranium; it is a natural product that happens to contain it by chance.

Please enjoy the rare hyalite opal.
