UV fluorescent rare stone!
Hyalite Opal (Glass Opal) 0.87CT

RECOMMENDED POINTS
Opal that fluoresces under ultraviolet light!
Enjoy the fascinating colors.

Hyalite opal has the characteristic of glowing when exposed to ultraviolet light.

Because it looks like glass
It has nicknames such as glass opal.
It is one of the most difficult opal species to produce.

The characteristic is that it is called glass opal
Unique bubble-like and rhytidian-like inclusions can be seen.
It gives the impression of being similar to moldavite, a famous natural glass.

Hyalite opal rough
The appearance is a collection of small, transparent chunks like glass beads.

It becomes like the water droplets that have fallen drop by drop have solidified.

Therefore, 0.3CT is a sufficient size.
When it comes to 0.8CT and 0.9CT
I'd say it's very big.

And the most distinctive feature is its ultraviolet fluorescent color.
This is due to the presence of trace amounts of uranium.
It reacts to ultraviolet light with fluorescence.

It inevitably contains tiny inclusions.
This may seem like a minor point compared to this major feature.

Rare hyalite opal
Please enjoy.

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.
