Hyalite Opal (Glass Opal) 1.32 CT

RECOMMEND POINT
This is a rare stone of over 1 carat for hyalite.

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

This is one of the rarest types of opal.

Its characteristics are a glassy luster and a fluorescence not present in other opals.
What is very mysterious is that it emits a neon green color when exposed to ultraviolet light (black light).

An even more important feature is the size.

Hyalite opal rough stones have the appearance of a collection of small, transparent lumps that resemble glass particles, and look like drops of water that have fallen one by one and solidified.

0.3 carats is a sufficient size, so 1 carat is quite large.

Hyalite is also closer to nature.
It is normal for gemstones to contain inclusions and chips, but for this size and clarity we can highly recommend it.

Please enjoy this rare, large hyalite opal.
