Large rare stone crystal!
Oligoclase 7.03CT

RECOMMEND POINT
This large oligoclase is highly recommended for your collection.

Oligocrase boasts high transparency

Oligoclase belongs to the mineral group called feldspar and is a gemstone located between andesine and albite.
It is also a sister stone to labradorite and moonstone.

Oligoclase comes from the Greek words "oligo" and "klassos crack", meaning that it is more difficult to break than other gemstones.
(Actually, since it is a natural stone, it cannot be compared.)

By the way, as a side note, crystals that have special optical effects (lame-like light phenomena) such as oligoclase, andesine, and labradorite are called sunstone.

As you can see from the complex compositional relationship of the feldspar group, it usually contains some color, and crystals like this one, which are almost colorless, are very rare.

Oligoclase itself rarely appears on the market, and the quality of the gemstone is barely around 3 CT at most.
Crystals exceeding 5CT, such as those shown here, are quite large.

Moreover, it is clear and high quality.

As you can see in the photo, there are some small inclusions, but this is a very clear crystal for this type of gemstone.

Oligoclase gives off a sharp shine.

I would appreciate it if you could take a look at it.
