RECOMMEND POINT
Mysterious color-changing stone
Enjoy your hackmanite!

Very rare hackmanite.
This time we would like to introduce you to loose stones from Afghanistan.

Hackmanite is characterized by a very high number of inclusions and most specimens are in the opaque class.

For this reason, it is difficult to cut and has many mineral inclusions, making it a rare gemstone even when cut as a cabochon.

However, this is a rare loose stone that has inclusions but still feels transparent.


Hackmanite's characteristic fluorescent color when exposed to ultraviolet light is very unique, and when you shine a UV light on it, you can see a dramatic change to a very deep purple color, as shown in the photo!
Then it slowly goes back to its original color.

Also, if you shine an ultraviolet light on a black background, you can see the unique orange color.

Unique and beautiful hackmanite.
Be sure to collect these rare stones.
