Mysterious color change!
Hackmanite 1.37CT

RECOMMEND POINT
This is a rare stone that reacts to ultraviolet light.

This plump cabochon crystal creates a gradual color change unique to gemstones!

We have prepared rare hackmanite from Mogok, Burma that will make you feel the mystery of nature! It has the property of changing color when irradiated with ultraviolet rays and returning to its original color when the irradiation is stopped.
It is a popular collector's stone because it repeats itself over and over again. Hackmanite was first discovered on the Kola Peninsula in Russia.
It is named after the Finnish petrologist Victor Hackman. Hackmanite, a variant of sodalite, has the property of changing color when exposed to ultraviolet rays and returning to its original color when the exposure is stopped, and this process is repeated over and over again.
This stone is popular as a collector's stone, and its mysterious property of dramatically changing color when exposed to ultraviolet light is called "fatochromism."

Rather than a sudden color change, Hackmanite delights the eye with a gradual change in color when exposed to sunlight.

The color gradually changes to reddish-purple,
I would like you to see the progress along the way.
In addition, the color after discoloration has a huge gap from the ground color, making this Hackmanite a sight to behold! This is a stone that you should take your time to enjoy the mysterious color changes created by nature!
