A rare stone with mysterious color-changing properties!
Hackmanite 1.70 CT

RECOMMENDED POINTS
This is an impressive hackmanite that mysteriously changes color due to ultraviolet rays.

Hackmanite is a rare stone whose silky purple crystals change to a deep purple color when exposed to ultraviolet light.

Hackmanite was first discovered on the Kola Peninsula in Russia and is named after the Finnish geologist Viktor Hackman.

Hackmanite, a variety of sodalite, has the property of changing color when exposed to ultraviolet light and returning to its original color when the exposure stops, a property that can be repeated over and over again, making it a popular collector's stone.This mysterious property of its dramatic color change when exposed to ultraviolet light is called "photochromism" or "tenebresence."

Unlike ordinary color-change stones, hackmanite changes color when exposed to ultraviolet light and slowly returns to its original color when the exposure is stopped.
This type of hackmanite is basically a mineral stone.

The degree of discoloration varies from crystal to crystal, and it is not an immediate change in color, but rather a gradual, mysterious change in color.

It is a rare crystal created by nature.

Please take your time to enjoy the mysterious color-changing stones.
