Check out the mysterious color change Hackmanite 1.45CT

RECOMMEND POINT
This gemstone has a very rare effect of changing color due to ultraviolet rays.

Hackmanite has the property of changing color when exposed to ultraviolet light and returning to its original color when the exposure is stopped.

We would like to introduce you to the rare Hackmanite from Mogok, Burma, which is popular as a collector's stone because it is repeated 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, making it a popular collector's stone.

This mysterious property of dramatically changing color when exposed to ultraviolet light is called "fatochromism."

The plump round cabochon crystal is normally blue in color, but when exposed to UV light, it changes to a beautiful purple.

Even sunlight changes gradually over time, and UV light changes depending on the wavelength and intensity, so why not observe it patiently?

Also, unlike gemstones that change color, the degree of discoloration varies from individual to individual, and the charm of this gemstone is its mysterious fatochromism, where the color gradually changes, rather than a sudden change in color.

Please experience the mysteries of the earth at hand!
