A rare color change stone!
Hackmanite 0.54CT

RECOMMEND POINT
A very rare transparent stone among hackmanite.
Enjoy this miracle of nature!

Hackmanite has the unique property of changing color when exposed to ultraviolet light.

As collectors may know, hackmanite is a rare stone.

Additionally, the majority of specimens in this class are opaque and characterized by a high degree of inclusions.

For this reason, it is difficult to cut and the only level of gemstone is whether it has a cabochon or not.

Hackmanite with this kind of transparency and faceted cut is an extremely rare stone that is rarely seen on the market.

Even if you search on the Internet, you will quickly understand how rare gem-quality hackmanite is.

Our store has offered several faceted cut hackmanites in the past, but the quantities available are still overwhelmingly smaller than major gemstones such as rubies and sapphires.

Hackmanite is characterized by its spectacular fluorescence when exposed to ultraviolet light, 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.
