Hackmanite is a very rare form of Sodalite. The mineral composition in Hackmanite has an unique property called reversible photochromism. This means the gemstone actually changes color from the natural dusty blue and purple to neon glow under strong UV light! What a fun necklace to own and to play with!

This necklace offers you both the blue and purple Hackmanite in the popular halfsie design. Two small daisy flower wreaths adorn the front. This necklace has 2 small push-in clasps, which allows you to wear the necklace as is, or with your own connector so you can add a pendant or two. 

Necklace length: 18 inches
Metal: 18K yellow gold
Hackmanite size: 6-7mm approx.
