Many tourmalines are pleochroic, which means they can show different colors depending on the angle or type of light. It’s like having a gem that looks slightly different each time you look at it, adding to its charm.

With a hardness rating of 7 to 7.5 on the Mohs scale, tourmaline is tough enough for everyday wear but still has the beautiful transparency that makes gemstones sparkle. So, it’s a perfect mix of beauty and durability!

Discovered in the late 1980s in Brazil, Paraíba tourmalines are prized for their neon blue-green hues, attributed to trace amounts of copper.
