My husband who isn't into crystals says "It's cool," and greater praise cannot be spoken... I guess. Straight up though, he's not wrong. It's cool.

Concentric iron circles, with real amethyst crystals. The tear drop crystal in the centre is resin with an iridescent coating to reflect light in a burst of colours. Amethyst known as "the all purpose stone."

Each is unique. The amethysts may appear slightly different in colour from the one photographed. No crystal is ever the same but this is what makes them special. 

Not particularly heavy - it will hang happily from a pushpin.
