This is a very fine cuprian mint green tourmaline from Mozambique. Cuprian means that the tourmaline is copper-bearing and is very similar in nature to the highly prized Paraiba tourmaline from Brazil which is also copper-bearing. These cuprian tourmalines are very highly sort after, both for their colour and their rarity. They come in a range of colors, usually in the blue and green hues. This one is a very lovely minty green colour and it is an ideal size and shape for any jewellery setting.
