Tourmaline Quartz Pierced Pendant from China

Tourmaline

Tourmaline is a group of borosilicate minerals with a complex chemical composition and a wide variety of colours. It occurs in virtually every colour of the rainbow, including pink, green, blue, black and multi-coloured combinations. This variety makes tourmaline one of the most popular gemstones in the jewellery world.

Tourmaline usually forms in pegmatites and metamorphic rocks. Major deposits include Brazil, Afghanistan, Mozambique, Nigeria and the United States. The chemical formula varies, but a general form is (Ca,K,Na)(Al,Fe,Li,Mg,Mn)₃(Al,Cr,Fe,V)₆(BO₃)₃(Si,Al,B)₆O₁₈(OH,F)₄. The hardness is between 7 and 7.5 on the Mohs scale.

Popular varieties include black tourmaline (schörl), pink tourmaline (rubellite), green tourmaline (verdelite) and watermelon tourmaline (pink interior, green rim).

Pierced Pendants

Pierced pendants are polished and cut (precious) stones with a drill hole, making them easy to wear on a cord or chain. This makes them a popular choice for jewellery. In most cases, the pendants are pierced widthwise, from left to right.

The pierced pendants are available in various shapes and sizes, including drop, oval, point and heart. Some of the range is manufactured in China, while other pendants come from Madagascar. The pierced diameter varies by model and is usually between 2 and 4 mm. We sell the pierced pendants individually, with some having a minimum order of 5 pieces. Unfortunately, we do not currently have any matching cord or chain in our range!
