Pink Tourmaline in Quartz Handstones from Madagascar
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).

Hand stones
Hand stones are our largest, tumbled and smoothly polished (precious) stones that often sit very well in the hand, which immediately explains the name. Drummed, this size is also called a palm stone or jumbo stone. Often these stones are extra polished or ground after tumbling for a beautiful end result. Despite this consistency, it remains a natural product, so variations in shape, colour and pattern can always occur. This can vary from one type of stone to another.
Generally, handstones have a size between 4 × 3 × 2 cm and 6 × 5 × 3 cm. Almost all our handstones come from Madagascar, where they are carefully selected and processed. The product photos give a good impression of what to expect. Hand stones are sold per 100 gr (1x), with a minimum order of 500 gr (5x).
