*Please note all loose gemstones are sold on behalf of a third-party wholesaler and pricing is therefore linked to the US$. Regular price updates are performed in order to accommodate fluctuations in the exchange rate and may be carried out without prior notice. Dispatch on loose gemstones will take place 2 working days after purchase to allow for shipping from the supplier to my studio. I do regular inventory updates with them to ensure accuracy, but since these stones are also offered for sale to other jewellery designers, it may happen that a particular stone is no longer available at the time of purchase. In such a case you will receive the opportunity to change your order or a full refund.

From the Sinhalese name turamali, which is thought to mean “stone with mixed colours.”
Some tourmaline crystals exhibit colour zoning from one end to the next, in others the colour is zoned from the outer surfaces inward. When these crystals present colour zoning from green outside to pink inside, they are referred to as watermelon tourmaline. Most crystals display at least some colour zoning and therefore it is a popular practice to cut these stones in long shapes in order to display this characteristic.
The colour of tourmaline can be improved by heat treatment although gamma-irradiation treatments may fade over time.
Please note: We take great care to ensure that the photographs are an accurate representation of the actual stone, but due to differences in screen quality and resolution, and the fact that the colour of a gemstone is dependent on the type of light it is viewed in, some variation is possible.
