Rough Black Tourmaline VG382

Material: Black Tourmaline
Size: Varies
Shape: Rough

1. History

Black tourmaline, mineralogically known as schorl, was only recognised as a distinct mineral species in the 18th century, having previously been confused with other gemstones in Europe; the word tourmaline comes from the Sinhalese term turmali, meaning "mixed-colour gem". Because the black variety can develop pyroelectric and piezoelectric effects, it has been used not only in jewellery but also in pressure- and temperature-related instrument parts, while in folk tradition it has long served as a protective, grounding stone believed to deflect negative energy.

2. Origin

Black tourmaline is found in Brazil, Pakistan, Afghanistan, Madagascar, the United States, Mozambique and Nigeria, with large crystals from Brazil and Pakistan being especially common in the collectors' market. This item is sold in the rough state; the product page lists the material as Black Tourmaline, the size as "Varies" and the shape as Rough, meaning the stones keep their natural crystal prisms and broken faces without polishing.

3. Usage

Rough black tourmaline is normally used as a display specimen, a fixed stone in crystal grids, or as part of feng shui and cleansing arrangements, and it is often placed near doorways, on a desk or beside electronic devices; because it is unpolished, it is better suited to display and placement than to being worn against the skin. Natural prisms usually show parallel lengthwise striations and crystal faces, which are best shown on a wooden tray or a light cloth and are easy to group by size for retail display.

4. Benefits & Suitable For

In common crystal usage, black tourmaline is regarded as strongly grounding and protective, said to help steady the emotions, ease anxiety and stress and to "shield" against the feeling of electromagnetic radiation (EMF) from electronic devices; it is therefore often recommended for people who spend long hours on computers and phones, who work under pressure, or who are easily affected by other people's moods. For crystal collectors, home and office styling, and anyone wanting a guardian-type display stone, rough black tourmaline is a familiar and practical choice.
