Blue Tourmaline

The product is a rare natural tourmaline crystal with a dark blue colour, originating from Pakistan. This unprocessed and untreated crystal retains its original natural state. Measuring 10.20x7.20x7.30 mm and weighing 5.80 carats, tourmaline comes in a size and mass that allow it to be used either for incorporation into jewellery or as part of a mineral collection. The dark blue colour is specific to this type of tourmaline and reflects the chemical composition of the crystal, with no changes brought about by external treatments. The fact that it is untreated ensures its purity and authenticity. It is a fairly rare crystal; blue tourmalines are being mined in small numbers over time. Its provenance in Pakistan contributes to the geological context and value of the crystal, given that the country's regions are renowned for their tourmaline resources.
