Description

This specimen is an outstanding rarity. Tourmalines from Kongo are very hard to obtain and only low quantity was ever on the market. This particular crystal is very gemmy; it has the character and the clarity of glass. It shows light wine red colour with a sharp mint green zoning in the middle. Termination is sharp, all faces are highly lustrous. A small contact along one endpoint is present, no significant damages to report.
