Description:
Quartz was chosen by the geologist Friedrich Mohs to represent grade 7 in his famous scale of hardness dating back to 1825, and which is still valid nowadays. For a long time it was thought that rose quartz appeared as a massive form, until it was discovered in Brazil in a crystallized form. It is still one of the rarest varieties of quartz.
