The Marble Quarries of Carrara are world famous source of the highest quality carving and building stone. For centuries these Quarries were the first choice for a pure, brilliant Marble. They have also been the source of limpid Quartz crystals found on occasion that are impressive, colorless and perfect. This is a choice example of this sort of Quartz, flawless and transparent, sitting on the white Marble. The largest prism is a right handed Quartz 1.7 CM tall. A good find of these in 2018 yielded a nice selection of top quality pieces which are not very often available. We selected this from the lot of almost 100 pieces as a very good value, esthetic and with the classic presentation.
