Quartz with cleavelandite
A variety of albite ( Sodium Aluminum Silicate) is often found in association with tourmaline, beryl and other nice minerals, but not so common as inclusions like in this clear quartz. May be confused with calcite or dolomite or other white minerals, but the tiny platy similar to a book is a confirmation of this mineral structure.
It is found in Minas Gerais, Brazil.
