Quartz – Minas Gerais, Brazil

Very fine quartz specimen featuring numerous crystals growing together along a parallel growth axis. The crystals form a dense and well-structured group, with numerous terminations clearly visible at the ends.

The quartz is completely colourless, with excellent transparency to translucency depending on the areas. The crystal faces are nicely lustrous, and light passes extensively through the crystals, revealing their internal structure and successive growth patterns.

Only one termination shows minor damage; the rest of the specimen is in very good condition.

8 x 8 x 0,7 cm

Highlights of this specimen:

- Numerous quartz crystals developed along a parallel growth axis
- Numerous visible terminations at the ends
- Good lustre on the crystal face

For information :

- Minas Gerais is one of Brazil's major quartz-producing regions and has yielded a remarkable diversity of quartz crystallizations over the years.
