Newton and his prism found that that white light is a mix of the three primary colors. Quartz seems to have known it long before! Its crystal structure opens the door to an interesting artistic interpretation of this theory.

How can we not be seduced by mineralogy? I am!

Apparently, it all started like that thousand & thousand years ago. Little dots getting together as one structure to grow as a tall translucent crystal. Quartz is a crystal of many hidden beauties…

Just like cool ice in the middle of a hot summer day, the Quartz geometry has a soothing and refreshing feel. So does the elegant symmetry of its atoms in their unit cell.

– Maban in Australian Aboriginal mythology – Quartz is going to be the mineral of week #34. Regardless of its size or shape, its long prism faces always join at a perfect 60° angle. The Ancient Greeks called it kruos, “icy cold” because they believed the mineral to be a form of super cold ice.

Quartz belongs to the trigonal crystal system – triangular in cross section, and its symmetry is P31/21 or P32/21. The largest documented single crystal of quartz was found near the town of Itapore, Brazil. It measured approximately 6.1×1.5×1.5 meters and weighed more than 44 tonnes.
