416 Strawberry Quartz – 22g & 40x21x18mm – is fused crystal Quartz that has been enhanced with colour. Fused Quartz is a man-made material manufactured principally from sands. It is non-crystalline, and can be made in a high purity state. The chemical name of fused Quartz is silicon dioxide, or Silica.
Quartz with red inclusions of iron oxide is more rarely found, and is often sold under the name Strawberry Quartz or “Red Fire” Quartz. Some specimens have very fine inclusions that are only visible under magnification, lending the Quartz a more or less uniformly strawberry colour. Others have clearly visible inclusions and may appear as clear Quartz with reddish needles, flakes or spangles.
