Description: This is a large colorless Quartz with a red transparent spot inside.
The color is caused by Hematite that precipitated in a quartz fissure. The material is called Hematoid Quartz, or Quartz with epigenetic inclusions.
This stone has been featured in the Journal of Gemmology, Volume 35, No. 6/2007, page 486. It weighs 103 carats.
The red color is transparent but when viewed with a polariscope, you can see the radial crystallization textures in the Hematite.
( photos 3, 4, 5 ) This is my largest piece of this material.
