“Black dot quartz” is a term used to describe a variety of quartz that contains visible dark inclusions or spots within the crystal. These inclusions can take various forms and colors, appearing as black, dark brown, or even reddish spots, and they can vary in size and distribution throughout the quartz.
The black dots or inclusions in quartz can be caused by various minerals or materials trapped within the crystal during its formation. Common minerals responsible for these inclusions include tourmaline, hematite, chlorite, or carbon-based materials. These inclusions can form unique patterns or designs within the quartz, adding character and interest to the stone.
These quartz specimens are sometimes sought after for their distinctive appearance, and while they might not be as transparent or as highly valued as clear quartz, they have their own appeal for collectors and individuals interested in unique and unusual gemstone varieties.
