Urchin Quartz, also known as Star Quartz or Hollandite Quartz, is a rare and unique variety of quartz that is characterized by tiny black or dark gray inclusions of the mineral Hollandite. These inclusions, which resemble tiny stars or sea urchins, give the quartz its distinctive appearance.
The stone measures 1.2 x .75 x .3 inches and is set in sterling silver. It comes with an 18 inch steel chain.
