This Hematoid Quartz stone is a natural beaut. This stone is a clear quartz crystal that contains hematite limonite which is what brings out the reddish brownish coloring in the geode. Hematiod is great for harmonizing and grounding. It is also said to help with clear thinking so one may solve problems in everyday life situations, it is supposed to help transmit negative energy into positive. Thus this stone is said to represent Grounding and Clarity. I set this Hematoid Quartz on a black genuine handmade leather strap with a silver plated bail. Choker is 12 1/2 to 16 1/2.
