Clear Calcite Raw Clear calcite, also known as optical calcite or Iceland spar, has a rich history dating back centuries. Its origin can be traced to various regions around the world, including Iceland, the United States, Mexico, China, and Brazil.Historically, clear calcite was used as a natural optical device due to its unique optical properties. In the 17th century, it played a significant role in the development of early microscopes and telescopes. Sir Isaac Newton famously used clear calcite crystals to investigate the properties of light and color, contributing to the field of optics.Appearance-wise, clear calcite typically forms as transparent, colorless crystals with a glassy to vitreous luster. It belongs to the calcite mineral group and shares the same chemical composition as other varieties of calcite, such as orange calcite or green calcite. However, what sets clear calcite apart is its remarkable double refraction property, where incoming light is split into two separate rays. This optical phenomenon allows objects viewed through clear calcite to appear doubled or shifted when observed from different angles.Clear calcite has also been valued for its metaphysical properties, believed by some to enhance clarity, insight, and spiritual growth. Its association with the Crown Chakra makes it a popular choice for meditation and spiritual practices aimed at connecting with higher realms of consciousness.
