A transparent optical calcite crystal admired for double refraction, luminous clarity, and refined mineral beauty.
Iceland Spar, also known as optical calcite, is treasured for its remarkable transparency and natural double refraction. When text or objects are viewed through the crystal, they may appear doubled — a beautiful optical effect caused by birefringence. Its clear rhombohedral form makes it a fascinating piece for collectors, study spaces, meditation corners, or anyone drawn to light, perception, and truth.
