Iceland Spar, also known as optical calcite, is a clear, transparent variety of calcite famous for its unique optical property called double refraction. When you place the crystal over text or an image, it appears doubled — a visual effect that occurs because light splits into two rays as it passes through the crystal. This fascinating trait made Iceland spar historically important in early optical instruments and scientific studies, including navigation and the development of polarizing microscopes.
It’s typically colorless or very lightly tinted and forms naturally in sharp, rhombohedral shapes. High-quality Iceland spar is most famously found in Iceland, though it also occurs in places like Mexico, the U.S., and China.
Iceland Spar (optical calcite) is often associated with clarity, insight, and truth. Because of its double refraction property, some see it as a symbol of seeing beyond surface appearances — helping to highlight different perspectives or reveal hidden aspects of a situation. It's thought to support clear thinking and honest communication, making it a favorite for meditation or decision-making spaces.
