Iceland Spar | Optical Calcite | 59 Grams | Rhombohedral | China | SO24 Spodumene Strand Length: 40 cm /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.
