Under bright light, some of these internal features catch subtle flashes of rainbow colour, adding another dimension to an otherwise beautifully clear specimen.\u003c\/p\u003e\n\u003cp\u003eOne of the most fascinating characteristics of Optical Calcite is its strong double refraction. When viewed through a sufficiently clear section, objects or text positioned behind the crystal can appear doubled due to the way light passes through its structure.\u003c\/p\u003e\n\u003cp\u003eAt approximately 45mm, this is a lovely accessible collector specimen and an interesting example of Calcite's natural optical properties.\u003c\/p\u003e\n\u003ch2 class=\"PDq2pG_selectionAnchorContainer\"\u003eAbout Optical Calcite\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/h2\u003e\n\u003cp\u003eOptical Calcite is a particularly transparent form of Calcite, a naturally occurring calcium carbonate mineral.
