Product Description
These optical calcite pieces, also known as Iceland spar, are natural crystals known for their distinctive double refraction effect—when placed over text or objects, they can create a visible doubling of the image.

Each piece varies in clarity, shape, and internal formations, ranging from more transparent to milky white. Their larger size makes them ideal for display, collections, or as a standout natural specimen.

Due to their natural formation, some pieces may have inclusions, internal fractures, or irregular edges, adding to their character.

Optical calcite is often associated with clarity, focus, and energy amplification, making it a popular choice for both its visual properties and symbolic meaning.
