This optical calcite, offered in its raw, uncut form, brings a small piece of nature into everyday life — an honest, tangible stone that feels calming in the hand. The raw piece keeps the stone's natural edges, fracture surfaces and original look — just as it formed in nature.
About optical calcite
Optical calcite (Iceland spar) is a transparent, colourless calcium carbonate famous for double refraction — a line viewed through it appears doubled. It is a softer stone, with a Mohs hardness of about 3. It typically measures kb. 4–10 cm.
Optical Calcite in tradition
Tradition knows it as a stone of clear sight and possibility; many link it to a conscious shift in perspective. These meanings belong to crystal lore rather than medical fact — the stone's beauty and presence are a value in themselves.
Living with it
Its transparent clarity and refraction make it an intriguing piece to hold; keep it from water and knocks. It also makes a good companion for meditation or quiet moments, and a thoughtful gift for anyone who loves the natural beauty of minerals.
Good to know
As a natural mineral, every piece is unique: colour, size, shape and pattern may differ a little from the photo — which is exactly what makes the stone you receive one of a kind. Wipe it clean with a soft, dry cloth, and avoid prolonged direct sunlight, heat sources and harsh chemicals; keep the softer stones from lasting moisture as well.
