This pale calcite plays a neat trick with light.
Optical calcite, often called Iceland spar, is a clear-to-milky calcite with a blocky shape. It has a soft waxy shine and faint natural lines and clouding inside. Known for double refraction, it can make words or edges look doubled when you look through it.
People love it because it feels like a little science lesson you can hold. Some folks keep it on a desk or altar for clarity, focus, or just to stare at when they need a reset.
How to use it
- Hold it up to text and watch the doubling effect
- Keep it on a desk as a curiosity piece
- Place it where light can pass through it
- Gift it to a geology or crystal fan
Care: Calcite is fairly soft, so keep it away from knocks and store it separately from harder stones.
The details
- Stone: Calcite
- Weight: 60g to 140g
