Iceland Spar
A transparent optical calcite crystal admired for double refraction, luminous clarity, and refined mineral beauty.
Iceland Spar, also known as optical calcite, is treasured for its remarkable transparency and natural double refraction. When text or objects are viewed through the crystal, they may appear doubled — a beautiful optical effect caused by birefringence. Its clear rhombohedral form makes it a fascinating piece for collectors, study spaces, meditation corners, or anyone drawn to light, perception, and truth.
Why You’ll Love It
Optical Wonder
Famous for double refraction, Iceland Spar can create a doubled image effect when viewed through the crystal.
Clear Calcite Form
Transparent to translucent clarity and rhombohedral structure give each piece a clean, geometric elegance.
Insight Symbolism
Traditionally associated with clarity, perception, truth-seeking, energetic cleansing, and higher awareness.
Meaning & Energy

The Iceland Spar I received was not very well polished and a bit opaque. Double refraction hardly shows.
