Viking Sunstones (Iceland Spar / Optical Calcite)

Viking Sunstones, also known as Iceland Spar or optical calcite, are a clear, double-refractive form of calcite (CaCO₃) historically believed to be used by Viking navigators to locate the sun on cloudy days. These naturally occurring crystals split light into two rays, allowing ancient mariners to detect the sun’s position even in overcast skies or twilight. 

Geologically, Iceland Spar forms in sedimentary environments, often in limestone caves or hydrothermal veins. Its high clarity and optical qualities make it a fascinating mineral for both scientific study and metaphysical exploration.

Metaphysically, Viking Sunstones are associated with clarity, insight, and truth. They’re believed to enhance vision, both physical and intuitive, making them powerful allies for those seeking direction, uncovering hidden truths, or navigating uncertainty. They resonate with the third eye and crown chakras, aiding focus, intention-setting, and spiritual alignment.

A unique addition to any collection, these luminous stones are as legendary as the seafarers who once relied on them.
