Water Sapphire Iolite

About your companion

Dive into the endless depth of the water sapphire – also known as iolite. With its magical play of colors between blue, violet, and gray, this gemstone resembles the light on calm water surfaces under moonlight. Historically, iolite was revered by the Vikings as the "stone of navigation" – its optical double refraction helped sailors and travelers stay on course, even when the sun was hidden. For hundreds of years, it has helped those who carry it find their own path and walk it with confidence and clear decisions.

Each of our iolites is carefully selected as a raw gemstone and cut with the utmost precision.
