Premium Iolite Graduated 3-4mm Rondelle Beads, 16 Inch Strand
Iolite is the gem-quality, violet-blue variety of the mineral cordierite, , known for its intense trichroic pleochroism, which displays violet-blue, yellow-gray, or colorless tones depending on viewing angle. Used in jewelry (often as a 21st-anniversary gift) and known as "Viking’s Compass," it is highly prized for its color.
