This is a rare specimen with a particularly prominent cat's eye effect. Please consider this valuable piece with its blue-green color. Tourmaline is a stone that crystallizes in a columnar shape. It has striations running down the column like a bamboo blind. These are called tubular inclusions, and similar lines can be seen in kunzite and topaz. When a raw stone with strong striations is processed into round beads, it creates tourmaline beads with a strong cat's eye effect. This time, it's a rare blue-green colored cat's eye tourmaline bead. The transparency is somewhat subdued due to the prominence of the cat's eye, but in return, the cat's eye effect is clearly visible. Please consider this uncompromising grade.
