This is a rare specimen with a particularly prominent cat's eye effect. Please consider this valuable blue-colored piece. Tourmaline is a stone that crystallizes in a columnar shape. Striations run down these columns 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 indigo-lite tourmaline color bead with such a cat's eye effect. 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.
