This is a rare specimen with a particularly prominent cat's eye effect. Please consider this valuable green-colored piece. Tourmaline is a stone that crystallizes in a columnar form. Lines run down these columns like a curtain. These are called tubular inclusions or tube 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 green-colored cat's eye tourmaline bead. The transparency is somewhat subdued due to the prominence of the cat's eye, but the cat's eye effect is clearly visible. Please consider this uncompromising grade.
