Tanzanite Silver 925 Silver Ring Deep Blue ¥48,000 - Stone Type: Tanzanite - Ring Material: Silver (stamped) - Size: 16 (Japanese size) Excellent condition, rarely used. The other items in the third photo are for size comparison. This is a silver ring featuring "Tanzanite," a highly popular stone from Bizoux and the December birthstone. Most Tanzanite undergoes heat treatment. While this process creates a beautiful blue color, other colors disappear. This Tanzanite, however, boasts a multi-colored blue, unlike the sapphire-like blue, reminiscent of the Tanzanian night sky, with various colors blending together. This "pleochroic" Tanzanite, allowing you to enjoy the nuances of the natural blend of colors, is extremely rare, accounting for less than 0.1% of the Tanzanite mined, and can only be found in the Kilimanjaro region of Tanzania. This ring is made with carefully selected stones that have exceptional transparency and rich color.
