1 pcs 蓝色, 紫罗兰色 坦桑石 - 7.28 ct - 西班牙宝石学院（IGE）

Natural Tanzanite of striking scale and presence, certified by IGE under report number D-60389 and identified as a natural tanzanite from Tanzania, offered as a transparent pear cut gemstone with a violetish blue colour and a documented weight of 7.28 ct. The report records measurements of 14.07 x 9.47 x 7.62 mm, giving this loose tanzanite a substantial face-up size and elegant teardrop outline that makes it especially suitable for a pendant, statement ring, bespoke jewellery design, high jewellery mounting, or refined coloured gemstone collection. The pear shape gives the stone a graceful balance between a rounded lower body and pointed tip, while the violetish blue colour captures the classic appeal of Tanzanian tanzanite, combining blue, violet, indigo, lavender-blue, bluish purple, and cool pleochroic tones associated with fine zoisite gemstones from Tanzania.
