Loose Pear-Cut Natural Tanzanite with IGE Gemological Report
This item is a loose, natural tanzanite gemstone accompanied by a formal identification report from the Instituto Gemologico Español (IGE). The gemstone is faceted in a pear-cut shape, characterized by a rounded end tapering to a single point. According to the document, the stone weighs 17.75 carats and measures 19.71 x 13.31 x 9.56 mm. The color is described as 'violetish blue' with a 'translucent' transparency level. The stone exhibits noticeable internal inclusions and a somewhat milky or cloudy appearance, which may contribute to its translucent (rather than transparent) rating. It is currently housed in a clear protective security seal packet marked with report number D-65417. The documentation specifies the origin as Tanzania and notes an enhancement code of 'F2 - oil,' indicating moderate clarity enhancement. While the physical stone shows a pleasant violet-blue hue typical of the Zoisite variety, the inclusion levels suggest a lower grade than eye-clean specimens. The report is dated March 26, 2024, and includes a verification QR code and the official IGE seal, providing a modern standard for gemological provenance and authentication.
