Parting Planes Ruby Appraisal

200 Carat Untreated Red Ruby Parting Planes Pear Shape

This item is identified as a large, untreated red ruby, specifically described as having 'parting planes' and a 'pear shape.' The stone exhibits a deep, reddish-purple hue, consistent with natural ruby coloration, particularly for unheated specimens that may show variations in color saturation and clarity. Its form is definitively pear-shaped, wider at one end and tapering to a point at the other, a classic and desirable gemstone cut. The surface of the ruby appears to have multiple facets, indicating it has been cut and polished to enhance its brilliance, though the reflections within the stone suggest internal characteristics or inclusions, possibly related to the 'parting planes' mentioned. These parting planes are typically structural weaknesses or natural cleavages within the crystal, which can affect its durability and how light interacts with it. The overall polish of the facets seems good, reflecting ambient light. There are no obvious large chips or cracks visible from the image, but specific surface abrasions or minor scratches cannot be entirely ruled out without closer inspection. The deep red color, characteristic of rubies, is well-represented, and the size, stated as 200 carats, indicates a substantial and significant gemstone. The 'untreated' designation is crucial, suggesting it has not undergone heat treatment or other common enhancements, which typically adds to its rarity and value. The craftsmanship of the cut appears to be to a reasonable standard for such a large stone, aiming to maximize its visual appeal while retaining its substantial carat weight. The stone's substantial size and untreated nature make it a remarkable and potentially valuable specimen.
