1.51 Ct. Violet Sapphire from Africa

This transparent violet sapphire weighs 1.51 carats and is cut to an oval outline with precise dimensions of 7.45 by 6.09 by 4.11 millimeters, yielding a length to width ratio of approximately 1.22, a proportion that balances face up presence with classic oval elegance. The cutter employed a mixed brilliant facet scheme, combining a modified brilliant crown with a pavilion that integrates both brilliant and step facet elements, a design choice that concentrates scintillation across the table while maintaining broad light return through the pavilion. The depth of four point one one millimeters represents a depth of approximately sixty point seven percent when calculated against the average diameter, a proportion that supports both brilliancy and color saturation without appearing shallow or overly deep. The table is well centered, the facet junctions show precise alignment, and the overall symmetry supports an even distribution of reflected light, making the stone read larger on the finger than raw millimeter dimensions alone might suggest.

Color is described as medium intense violet, a balanced saturation that sits between lavender and true purple, with cool undertones that emphasize clarity and luster rather than heaviness. The mixed brilliant cut was selected to optimize this color intensity, using crown angles and pavilion facet geometry that allow for controlled color zoning and lively return of white light, so that the violet tone remains vibrant under both daylight and artificial illumination. Clarity is graded as very slightly included as evaluated at eye level, with only minor internal features that do not impede transparency or interrupt the flow of light across the table, and these inclusions serve as natural fingerprints of the gem rather than detracting blemishes. The polish is excellent, the facet planes are crisp, and the interaction between polished facets and facet junctions maximizes both scintillation and the perception of depth. Importantly, this sapphire is unenhanced, carrying natural color and structure without heat treatment or other common enhancements, and the stone is documented as originating from Africa, a provenance that informs its crystalline habit and trace element profile.

On the Mohs hardness scale this sapphire, being corundum, rates nine, which places it immediately below diamond at ten and above common alternatives such as topaz at eight and quartz at seven, and well above more fragile gems such as opal which sits in the lower middle range. That hardness confers excellent abrasion resistance, making the stone well suited to daily wear applications including rings, pendants, and bracelets, while its toughness and cleavage characteristics are superior to many colored stones, reducing the risk of chipping under normal wear. For settings that maximize longevity we recommend protective designs such as partial bezels or low profile prongs that shield the girdle and culet from direct impacts, and routine care should consist of gentle warm soapy water and a soft brush, avoiding ultrasonic cleaners if surface reaching fractures are suspected. At The Natural Sapphire Company we document origin and treatment status for our sapphires, and we can provide additional gemological reporting and mounting recommendations tailored to the piece you plan, ensuring that this one point five one carat violet sapphire is appreciated not only for its aesthetic qualities but also for its technical merit and suitability to the intended use.
