0.90 Ct. Peach Sapphire from Ceylon (Sri Lanka)

This 0.90 carat oval peach sapphire presents precise gemological specifications that will appeal to technical buyers, with exact measurements of 6.80 by 5.39 by 3.09 millimeters, a mixed brilliant cut, and a documented origin of Ceylon Sri Lanka. The mixed brilliant cut combines a brilliant style crown with a carefully faceted pavilion designed to balance fire and overall light return, producing scintillation that reads as controlled and even under direct illumination. The stone is untreated, no enhancement, which preserves original crystal chemistry and natural color distribution, and offers a clear provenance advantage for collectors and connoisseurs who prioritize natural state material. The result is a transparent, lightly colored peach sapphire that reads as a delicate pastel in most lighting environments, consistent with the light color intensity grade reported.

From a color grading perspective this sapphire displays a peach hue that can be interpreted as an admixture of pale pink and warm yellow undertones, with low to light saturation resulting in a soft, pastel appearance rather than a vivid tone. Light intensity in this stone is deliberately subtle, which allows strong facet reflections from the mixed brilliant architecture to dominate the visual effect, producing measured brilliance without overpowering color. Clarity is reported as very slightly included when evaluated at eye level, indicating minor internal features that do not materially affect transparency or overall light performance. The excellent polish noted in the assessment indicates precisely executed facet junctions and smooth facet planes, which contribute to the stone maintaining crisp facet reflections and minimizing surface diffraction losses. The proportions yield a depth of 3.09 millimeters relative to the mean diameter of approximately 6.095 millimeters, producing an effective depth of approximately 50.7 percent, a proportion that favors face up spread and efficient light return in an oval outline.

Technical durability and wearability are central to practical selection, and as a corundum species sapphire this gem has a Mohs hardness of 9, making it one of the hardest gem materials available after diamond which is 10 on the Mohs scale. For comparative context, sapphire at hardness 9 is considerably more resistant to abrasion than commonly used gem materials such as topaz at hardness 8, or quartz at hardness 7, and will maintain facet sharpness and polish under normal daily wear conditions. Hardness alone does not fully define toughness, and corundum typically exhibits good toughness with no true cleavage planes, reducing the risk of catastrophic cleavage under impact, although very sharp blows can still cause chipping. Given these material properties, this sapphire is well suited to rings and other frequently worn jewelry, provided the mounting design protects the girdle and prill edges, and recommended care includes avoiding hard impacts and cleaning with warm water mild detergent and a soft brush rather than ultrasonic cleaning under uncertain settings for untreated material.

From a lapidary and design perspective this 0.90 carat oval presents multiple application possibilities, with its measured dimensions lending themselves to both solitaire settings for minimal metal intrusion and halo or three stone designs where the light pastel peach will benefit from contrasting or complementary side stones. The mixed brilliant faceting strategy is advantageous for bezel or prong mounts because facet reflections remain consistent at varying face up angles, and the moderate depth proportion optimizes finger presence without excessive height that can snag or complicate bezel wraps. Provenance from Sri Lanka Ceylon is a significant factor in valuation and aesthetic expectation, as Ceylon sapphires are known for their range of delicate pastel hues and clean crystal habit, and the untreated nature of this piece enhances its rarity and collector appeal. The Natural Sapphire Company offers this gem with full specification transparency and can advise on mounting options that capitalize on the stone s mixed brilliant cut and excellent polish while protecting its girdle and maximizing light performance.
