0.43 Ct. Purplish Pink Sapphire from Ceylon (Sri Lanka)

This 0.43 carat cushion shape purplish pink sapphire from Ceylon offered by The Natural Sapphire Company is a finely executed example of mixed brilliant faceting combined with classical cushion geometry, the dimensions of 4.27 x 3.70 x 3.16 mm yield a compact pavilion to crown ratio that promotes lively return of light, the mixed brilliant arrangement on the crown provides a balance of scintillation and larger table facets for color saturation, the pavilion facets are faceted to enhance depth and evenness of tone while the excellent polish gives crisp facet junctions and minimal surface abrasion, the stone is transparent with an evaluated clarity of very slightly included at eye level which indicates only minor internal features that do not disrupt the overall brilliance, the color is graded as intense with a purplish pink hue that displays even saturation across the table and pavilion without significant color zoning, the gem is natural with no enhancement, this lack of heat or other treatments preserves the original crystal chemistry and makes it an especially desirable material for collectors and connoisseurs, provenance from Sri Lanka contributes to the stone character, Sri Lankan sapphires are known for clean, vivid tones and this specimen follows that tradition.

From the perspective of durability and suitability for everyday wear this sapphire is corundum, which ranks 9 on the Mohs scale, this places sapphire one ordinal step below diamond at 10 and well above common gemstones such as quartz at 7, the practical implication is that this gem resists abrasion and maintains polish in daily settings, it is suitable for rings and other frequently worn pieces provided the mount is well designed to protect corners and the pavilion, technically the sapphire exhibits refractive index and specific gravity values consistent with corundum which contribute to its brilliance and heft on the finger, minor birefringence is present but is controlled by the cutting orientation to avoid unwanted doubling, for setting recommendations consider secure bezel or prong settings that protect the cushion corners while allowing the crown facets to interact with light, The Natural Sapphire Company certifies the stone as untreated and finely cut, and our cutters have optimized facet alignment to maximize the intense purplish pink color while preserving durability and optical performance.
