1.73 Ct. Pinkish Purple Sapphire from Ceylon (Sri Lanka)

This 1.73 carat round pinkish purple sapphire is a superb example of Ceylon corundum that will enhance any high end gemstone collection. The stone measures 6.48 by 6.48 by 4.93 millimeters, with transparent body color and a light color intensity that allows both pink and violet notes to read clearly under natural daylight. The round outline is executed with a mixed brilliant cut, and the overall finish is described as excellent polish. Importantly this sapphire is natural and untreated, with no enhancement, and its origin is Ceylon Sri Lanka. These combined attributes make the gem an authentic and collectible specimen, with provenance and treatment status that are critical to discerning collectors.

The mixed brilliant cut has been executed to emphasize both color and optical performance, combining a brilliant facet scheme on the crown with modified pavilion faceting to control light return and dispersion. The crown faceting pattern creates a lively play of small facets that produce scintillation across the table and crown, while the pavilion arrangement is calibrated to reflect and concentrate light back through the crown without overly diluting the pinkish purple hue. Facet junctions are crisp, symmetry is well controlled, and the girdle is proportioned to facilitate secure setting without compromising optical performance. The excellent polish ensures minimal diffusion at facet planes, so light travels through unimpeded, enhancing both brilliance and the finer violet flashes that are characteristic of this material from Sri Lanka.

Clarity is graded as very slightly included when evaluated at eye level, which for the collector translates to minimal internal features that do not materially interfere with visual appeal or sparkle. The inclusions present are subtle under normal viewing and act more as identifiers of natural origin than as detractors. Under magnification the internal structure provides useful information for gemological study, while to the unaided eye the transparency remains clean and the overall appearance bright. Corundum chemistry confers robust hardness and excellent toughness for everyday wear, so this sapphire is suitable for ring mounting or pendant use. We recommend settings that allow light to pass through the crown, such as open prong or low bezel styles, to maximize the balance of color saturation and brilliance that the cut is designed to showcase.

For the serious collector seeking an exemplar of Ceylon colored corundum, this sapphire represents a rare combination of natural origin, no enhancement, meticulous cutting and a pleasing pinkish purple hue. The Natural Sapphire Company sources and presents gemstones with full attention to geological and lapidary provenance, and this stone is consistent with our standards for fine natural sapphires. We can provide detailed imagery and independent gemological documentation upon request, and we stand ready to advise on setting options that preserve the stone symmetry and maximize aesthetic impact. As a single piece, this mixed brilliant round sapphire will serve as a refined focal point in a curated collection, and as a laboratory of optical and material qualities that connoisseurs appreciate and seek.
