1.73 Ct. Pink Sapphire from Ceylon (Sri Lanka)

This 1.73 carat cushion shape pink sapphire from The Natural Sapphire Company is presented with precise gemological detail to satisfy discerning buyers, it measures 9.37 by 6.14 by 3.26 millimeters, it is an elongated cushion with a length to width ratio of approximately 1.53 which creates an elegant rectangular cushion outline, the cutting style is a mixed brilliant which combines a traditional brilliant crown with a pavilion that integrates both step and brilliant facets to balance fire with color saturation, the clarity has been evaluated as very slightly included at eye level which means the stone reads clean to the naked eye while retaining minute natural inclusions under magnification, the color is described as medium intense pink which yields a vivid face up appearance without tipping into overly dark tone, the polish is excellent ensuring crisp facet junctions and superior surface luster, importantly there has been no enhancement, the origin is Ceylon, Sri Lanka which is renowned for producing pink sapphires with lively tone and attractive saturation, the gem is transparent and free of treatment which is a primary value driver for collectors and connoisseurs.

From a cutting and craftsmanship perspective this sapphire exemplifies considered proportioning and facet architecture, the mixed brilliant cut employed here places a moderately sized table to optimize face up brightness while the crown facets are cut to produce controlled dispersion, the pavilion combines step facets near the girdle with smaller brilliant facets toward the culet which further enhances scintillation and internal light return, facet symmetry is consistent across the stone which minimizes light leakage and creates strong contrast patterning when the gem is rotated, the excellent polish reduces surface scattering and increases apparent transparency, the shallow depth relative to average diameter produces a generous face up spread for its carat weight which is particularly valuable for those selecting stones for rings where face up presence is critical, the girdle has been finished to functional proportions to allow secure setting while preserving weight, overall the lapidary decisions reflect a priority on maximizing visible color and brilliance within the natural crystal morphology.

On a gemological level this sapphire exhibits the physical properties expected of natural corundum, the refractive index falls within the standard range for sapphire which produces bright internal reflection and good brilliance, birefringence is low but measurable which can contribute to subtle doubling of facet edges under high magnification and confirms single crystal corundum structure, pleochroism is evident in many pink sapphires and this specimen shows variation in tone when observed along different crystallographic axes, the hardness of corundum at Mohs nine delivers excellent durability for everyday wear and allows the gem to be set in a variety of mounting styles without high risk of abrasion, the very slightly included clarity grade indicates small natural features such as pinpoint crystals or faint silk that act as fingerprint characteristics of natural formation, these inclusions are often used by gemmologists to distinguish natural sapphires from synthetic material which typically presents with different growth signatures, because this stone is unenhanced and originates from Sri Lanka its natural color profile and internal features are intact, making it attractive to collectors who prioritize untreated provenance.

When contrasted with lab grown sapphires the distinctions that favor a natural, untreated Ceylon stone become clear, lab grown corundum offers excellent value for color and clarity with highly consistent hues and very low inclusion counts, they provide a reliable option for fashion jewelry and for buyers prioritizing price per carat, however lab grown material lacks the natural growth history and the rarity premium associated with an untreated natural sapphire, natural untreated stones such as this pink sapphire command higher long term demand because they combine provenance, unique inclusion fingerprints, and the market preference for naturally formed gemstones, moreover the absence of enhancement in this specimen increases its rarity relative to the majority of commercial pink sapphires which often receive heat treatment to optimize color, for buyers considering investment or heirloom pieces the natural, unheated origin from Ceylon, Sri Lanka supports long term value retention and collectability, at The Natural Sapphire Company we can provide detailed imagery, expert gemological commentary, and, upon request, independent laboratory documentation to verify natural origin and treatment status, we also offer guidance on optimal settings to protect the stone and to maximize visual performance, for clients who appreciate the subtle but important distinctions between natural and lab grown corundum this untreated Ceylon pink sapphire represents a technically refined, gemologically verifiable choice that combines classical durability with the aesthetic of a naturally formed, vividly pink sapphire.
