This purple sapphire originates from the gem bearing layers of Ceylon Sri Lanka, a region known for producing corundum with lively hues and strong saturation. In situ the rough displayed a combination of strong chromium driven color response and clear crystalline habit, prompting selective extraction and immediate segregation by our field agents. The initial recovery involved hand sorting at the mine site, followed by primary cleaning with deionized water and mechanical sieving to remove matrix material. Geological provenance informed early decisions, because sapphires from this district often display zonal color distribution and distinct pleochroic behavior, therefore conservative preforming was employed to preserve the most saturated material. Our cutters selected a single piece of rough that would yield a transparent 1.81 carat cushion shape stone, the decision guided by crystal orientation, natural facet planes, and an aim to minimize directional color variation while maximizing weight retention. From mine to parcel, traceability records were maintained, allowing the stone to be tracked through each stage of cutting and finishing, assuring provenance integrity for discerning buyers who value certified origin.
The lapidary stage emphasized a mixed brilliant faceting scheme to balance fire, scintillation, and color saturation, the cutter configuring a faceting model that pairs a modified brilliant crown with a step influenced pavilion to enhance color depth. The finished measurements are 7.15 by 7.04 by 4.42 millimeters, producing a depth percent calculated at 62.3 percent based on the average girdle diameter. This proportion falls within the ideal range for cushion shapes where slightly deeper proportions can intensify color without sacrificing light return, particularly for stones with strong hue. The mixed brilliant cut places emphasis on a well proportioned table to maintain broad flash while the pavillion facets are arranged to direct light back through the crown, producing both broad area color and pinpoint scintillation. Facet symmetry was controlled to tight tolerances to avoid light leakage, and the girdle was finished to an even profile to facilitate secure setting. The intense color intensity is consistent across the table and crown, exhibiting a pure purple hue with balanced tone and saturation, and the stone has not undergone any enhancement, preserving natural optical properties.
Clarity assessment was performed under standard gemological viewing conditions, resulting in a grade of very very slightly included as evaluated at eye level, indicating that the stone is effectively eye clean with only minute internal features visible under magnification. In practical terms this means the gem presents an unencumbered face up appearance, while microscopic inspection reveals fine pinpoint inclusions and occasional negative crystals that do not interfere with light performance. The cutting strategy minimized the visibility of these inclusions by orienting facet junctions and table position to steer attention toward color and brilliancy rather than internal features. Polish quality was assessed on each facet, and the stone received an excellent polish grade, which is evident in the crisp facet junctions and high surface luster. Excellent polish reduces surface diffusion of light and enhances contrast between facet planes, improving both brilliance and the perception of saturation. The combination of high polish, precise facet geometry, and the inherent transparency of the material produces vivid color flashes and a controlled scintillation pattern that is pleasing to the connoisseur eye.
From final inspection the stone was forwarded to The Natural Sapphire Company for retail presentation, entering a final quality control sequence that includes photographic documentation, independent verification of origin, and specialized mounting recommendations for clients. For setting, the ideal context for this cushion purple sapphire is a balance between protection and exposure, a bezel with open gallery or a secure prong setting with low profile crowns will preserve the stone while permitting light interaction through the crown. Designers are advised to consider warm metal tones to subtly enhance the purple, or platinum to offer a modern contrast that emphasizes the stone as a color focal point. Because the sapphire is unheated and unenhanced, it is especially suitable for high value bespoke pieces and for collectors who prioritize natural state gems. Aftercare guidance includes routine cleaning in ultrasonic and steam environments only after consultation, and periodic professional checks to ensure the setting maintains proper security. The Natural Sapphire Company stands behind the documented journey of this 1.81 carat cushion shape purple sapphire, offering provenance records and personalized design services to ensure that this gem moves from market to jewelry as an informed and enduring investment.
