1.18 Ct. Purple Sapphire from Ceylon (Sri Lanka)

This beautiful transparent purple sapphire from Ceylon offered by The Natural Sapphire Company weighs 1.18 carats, and presents a pleasing round outline with measured dimensions of 6.29 by 6.35 by 4.09 millimeters. It is cut in a mixed brilliant style, combining a faceted crown that follows brilliant principles with a step influenced pavilion that allows for controlled light performance. The clarity is graded as very very slightly included when evaluated at eye level, consistent with high quality natural sapphires, and the polish is excellent, yielding crisp facet junctions and minimal surface disturbance to light passage. The color intensity is described as light, which for Ceylon material reads as an airy yet saturated lavender purple that can appear more vibrant when set against a reflective mounting. Importantly, there has been no enhancement to this stone, a factor that significantly increases its rarity and appeal among discerning buyers who value natural, untreated gemstones. Taken together, the combination of carat weight, provenance, untouched status, and meticulous finishing defines this sapphire as a collector quality gem as well as an elegant option for fine jewelry.

From a gemological perspective the clarity grade of very very slightly included at eye level indicates exceptional transparency to the unaided eye, with only minute inclusions apparent under magnification. These minute features are typical growth or mineral inclusions and serve as natural fingerprints that confirm origin and formation, they do not materially impact durability or the visual performance of the stone. The light color intensity in a Ceylon sapphire is highly desirable for its ability to convey both delicacy and presence, it reflects the classic palate associated with Sri Lankan material, known for its clear, bright hues rather than the deeper velvety tones more typical of some other origins. The combination of high transparency and light color intensity produces an effect where the pavilion facets return controlled flashes of purple and lighter flashes that animate the stone in motion, enhancing perceived size and liveliness. Being corundum, this sapphire has a Mohs hardness of nine, ensuring excellent wearability for everyday jewelry, combined with strong refractive properties that support lively brilliance when the cut and polish are executed with precision.

The mixed brilliant cut of this sapphire is specifically chosen to optimize the inherent optical properties of the rough crystal, balancing fire, brilliance, and color distribution. The stone measures approximately 6.32 millimeters in average diameter, with a depth of 4.09 millimeters, yielding an approximate depth percentage of 64.7 percent, a proportion that sits within the ideal range for round mixed cuts to return light efficiently. The brilliant style crown facets generate strong return of dispersed white light and scintillation, while the pavilion design, by virtue of its tailored angles and facet arrangement, controls the path of light through the body of the stone to enhance color saturation without causing excessive dark areas or windowing. The excellent polish ensures that facet planes remain smooth and reflective, which maximizes specular reflection and improves both brilliance and contrast. In motion the mixed brilliant cut encourages a lively pattern of small bright reflections interspersed with flashes of color, producing a balance between sparkle and the even distribution of purple tones. Precision in symmetry and facet alignment further reduces light leakage and enhances the stone’s ability to return light to the observer, a quality that educated buyers can quantify when comparing stones of similar weight and color.

For the informed buyer, this Ceylon, untreated, 1.18 carat purple sapphire represents an attractive intersection of beauty, rarity, and practical wearability. Origin matters to collectors and jewelers alike, and Sri Lankan sapphires carry a long established pedigree for clarity and bright hue, making them particularly appealing for pieces intended to showcase color under natural lighting. The absence of enhancement elevates the stone on the rarity scale and supports preservation of value over time, since many market premia are applied to natural, unheated sapphires. The dimensions and cut make this gem versatile for bespoke settings, it will sit well in rings, pendants, or earrings where a mixed brilliant profile can be allowed to interact with light, for example an open basket or a low bezel that permits light to enter the pavilion and maximize return. At The Natural Sapphire Company we document origin, provide full disclosure on treatments, and present detailed measurements and images so that scholars, connoisseurs, and confident buyers can assess the gem against objective criteria. If you are selecting a sapphire for both daily wear and long term investment, this piece offers the technical proportions, superior polish, and natural provenance that many educated buyers prioritize when seeking a gemstone with both immediate visual appeal and enduring quality.
