2.13 Ct. Purple Spinel from Ceylon (Sri Lanka)

This specimen is a transparent purple spinel of 2.13 carat weight, presented in a classic cushion shape and faceted to a mixed brilliant style, an exemplary choice for a high end gemstone collection. The stone measures 8.62 by 5.97 by 4.65 millimeters, and its proportions yield a depth of approximately sixty three point eight percent relative to the average of its length and width, a proportion that supports strong face up presence without compromising balance. The faceting is executed with a mixed brilliant arrangement, combining a concentrically faceted crown to maximize scintillation with a pavilion geometry tailored to return light efficiently. Origin is Ceylon, Sri Lanka, and no enhancement has been applied, making this a natural, untreated spinel offered by The Natural Gemstone Company, suitable for connoisseurs who prioritize provenance and integrity in their collections.

Color is medium in intensity, presenting a refined purple that reads consistently across the pavilion and crown under standard viewing conditions. The hue shows balanced saturation, enough to convey depth and richness while retaining an elegant clarity and transparency that allow internal light play to be clearly observed. Clarity has been evaluated as very slightly included at eye level, meaning that inclusions are minimal and unobtrusive to the naked eye, and they do not materially interfere with the gem's brilliance or transparency. The polish is excellent, enhancing surface luster and ensuring that facet junctions meet with precision, which in turn supports a lively interplay of brilliance and scintillation when the stone is rotated under light.

From a gemological standpoint, spinel is notable for its single refractive behavior and robust physical properties, which contribute to both its visual appeal and its suitability for wear. Typical refractive index values for spinel fall in the range of approximately one point seven one two to one point seven one eight, and specific gravity values are generally near three point five eight to three point six one, characteristics that underpin the dense, lively feel of the material. On the Mohs hardness scale spinel rates eight, which provides substantial resistance to everyday wear while still permitting professional cutting and finishing by an experienced lapidary. The mixed brilliant cut of this cushion shape has been calibrated to the stone's dimensions to preserve weight while optimizing light performance, and the result is a gemstone that presents a generous face up size for its carat weight and a consistent visual depth.

The documented origin of Ceylon, Sri Lanka, adds contextual value given that Sri Lankan localities have a long established reputation for producing spinel of notable color and clarity, often favored by collectors seeking historic associations as well as quality. The absence of enhancement confirms that the color is wholly natural, an attribute that is increasingly important in primary market valuation and long term collectability. For deployment in a high end collection the stone is appropriate both as a standalone cabinet gem and as the focal point of a bespoke jewelry commission, with settings that emphasize the cushion silhouette and allow light to enter from multiple angles being particularly effective. The Natural Gemstone Company can provide additional gemological documentation upon request, and recommends standard precautions in handling and care, including professional cleaning and periodic inspection of any setting to maintain security and surface condition. This 2.13 carat Ceylon purple spinel embodies a combination of natural origin, precise cutting, and measured clarity that makes it a fitting acquisition for a discerning collector.
