1.23 Ct. Pinkish Purple Spinel from Ceylon (Sri Lanka)

As a gemstone specialist representing The Natural Gemstone Company, I am pleased to present a transparent 1.23 carat round pinkish purple spinel with precise dimensions of 6.71 x 6.71 x 4.18 mm, a faceted stone cut in a mixed brilliant style. The mixed brilliant approach integrates a brilliant facet arrangement on the crown with a modified step or pavilion facet scheme, combining the fire and scintillation of a brilliant cut with the depth and color saturation control afforded by pavilion facetting. This particular spinel exhibits a depth of approximately 62.3 percent based on the supplied dimensions, a proportion that balances face up spread with light return, supporting strong brilliance while preserving color intensity. The table to girdle relationship, crown height, and pavilion angles were executed to industry grade precision, resulting in crisp facet junctions and symmetrical alignment across the round outline. The polish is graded excellent, indicating smooth facet planes and polished facet junctions that minimize light leakage and enhance overall luster. Clarity is graded very slightly included, evaluated at eye level, which in practical terms means inclusions are minor and do not materially interfere with the visual performance of the gem when set and worn.

Color analysis is central to both aesthetic and investment evaluation. This spinel presents a pinkish purple hue with medium color intensity, a tone and saturation combination that creates a pleasing balance between vibrancy and versatility. In spinel grading language, medium intensity often commands strong market interest because it maximizes perceived color without tipping into overly dark tones that reduce brilliance. Spinel is singly refractive and does not exhibit strong pleochroism, offering a stable and consistent face up color under common lighting conditions. The refractive index range for spinel clusters around 1.712 to 1.718, and specific gravity typically falls near 3.58 to 3.61, values that contribute to the gem feeling substantial relative to its size. The absence of enhancement is a critical attribute here, because natural, untreated color in spinel is increasingly scarce and highly prized by collectors. The origin of this stone is Ceylon Sri Lanka, a provenance with a long established reputation for producing high quality spinel specimens, and that origin adds a layer of provenance value for discerning buyers.

From a craftsmanship perspective the mixed brilliant cut on this round spinel has been executed to emphasize both scintillation and color delivery, a technical choice that appeals to connoisseurs who understand the interplay of facet design and optical performance. The crown and pavilion facet schema were calibrated to control dispersion and to direct light back through the table, while maintaining face up color that reads true under daylight and incandescent illumination. Very slightly included clarity at eye level signifies that any internal features are small and well positioned relative to facet junctions, thus they do not disrupt the overall pattern of light return. The excellent polish ensures that surface conditions do not detract from brilliance or introduce abrasion that could accelerate wear issues. The stone hardness of spinel at approximately Mohs 8 renders it robust for daily wear, suitable for ring settings when proper mounting considerations are observed. When assessed by a trained loupe the cut symmetry, facet alignment, and girdle uniformity present no significant deviations, signaling a piece that will integrate well into fine jewelry and retain its visual appeal over long term use.

Investment potential and future appreciation should be evaluated through the lens of rarity, treatment status, provenance, and market dynamics. This 1.23 carat Ceylon spinel ticks multiple boxes that historically correlate with positive valuation trends. Natural untreated spinels, especially those with attractive pink and purple hues from established sources such as Sri Lanka, are in relatively constrained supply compared to more commonly traded gems. The absence of enhancement markedly improves the stone marketability among collectors and investors seeking natural material with documented origin. The mixed brilliant cut enhances face up color while preserving weight, a compromise that often appeals to market segments focused on both aesthetic and resale metrics. Over a five to ten year horizon, factors that can support appreciation include continued demand for colored gemstones as alternative investments, growing consumer awareness of spinel as a distinct collectible category, and the finite nature of high quality untreated material. To further enhance liquidity and likely appreciation potential, I recommend obtaining independent certification from a recognized gemological laboratory, and maintaining provenance documentation from The Natural Gemstone Company. Proper setting, insurance, and conservative pricing relative to comparable auction records will also support long term value preservation. Should you wish, I can provide high resolution images, certificates, and comparative market data to assist in a formal investment appraisal.
