1.12 Ct. Greenish Blue Spinel from Ceylon (Sri Lanka)

This one point one two carat cushion shape greenish blue spinel presents a precise set of gemological attributes that will appeal to discerning buyers, the weight is 1.12 carat, the outline is a classic cushion with dimensions of 6.83 by 5.22 by 3.48 millimeters, the cutting style is faceted, executed as a mixed brilliant cut, the clarity grade is very slightly included when evaluated at eye level, the color intensity is rated intense, the polish is excellent, the stone is unenhanced, and the origin is Ceylon Sri Lanka, The Natural Gemstone Company presents this stone with full disclosure of its provenance and treatment status. The balance of weight and dimensions yields a compact yet substantial presence suitable for a variety of settings, the greenish blue hue is saturated enough to read vividly in both natural and artificial light, and the absence of enhancement preserves the natural crystal chemistry and long term collector value. The clarity profile, described as very slightly included at eye level, indicates inclusions are minimal and do not disrupt the optical performance or detract from the face up color, the eye level grading communicates what a jeweler or a client will experience without magnification, which is an important reference for both aesthetic and investment appraisal.

The mixed brilliant cut employed on this cushion is a deliberate compromise between optical performance and color presentation, the crown exhibits a brilliant facet arrangement designed to maximize scintillation, while the pavilion shows modified facets that deepen the color without sacrificing return of light, this combination produces lively brilliance across the table and well controlled color zoning toward the pavilion, the cut proportions are favorable, with an overall depth of 3.48 millimeters relative to the average of length and width that produces a depth percent of about 57.7 percent, this depth proportion sits within an optimal range for cushion cut spinels where light return and color saturation are balanced, the table and crown angles have been calibrated to avoid excessive darkness or washed out areas, symmetry and facet alignment are precise, the girdle is finished to maintain a robust setting margin, and the culet is proportioned to prevent light leakage at the heart of the pavilion, the excellent polish enhances facet crispness and allows the spinel to display both flash and a stable body color, these cutting and finishing choices are indicative of experienced lapidary work that targets both aesthetic appeal and market value.

From an optical and material standpoint this greenish blue spinel exhibits properties that support both wearability and long term value, spinel is isotropic and singly refractive which means it lacks pleochroism, the absence of pleochroism contributes to even color distribution across different viewing angles, the typical refractive index range for gem spinel centers near 1.718 which yields a lively gemmological response between brilliance and depth, the specific gravity of spinel is around 3.60 which gives a satisfying heft relative to size, and the Mohs hardness of 8.0 provides good resistance to abrasion and practical suitability for everyday jewelry, the combination of durability and stable optical properties makes spinel a reliable choice for collectors who intend to wear their gemstones or to pass them to future generations, the intense natural color from Ceylon Sri Lanka is particularly desirable, Sri Lankan spinels have a long historical market presence and are recognized for clean crystal growth and attractive hues, the no enhancement status preserves geological authenticity and is a key factor when evaluating potential for appreciation.

As an investment grade single stone this 1.12 carat cushion greenish blue spinel offers a compelling mix of scarcity, provenance, and quality driven attributes that support future appreciation in value, market demand for fine, natural colored gemstones has broadened beyond traditional staples, collectors and investors increasingly seek well cut, untreated stones with established origin, Ceylon Sri Lanka origin carries a premium in many trading centers, the intense color and excellent polish reduce the need for reworking and enhance immediate marketability, while the very slightly included clarity at eye level signals collector grade quality that is less vulnerable to downward price adjustments related to clarity, long term appreciation will be influenced by global supply constraints, responsible sourcing practices, and shifting demand from private collectors and institutional buyers, spinel supply is finite and high quality, untreated material from known localities is relatively uncommon compared with more widely mined gem species, these supply dynamics combined with rising awareness of spinel in auctions and high end jewelers indicate favorable conditions for value retention and appreciation over time. To optimize both enjoyment and investment outcomes The Natural Gemstone Company recommends documentation of this stone with a reputable independent laboratory report, secure storage or placement in high quality jewelry, proper insurance, and provenance records, our assurance of origin and no enhancement status aligns this gemstone with the traits collectors prioritize when building a portfolio of tangible assets, this cushion greenish blue spinel is therefore positioned as both an exquisite jewelry center stone and a specialized investment item, the combination of technical excellence in cut and polish, the intense natural color, the minimal visible inclusions, and the Ceylon origin create a profile that is likely to be favorably received by connoisseurs and investors alike.
