0.97 Ct. Bluish Green Sapphire from Ceylon (Sri Lanka)

This cushion shape bluish green sapphire weighs 0.97 carat and measures 5.80 by 5.26 by 3.87 mm, exhibiting a classic weight to dimension relationship that favors face up presence without excessive depth. The stone is fashioned in a mixed brilliant cut, a deliberate cutting strategy that combines the scintillation and light return of brilliant style crown facets with the color windowing control of step style pavilion facets, the result being an object that maximizes apparent color while preserving sparkle under varied lighting. The cutter has optimized the crown and pavilion geometry to balance table size and crown height, yielding a lively table reflection and controlled pavilion reflections that reduce leakage and maintain a bold face up color. The girdle has been carefully finished to avoid unnecessary material loss, and the culet is proportioned to support internal reflections without creating a dark spot. Polish is graded excellent, which is evident in the crisp facet junctions and the smooth facet planes that contribute to superior light performance and precise facet symmetry, qualities that discerning collectors and lapidaries recognize as critical to both beauty and value.

Optically this sapphire presents a medium intense color intensity in a bluish green hue, a tone and saturation combination that is particularly appealing for collectors seeking colors outside the typical pure blue sapphire spectrum. The mixed brilliant faceting enhances this tone by producing micro flashes of blue and green as the stone is rotated, indicating subtle pleochroism typical of corundum, and the even distribution of color across the table suggests a well centered rough orientation during cutting. Clarity is slightly included, evaluated at eye level, a grade that denotes natural internal features visible to the unaided eye but not necessarily detrimental to the gem well being, often providing confirming internal signatures of natural formation. These inclusions are contained and positioned such that they do not dominate the visual experience, and they can serve as identification markers for future certification and resale. The transparency remains very good, and the combination of eye level clarity with excellent polish and refined facet architecture creates a stone that reads visually larger and more luminous than its weight might imply.

The provenance of this sapphire is Ceylon, Sri Lanka, an origin with a long standing reputation for producing sapphires exhibiting lively tones and excellent crystal quality, a geographic attribution that carries both gemological and market significance. Notably this sapphire has no enhancement, a factor of paramount importance when assessing both immediate value and long term appreciation prospects, because untreated corundum from classic sources commands a persistent premium in primary and secondary markets. The Natural Sapphire Company provides full disclosure of origin and treatment status, and that documentation supports confidence in authenticity and allows the buyer to place the stone accurately within the rarefied segment of natural, untreated Sri Lankan material. The cutter here has evidently prioritized retention of natural color and weight over aggressive polishing or heat treatment, a craftsmanship choice that appeals to knowledgeable buyers who understand that the long term capital value of an untreated stone often outperforms similar treated counterparts.

From an investment perspective this 0.97 carat cushion bluish green sapphire represents an attractive balance between rarity and market accessibility, because near one carat weight stones from Ceylon that are untreated and well cut are increasingly sought after by collectors and jewellers alike. The market for secondary color sapphires such as bluish green has shown resilient demand, driven by a preference for unique but wearable hues, and supply constraints on high quality untreated material further support potential appreciation. Key value drivers here are the untreated status, the established origin, the excellent polish, and the skilled mixed brilliant cutting that enhances both face up color and brilliance, attributes that tend to compound value over time as supply tightens and provenance becomes more important to discerning buyers. For investors seeking a tangible asset with intrinsic beauty and the potential for capital growth, this sapphire is a candidate for inclusion in a curated collection, especially when paired with documented provenance from The Natural Sapphire Company, which facilitates future valuation and resale. We recommend retaining the original certification, considering secure storage and insurance, and consulting with our gemological advisors for long term strategies, because well documented untreated sapphires from reputable origins have historically shown steady appreciation and remain a preferred segment within fine colored gem investments.
