15.05 Ct. White Sapphire from Ceylon (Sri Lanka)

This transparent 15.05 carat asscher octagon white sapphire measures 12.75 x 12.57 x 9.63 mm and is presented in a classic asscher cut. The stone exhibits near colorless color intensity and a clarity grade of very very slightly included evaluated at eye level, presenting as eye clean to normal observation. The cut and proportions deliver the characteristic step cut geometry with broad, symmetrical facets that emphasize clarity and depth, and the excellent polish ensures crisp facet junctions and refined light return. Origin is Ceylon Sri Lanka and there has been no enhancement, confirming natural formation and integrity. This sapphire is offered by The Natural Sapphire Company.

Given its substantial carat weight and nearly square asscher octagon outline, this sapphire is exceptionally well suited for custom jewelry applications where presence and geometry matter. The dimensions and depth profile provide a commanding table and pavilion relationship that works effectively in both open prong settings and low bezel mounts, allowing designers to choose either a light maximizing presentation or a protected, contemporary aesthetic. The asscher cut’s symmetry complements architectural designs, making it appropriate for solitaire engagement rings that favor crisp step cut reflections, vintage inspired settings that highlight corner facets, three stone compositions that balance side stones without overwhelming the center, and pendant designs where the stone’s face up size reads large and elegant.

For bespoke projects the stone’s near colorless tone offers versatility with metal choice, pairing harmoniously with platinum for a cool, modern look or with warm yellow or rose gold for subtle contrast that emphasizes facet clarity. The lack of enhancement simplifies decision making for collectors and designers who prioritize natural material characteristics when planning mounting techniques and lighting considerations. In practical terms the 12.75 x 12.57 mm face dimensions translate to a significant visual presence on the finger or neck, while the 9.63 mm depth provides secure girdle engagement for experienced setters. This sapphire presents a refined balance of scale, shape, and optical purity, making it an excellent foundation piece for a custom creation that aims for lasting elegance and technical precision.
