10.89 Ct. Aquamarine from Ceylon (Sri Lanka)

This exceptional transparent aquamarine from Ceylon, offered by The Natural Gemstone Company, presents itself as a refined statement of single stone elegance, weighing 10.89 carats, with dimensions of 16.68 by 14.17 by 7.99 millimeters. The oval outline is a classic choice that balances face up presence with versatile proportions, and the mixed brilliant cut enhances both scintillation and table transparency. Origin attribution to Sri Lanka is important for the educated buyer, because Ceylon aquamarines are prized for their clarity and delicate pastel blue tones, a result of the specific geological environment in which they form. This stone is natural and untreated, with no enhancement, which means the color and clarity you see are the result of the original crystallization process, making it more desirable for collectors and connoisseurs who value authenticity and long term value stability.

The clarity grade is very slightly included when evaluated at eye level, a grade that signals minimal internal characteristics which do not detract from the overall visual appeal, and often serve to prove natural origin rather than synthetic manufacture. Under loupe magnification, inclusions are minor and well positioned, allowing uninterrupted light passage and excellent transparency, which is a key contributor to scintillation and brilliance. The polish on this aquamarine is graded excellent, creating crisp facet junctions and mirror like facet planes that maximize return of light. The mixed brilliant cut combines a faceting scheme that produces a lively play of light from the crown and a controlled pavilion faceting plan that optimizes depth and return, this balanced approach gives the stone a vibrant face up appearance while preserving weight in the rough for collectors requiring substantial carat size.

Color in aquamarine is a defining characteristic, and this example displays a light color intensity that reads as a clear, refreshing blue, with cool undertones typical of Ceylon material. For buyers who prefer delicate and elegant blue tones, the light intensity offers versatility in jewelry design, pairing beautifully with both white and yellow metals to alter perceived saturation and warmth. The combination of excellent transparency, excellent polish, and meticulous cutting results in a stone whose flawless quality in presentation enhances its beauty from every angle, each facet acting as a window and a mirror to the internal clarity, color, and luster. From the crown to the pavilion the gem exhibits well executed facet proportions, and when viewed in hand the pavilion depth supports a broad table that allows the light to dance across the oval face, producing a pleasing mix of brilliance and soft blue flashes that change subtly as the viewing angle shifts.

Practical considerations for using this aquamarine in fine jewelry are favorable given its size and proportions, the 16.68 by 14.17 millimeter face up area offers strong presence as a solitaire ring or an elegant pendant focal, and the 7.99 millimeter depth supports secure bezel and prong settings without excessive elevation. For rings intended for frequent wear, a low profile bezel or protective gallery will help preserve the girdle and prevent accidental knocks, whereas for pendants where exposure is lower, a refined prong setting will maximize light entry and display. Because the stone is natural and untreated, it is suitable for buyers seeking investment grade material, and we at The Natural Gemstone Company can provide additional services such as custom design consultation, secure shipping, and laboratory quality reports upon request, ensuring provenance and market transparency for discerning purchasers.
