0.84 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.84 carat oval blue sapphire presents a precisely measured profile, with dimensions of 6.24 by 4.47 by 3.59 millimeters, making it an ideal candidate for a variety of fine jewelry settings. The stone has been cut in an elegant mixed brilliant style, where a brilliant cut crown works in concert with a more structured pavilion to balance scintillation and depth of color. The facet junctions are executed with care, and the girdle is consistent, contributing to uniform light return and predictable stability in a bezel or prong mounting. Originating from Ceylon, Sri Lanka, this sapphire demonstrates the island provenance that connoisseurs associate with vibrant, lively blues, and the piece bears the disclosure of heat treatment, a stable enhancement used to optimize color and clarity in natural corundum.

Color sits at the forefront of this sapphire’s appeal, described as a medium light intensity blue that reads as vivid yet delicate under neutral lighting. Ceylon sapphires often display a luminous tone that leans toward cornflower blue, and this specimen exhibits that characteristic with a slightly cool overtone that enhances perceived saturation. The mixed brilliant faceting interacts with the gemstone’s internal color distribution to produce lively flashes of blue across the table and crown facets, and the interplay between pavilion reflections and crown dispersion results in a dynamic visual field when the stone is set. In practical terms this means the gem will stand out in any jewelry setting, catching the eye with a clear blue presence that contrasts beautifully against both warm and cool metal colors.

Clarity has been evaluated at very very slightly included when viewed at eye level, indicating that there are no inclusions readily visible without magnification, and the stone maintains strong transparency and light transmission. Under loupe examination minute internal features affirm natural origin, but they do not compromise brilliance or durability. The excellent polish on both crown and pavilion facets ensures crisp facet junctions, minimal drag lines, and efficient return of incident light. Proportions yield a depth of roughly 67 percent when calculated against the average of length and width, which reinforces a pleasing balance between face up spread and depth of body color. The mixed brilliant approach, with its combination of small star and kite facets above and broader step facets below, produces controlled scintillation and a stable color presence from multiple viewing angles.

At The Natural Sapphire Company we emphasize settings and mounting strategies that maximize the gem’s inherent vibrancy. For the most striking presentation consider a solitaire or three stone ring in a minimal prong setting to allow maximal light penetration, or a halo arrangement to enhance perceived size and to provide a contrasting frame that accentuates the medium light blue. For everyday wear, a low profile bezel can protect the girdle while permitting the eye to focus on the clean table and lively crown reflections. Pairing this sapphire with white gold or platinum will emphasize its cool blue tone, while a touch of warm metal such as yellow gold can create an attractive contrast that makes the color feel more saturated and vivid. Heat treatment is a stable and accepted enhancement for sapphires, and this stone’s treatment has been carefully controlled to produce an even, enduring color that will retain its appearance under normal wear and appropriate care.
