0.86 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing describes one beautiful, transparent blue sapphire from The Natural Sapphire Company, weighing 0.86 carat, in a classic pear shape. The gem measures 8.46 x 4.66 x 3.02 mm, and it has been cut in a mixed brilliant style to maximize internal light performance. Clarity has been evaluated at eye level as very very slightly included, which for a natural sapphire of this color translates to exceptional transparency and clean visual appearance to the naked eye. The color has an intense saturation, showing a vivid, true blue that is balanced across the stone rather than concentrated in pockets, and the polish is reported as excellent. Importantly, this sapphire is reported as no enhancement, and the documented origin is Ceylon, Sri Lanka, a source known for producing sapphires with lively, velvety tones and fine crystalline structure.

From a lapidary and optical perspective, the mixed brilliant cut used for this pear shape is deliberately chosen to enhance the inherent properties of corundum, and to deliver optimized light reflection, contrast, and scintillation. A mixed brilliant cut combines the depth and directional light return of pavilion facets typical of brilliant styles with the elegant outline retention of step or modified facets on other parts of the gem. In this pear cut sapphire, the crown facets and the table have been proportioned to allow light to enter through the larger face up area, scatter across the pavilion facets, and reflect back as uniform blue brilliance rather than as washed out areas or dark windowing. The tapered symmetry of the pear shape creates a graded distribution of light, so the narrower tip concentrates flashes while the broader shoulder displays broader, even color and brightness. This balance between facet geometry and material refractive index ensures that angles are favorable for internal reflection, producing a lively mix of pinpoint scintillation and broader flashes of color that remain visible in everyday light conditions, and the excellent polish further ensures minimal surface diffusion of light, preserving crisp facet junctions and optimum contrast.

For the educated buyer considering provenance, treatment status, and long term value, this sapphire offers a compelling combination of attributes. Ceylon sapphires are prized for their color quality and crystalline clarity, and the reported lack of enhancement increases rarity and desirability, because untreated stones of vivid, intense blue color are less common on the market. The very very slightly included clarity grade at eye level indicates that inclusions are minor, unlikely to affect durability, and often help to confirm natural origin when examined under magnification, adding to the stone s gemological story. At 0.86 carat with the given dimensions, this pear shape is versatile for many settings, from a classic solitaire pendant that showcases the tapered silhouette, to a refined three stone ring that uses the tip orientation to elongate the finger. When set with thoughtfully chosen metal and mounting, the mixed brilliant cut will interact with light from multiple directions, making the stone appear lively in both artificial and natural daylight. At The Natural Sapphire Company we emphasize accurate documentation and responsible sourcing, and this sapphire s combination of intense, even color, expert cutting, excellent polish, untreated status, and Ceylon origin makes it a strong choice for collectors and connoisseurs seeking a natural sapphire that balances everyday wearability with enduring gemological value.
