0.80 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing describes one transparent 0.80 carat round blue sapphire, offered by The Natural Sapphire Company. The gem measures 5.84 x 5.88 x 3.08 mm and has been faceted in a mixed brilliant cut. Clarity has been assessed as eye clean when viewed at eye level, the color intensity is classified as medium intense, and the polish on all facets is excellent. Importantly, this sapphire has no enhancement, and its documented origin is Ceylon, Sri Lanka. The combination of a well centered round outline, balanced dimensions, and mixed brilliant faceting produces consistent light return and an even appearance across the crown and pavilion, attributes that are readily apparent in hand viewing and under standard gemological loupe inspection.

Among sapphires of similar weight and shape, this stone is notable for the relative scarcity of its specific combination of size and color. At 0.80 carat, round sapphires are commonly available, however it is comparatively uncommon to encounter a round stone of this size with a medium intense blue tone that is both transparent and eye clean while remaining completely untreated. Many comparable stones in the market will show either a lighter tone, a more heavily included body, or evidence of routine heat treatment to stabilize or enhance color. By contrast, this sapphire presents a naturally achieved medium intense blue that maintains attractive saturation without appearing overly dark for the size, a balance that is prized by collectors and designers seeking a naturally colored center stone that sits well in fine jewelry proportions.

From a cutting and finish perspective the mixed brilliant cut used here enhances both brilliance and perceived size. The dimensions of 5.84 x 5.88 x 3.08 mm yield a shallow to medium depth profile that maximizes spread on the finger and other wear surfaces while retaining appropriate facet relationships for scintillation. The mixed brilliant design blends a faceted crown pattern with a pavilion geometry aimed at returning light to the observer, producing crisp facet junctions and pleasing contrast. The excellent polish contributes to clean facet reflections and minimizes surface interruption, and the eye clean clarity means that under normal visual inspection the table and crown appear free of noticeable inclusions, allowing the color and cut to be experienced without internal distractions.

As an untreated sapphire from Ceylon, Sri Lanka, this gem offers provenance that is meaningful to many buyers and connoisseurs. Ceylon sapphires are frequently sought for their clarity and classic blue hues, and an untreated stone of this specification is a suitable candidate for a fine solitaire, a refined halo design, or a paired setting in artisan jewelry. The Natural Sapphire Company selects stones with attention to optical performance and structural integrity, and this sapphire’s attributes make it a measured choice for both design intent and long term enjoyment. Documentation accompanying the stone will confirm the stated characteristics, including weight, measurements, cut style, clarity grade as eye clean evaluated at eye level, color intensity as medium intense, polish as excellent, absence of enhancement, and origin as Ceylon, Sri Lanka.
