0.56 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.56 carat oval blue sapphire from Ceylon Sri Lanka presents a meticulous balance of size and presence, with exact measurements of 5.16 by 4.24 by 2.58 millimetres, making it an excellent candidate for precision settings where proportion and profile matter, and The Natural Sapphire Company offers this gem as a well documented example of island provenance and classical corundum character, the stone is transparent with a dark color intensity that reads as deep velvety blue under typical viewing conditions, its clarity grade is recorded as very very slightly included evaluated at eye level indicating that inclusions are minimal and do not detract from the overall visual depth, the stone has been heat treated according to trade standard practice to optimize color saturation and structural clarity, and the surface finish is listed as excellent polish which enhances the vitreous lustre inherent to corundum.

The cutting style is a mixed brilliant configuration combining a faceted brilliant crown with a calibrated pavilion that incorporates step or modified facets, this approach preserves table brilliance while enhancing color depth and contrast through controlled light return, with the oval outline and the given dimensions the pavilion depth at 2.58 millimetres yields a proportional depth of approximately 55 percent relative to the average diameter which is within the preferred range for balanced light performance, the crown faceting has been executed to generate dispersed scintillation across the table and shoulders while the pavilion facet architecture limits windowing and promotes a concentrated blue core, the result is a visually stable face up appearance with lively flashes on movement and a deep saturated tone when viewed face on, the mixed brilliant geometry also supports predictable symmetry when set in bezel or pronged mountings, and the excellent polish ensures that facet junctions and planes remain crisp which maximizes specular reflection and perceived clarity.

From a material science perspective the gem benefits from the inherent properties of corundum, including a refractive index in the range typical for sapphire which produces notable brilliance and a low dispersion value which emphasizes tone and saturation rather than fire, the Mohs hardness of nine guarantees high resistance to abrasion making this 0.56 carat oval appropriate for daily wear with conventional care, the heat treatment applied is a stable enhancement that has long been accepted in the gem trade and it refines the absorption bands responsible for blue coloration without compromising structural integrity, the clarity characterization of very very slightly included evaluated at eye level denotes that any internal features are small and generally not apparent without magnification at typical viewing distances, in many Ceylon sapphires such features can include fine rutile needles or minute mineral inclusions that contribute to natural origin verification, the combination of dark color intensity and minimal inclusions produces a strong face up presence while retaining the durable properties that make sapphire desirable for heirloom quality jewellery.

In terms of practical versatility this oval 0.56 carat sapphire transitions equally well between understated casual pieces and refined formal designs, at these dimensions the gem functions beautifully as a solitaire in a low profile ring where the mixed brilliant cut emphasizes scintillation and color, in a halo configuration the deep blue center is framed to increase perceived size and visual contrast for evening wear, a bezel mount offers a contemporary, secure option for lifestyle wear while preserving the elegant profile required for daily use, the stone also adapts to delicate pendant and stud earring applications where measured proportions and excellent polish ensure pleasing light return without overpowering scale, given the proven durability of corundum and the stable nature of heat treatment, maintenance is straightforward, routine cleaning with warm soapy water and a soft brush preserves surface condition and lustre, and for customers seeking assurances The Natural Sapphire Company can provide detailed notes on origin, treatment, and cutting characteristics upon request to support informed selection and bespoke setting decisions.
