0.86 Ct. Violet Sapphire from Ceylon (Sri Lanka)

This sapphire is a transparent, oval shaped violet sapphire, weighing 0.86 carat, with precise dimensions of 5.77 by 4.88 by 3.51 millimeters. The stone is a mixed brilliant cut, produced from Ceylon, Sri Lanka, and presented with no enhancement. The clarity grade is very very slightly included, evaluated at eye level, and the stone displays medium color intensity with a balanced violet hue. The polish is excellent, and the overall presentation emphasizes the natural characteristics of the material. The Natural Sapphire Company provides this gem as a single, untreated sapphire, and this listing also references White Opal as an opal type, for customers who may wish to consider complementary pairing or matching accents in multi stone designs.

The mixed brilliant cut is the defining factor in how this sapphire interacts with light, and it has been executed to emphasize both internal reflection and external scintillation. The cut combines a brilliant facet arrangement on the crown with controlled pavilion facet geometry, creating a network of small, angled planes that capture incident light and return it to the viewer as measured brilliance and dynamic flashes. The oval outline naturally lengthens the visual face up area, while the proportions yield an effective depth that is suited to preserving color without sacrificing brightness. With a depth that is approximately sixty six percent of the average diameter, the pavilion planes are angled to induce multiple internal reflections, increasing light retention and reducing light leakage through the girdle. The result is a lively field of light return, where the violet color is seen with consistent saturation across the table, and where flashes of paler and deeper violet appear as the stone moves, driven by the interplay of crown and pavilion facets.

Facet junctions and an excellent polish are especially important in a mixed brilliant cut, because sharp facet edges and smooth facet surfaces maximize the reflection and refraction pathways that produce brilliance and dispersion. In this sapphire, polish quality ensures that light entering the crown is not scattered by surface irregularities, allowing the crown facets to direct light into the pavilion, and for the pavilion facets to reflect it back as focused flashes. The mixed cut also moderates the display of pleochroism that can occur in corundum, producing a harmonious balance between the violet primary hue and lighter violet flashes, rather than isolated windows of color or dark zones. The medium color intensity of this stone benefits from the mixed cut, because the facet arrangement enhances perceived saturation by concentrating color in the table plane while the pavilion depth supports a stable body tone. Because the gem is untreated, the cut becomes the principal tool to manage both color and light behavior, and in this example the cutter has preserved a strong face up presence while maintaining natural color distribution.

Clarity and cutting choices work together to present an eye level clarity described as very very slightly included, evaluated at eye level, which means that inclusions are minimal and do not detract from the overall visual performance. The dense array of small facets in the mixed brilliant style helps to break up and conceal minor inclusions by reflecting adjacent facets across their surfaces, producing scintillation that draws attention to light play rather than internal features. For setting considerations, the gem weight of 0.86 carat and the oval dimensions lend themselves to a variety of mounting styles, including four or six prong settings and bezel treatments that preserve the mixed cut crown while protecting the pavilion. The sapphire’s Ceylon origin contributes to the characteristic clarity and lively medium violet tone associated with material from Sri Lanka, offering a natural and attractive color without any post mining modifications. For those contemplating paired or accent stones, White Opal is a complementary opal type that can provide a soft, luminous contrast to the sapphire’s violet, and The Natural Sapphire Company can advise on matched designs that maintain optical harmony between these two materials.
