2.14 Ct. Peach Sapphire from Ceylon (Sri Lanka)

This specimen from The Natural Sapphire Company is a transparent peach sapphire weighing 2.14 carats, presented in an oval shape with dimensions 9.32 by 7.17 by 3.75 millimeters. The cutting style is faceted, executed as a mixed brilliant cut, and the gem is evaluated as eye clean at standard viewing distance. Color intensity is medium, and the polish is graded excellent. The stone is natural, originating from Ceylon, Sri Lanka, and it has no enhancement. These baseline characteristics define both its visual presence and the optical behavior that produces its distinctive sparkle.

The optical performance of this sapphire arises fundamentally from corundum chemistry and crystallography. Sapphires are crystalline aluminum oxide, corundum, with a trigonal crystal system that establishes a consistent, dense lattice. This lattice produces a high refractive index in the range typical for sapphire, which causes strong bending of incoming light at each facet interface, and significant internal reflection. Although corundum has relatively modest dispersion compared with diamond, the combination of high refractive index and clean internal structure yields intense white light return and well defined flashes of color. Birefringence in corundum is low, which limits double images and supports crisp facet reflections rather than blurred light. Because this specimen is transparent and eye clean, light passes through and reflects within the stone without disruption by inclusions, maximizing the efficiency of light return and enabling the faceting to shape and project the gem s intrinsic brilliance and scintillation.

The mixed brilliant cut and the specific oval proportions in this piece are central to the way the structure is translated into a visible sparkle. The cutter has combined a brilliant pattern on the crown with a modified or stepped pavilion, a configuration that directs and concentrates light back to the observer while also preserving color depth. The oval’s length to width ratio is approximately 1.30, a proportion that encourages broad, lively flashes across the table rather than extremely narrow light lanes. The measured depth is 3.75 millimeters, which corresponds to a depth percentage of about 45.5 percent when related to the average of the length and width. This relatively shallower depth produces a larger apparent surface area and tends to create more expansive flashes and lively surface scintillation, whereas deeper stones often emphasize depth of color at the expense of surface flash. Each facet plane, cut to precise angles, creates multiple internal reflections, and the crown facets disperse and scatter light to the eye while the pavilion facets return that light efficiently, creating the balance of brilliance and contrast. The excellent polish ensures that facet junctions are crisp and reflective, so reflections are sharp and energetic instead of soft or diffuse.

Because this sapphire is untreated, its natural crystal chemistry and color zoning remain intact, and the optical behavior you observe is a direct manifestation of those factors combined with skilled cutting. The medium peach coloration typical of Ceylon material interacts with the internal light dynamics to produce warm, pastel flashes that shift subtly with viewing angle and illumination. The eye clean clarity grade means viewers see uninterrupted pathways for light, so scintillation and sparkle are experienced across the entire gem surface without interruption. Taken together, the inherent physical properties of corundum, the mixed brilliant faceting philosophy, the oval proportioning, and the meticulous polish produce a sparkle that is both broad and lively, with well defined flashes, strong light return, and a natural, soft fire appropriate to sapphire s dispersion characteristics. This balance of optical phenomena is the reason the piece from The Natural Sapphire Company presents a sparkle that is distinct and immediately noticeable when compared to stones that are either heavily treated, poorly cut, or compromised by inclusions.

In practical terms, the result is a versatile, refined center stone suitable for settings that emphasize its oval silhouette and surface brilliance. At 2.14 carats the gem has enough presence to read as an important jewel, while the mixed brilliant cut and eye clean clarity ensure it will perform well in both direct and diffused light. Its Ceylon provenance contributes to the appeal, as Sri Lankan sapphires are known for their attractive pastel tones and fine crystalline structure, which in this case supports both transparency and lively optical response. With no enhancement, the gem retains its natural integrity and long term stability. For those considering the stone for custom work, the combination of dimensions, cut, and polish offers predictable performance in many mounting styles, and The Natural Sapphire Company provides the gemological documentation and expertise to support informed decisions about metal choice, setting depth, and design that will showcase the sapphire s unmatched sparkle.
