3.67 Ct. White Sapphire Crystal from Ceylon (Sri Lanka)

This specimen is a semi transparent white sapphire weighing 3.67 carats, with exact dimensions of 17.90 x 5.40 x 3.90 millimeters, presented in a various shape that preserves the elongated natural crystal outline. The cutting approach is best described as a rough crystal cut, where the lapidary emphasis is placed on retaining the original growth morphology while selectively trimming and shaping to enhance face up proportions. Rather than imposing a standard brilliant or step faceting scheme, the cutter has respected primary prism orientations and natural terminations, removing only the portions necessary to eliminate matrix and to balance symmetry for practical mounting. The result is an object that reads both as a gem and as a specimen, with proportional length and thickness that make it especially suitable for linear settings and contemporary interpretations of cabochon and freeform bezel work. The overall execution retains the intrinsic silhouette of the raw crystal, while delivering a calibrated piece that will seat securely in bespoke settings.

Clarity is graded as included on an eye level evaluation, which indicates the presence of internal features that are visible without magnification, yet do not preclude good light transmission. In stones of Sri Lankan origin, typical inclusion suites comprise crystalline mineral occlusions, fine acicular inclusions, and healed fissures, all of which contribute to the character of the stone and to internal light scattering. This sapphire is semi transparent, so light diffuses through the body giving a soft, ethereal glow rather than pinpoint brilliance, and the internal features create subtle zones of contrast when viewed from different angles. The surface condition is described as excellent polish, achieved through progressive lapidary work using diamond abrasives at successively finer grits to remove milling marks and to maximize specular reflection on the trimmed faces. Excellent polish on a rough crystal cut requires careful control of rotation speeds and polishing pressure to preserve micro topography introduced by the intentional retention of crystal form.

Color intensity is near colorless, a grade that denotes minimal chromophore absorption across the visible spectrum and a high degree of neutrality to the human eye, with only the faintest hint of warm undertone that is characteristic of many Ceylon sapphires. This neutrality makes the stone highly versatile in design applications, since it will read as white or icy under a variety of lighting conditions, yet still convey the depth and natural variability expected of an untreated gem. Important to collectors and connoisseurs, this gem is offered with no enhancement, which affirms that no thermal diffusion, irradiation, filling, or other laboratory processes have been applied to modify color or clarity. The stated origin is Ceylon Sri Lanka, a provenance with a long history of producing corundum that forms in high grade metamorphic terranes and alluvial gravels, and which often displays the combination of delicate color and lively internal structure seen in this example.

For designers and technically minded buyers The Natural Sapphire Company recommends treating this piece as both a gem and a specimen, selecting settings that showcase the elongated profile and semi transparent body. A low bezel with a recessed channel will protect the edges and emphasize the length, while a custom prong grid or trellis can create optical windows that accentuate translucency and internal structure. Given the included clarity grade, backlighting or open backed mounts can be used deliberately to reveal the internal architecture, while sealed bezels will produce a softer, more diffused appearance. As an untreated Ceylon sapphire with excellent polish and a restrained near colorless tone, this stone is well suited to minimalist modern jewelry, bespoke engagement pieces for those seeking a natural aesthetic, and collectors who appreciate specimens retaining strong crystallographic character. The Natural Sapphire Company stands behind the accuracy of these technical observations and can provide additional imaging and setting consultations to ensure the best presentation of this unique rough crystal cut sapphire.
