0.56 Ct. Spinel from Ceylon (Sri Lanka)

This listing describes a single, transparent 0.56 carat spinel, cut to an emerald shape, with calibrated dimensions of 5.43 x 4.29 x 2.72 millimeters. The stone presents a pinkish purple hue, evaluated as very light color intensity, and carries a clarity grade of very very slightly included as assessed at eye level. The polish is graded excellent, and the material is completely natural with no enhancement reported. The documented origin is Ceylon, Sri Lanka, a source well known for producing spinel material with delicate pastel tones and refined tonal balance. The proportions and finishing of this example reflect intentional lapidary choices that favor optical purity and a restrained, elegant presence rather than overtly saturated color, making it suitable for collectors and designers seeking a refined pastel spinel from a reputable source, represented here by The Natural Gemstone Company.

From a cutting and faceting perspective, the gem is an archetypal emerald cut, employing a step cut philosophy that emphasizes broad, parallel facet planes on both the crown and the pavilion. The measured length to width ratio is approximately one point two seven, producing a slightly elongated rectangular outline that reads as balanced on the finger and in bezel or prong settings. The cut depth, calculated against the mean of length and width, is approximately fifty six percent, a proportion that supports controlled light return while preserving the stone s delicate tone. The emerald step planes create linear flashes and a hall of mirrors effect rather than a high scintillation profile, which is desirable for stones where clarity and color nuances are intended to be the focal attributes. The cutter s execution results in clean facet junctions and symmetry that align the step facets for consistent reflection, and the excellent polish minimizes microabrasions and surface diffusion that could otherwise soften the gem s contrast.

Optically and materially, spinel is an isotropic species, which means that it transmits light uniformly without double refraction, and this specimen follows that behavior, showing consistent coloration and saturation from multiple viewing angles. The isotropic nature, combined with the step cut, produces controlled and coherent internal reflections that reveal the stone s tone evenly, rather than segmenting color into diverse flashes. From a gemological standpoint, spinel exhibits a refractive index in the region of one point seven one eight, and a Mohs hardness of eight, conferring good durability for everyday wear when properly set. Specific gravity for gem spinel typically clusters around three point six, and the species lacks pleochroism and birefringence, characteristics that contribute to the predictability of appearance under varying lighting conditions. The very very slightly included clarity at eye level indicates that inclusions are minimal and do not create significant light obstruction, allowing the light pathways defined by the step facets to remain largely unimpeded.

The combination of the gem s flawless finishing, tasteful proportions, and natural origin enhances its beauty from every angle, because each technical element reinforces the others. The low inclusion profile and excellent polish permit maximum contrast between the broad step facets and the table plane, so the stone reveals crisp mirror relationships and subtle variations in tone across its breadth. The very light pinkish purple color benefits from the emerald cut s planar structure, which distributes that pastel hue evenly and allows the viewer to appreciate the nuance of color shift toward either pink or violet depending on ambient light, without overwhelming saturation. For settings, the measured footprint and corner truncation inherent to the emerald cut recommend four prong or bezel designs that protect the corners and preserve the clean silhouette, and the gem s modest weight and compact dimensions make it an excellent choice for a refined solitaire, a halo center where its soft color will be complemented by accent stones, or a bespoke design where clarity and polish are prioritized. As with all offerings from The Natural Gemstone Company, this spinel is presented with transparent factual description of grade, proportions, and origin, enabling informed selection by connoisseurs and designers who value technical quality and natural provenance.
