0.61 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

This offering from The Natural Sapphire Company is a transparent 0.61 carat, round shape sapphire, presented in a faceted mixed brilliant cut, with dimensions of 5.29 by 5.28 by 3.05 mm. The gem shows bi color characteristics, often referred to as parti, and displays a light overall color intensity that shifts subtly with viewing angle and lighting conditions. Clarity is graded as very slightly included, evaluated at eye level, and the piece exhibits an excellent polish that enhances its surface finish and the optical return from the table and crown facets. No enhancement has been applied to this sapphire, and its documented origin is Ceylon, Sri Lanka, a source well regarded for producing sapphires with fine crystalline growth features and natural color variation.

The bi color quality of this sapphire is an intrinsic attribute that contributes to its visual interest and individuality, with two tones present that can be appreciated as soft, complementary zones rather than stark bands. In controlled lighting the lighter tonality reads as a pale yellow, while the cooler zone appears as a delicate blue gray, creating a harmonious parti effect that varies with rotation and tilt. The mixed brilliant cut, combining a faceted crown with a pavilion designed for optimal light return, helps to distribute these color zones without creating abrupt color separation, preserving the gem as a single harmonious element. Light intensity being described as light indicates a gentle saturation, which in this stone allows both color tones to remain apparent without dominating the stone clarity or brilliance.

Internal characteristics of this sapphire serve as natural inclusions that function as unique identifiers, and as such they are part of the stone provenance and story. The very slightly included clarity grade indicates small, discrete features that are visible at eye level but do not materially detract from the gem appeal, and these inclusions can include minute crystal inclusions, tiny feathered planes, and growth related zoning that record the crystallization environment. Under modest magnification these features can be observed as fine signatures, akin to a fingerprint, and they are often used by gemological laboratories and experienced practitioners to confirm natural origin and to distinguish individual stones from one another. Because no enhancement has been made, the internal texture is natural and unchanged, offering confidence that the inclusions are original and stable, and that the gem has not undergone diffusion, filling, or heat treatments that might alter those identifying features.

In terms of practical considerations for use and care, the round mixed brilliant shape and the compact dimensions make this sapphire a versatile candidate for a range of settings, from solitaire rings to accent stones in multi stone compositions, where the light color intensity and parti nature can serve as a subtle design focal point. The excellent polish supports secure bezel or prong settings without concern for polishing related surface issues, and the stone hardness and toughness typical of corundum allow for normal wear provided routine care is observed, such as avoiding harsh chemicals and sharp impacts. The Natural Sapphire Company can provide detailed documentation of the item description, and we recommend that any decision be guided by the specifications provided, including carat weight 0.61, shape round, dimensions 5.29 by 5.28 by 3.05 mm, cut mixed brilliant, clarity very slightly included at eye level, color intensity light, polish excellent, enhancement none, origin Ceylon Sri Lanka, and faceted cutting style. This factual presentation is intended to assist in appraisal and design choices, and to support informed selection of this naturally formed, characterful sapphire.
