1.06 Ct. Bluish Green Sapphire from Ceylon (Sri Lanka)

This one point zero six carat round bluish green sapphire is a study in measured craftsmanship and natural material quality. The stone measures five point seventy six by five point seventy eight by three point ninety millimeters, and presents as transparent with an intense color intensity. Cut as a mixed brilliant, the design pairs a faceted brilliant style crown with a precision stepped pavilion arrangement, producing both strong scintillation and controlled color return. Clarity is graded as very slightly included at eye level, and the very slight inclusions do not interrupt the gem s overall transparency. The finish is an excellent polish, and the stone has been heat treated, a stable enhancement that is standard for sapphires and documented in our disclosure. Origin is Ceylon Sri Lanka, a provenance known for stones that balance saturated color with lively tone variation. The Natural Sapphire Company presents this sapphire as an example of technical cutting allied with desirable natural material properties.

The mixed brilliant cut on this piece is engineered to optimize both light performance and color depth, with a crown faceting scheme that disperses light while maintaining an open table, and a pavilion configuration that concentrates and returns color to the observer. With an average diameter of approximately five point seven seven millimeters and a depth of three point nine zero millimeters, the depth to diameter ratio is approximately sixty eight percent, a proportion that favors vivid color saturation without sacrificing face up spread. The crown facets are calibrated to produce crisp flashes of white light, while the pavilion facets are cut to create measured internal reflection pathways that reinforce the bluish green hue. Facet junctions are clean and symmetrical, and the girdle presents a consistent profile that facilitates secure setting. The mixed cutting strategy is particularly effective for Ceylon material, as it allows the cutter to harness both pleochroic color shifts and the material s refractive properties in order to create dynamic visual interest from multiple viewing angles.

Color evaluation for this sapphire emphasizes intensity and balance rather than a single flat tone. The dominant visual impression is a bluish green, with blue leaning saturation enhanced by green modifiers that emerge under certain viewing geometries. The stone exhibits pleochroic tendencies consistent with corundum, so color presentation varies gently as the stone is rotated or as light source and angle change. This variability is a desirable trait for informed buyers, because it means the gem communicates color in motion rather than presenting as static. The intense color intensity reported is the result of both the natural trace element content typical of Ceylon corundum and the controlled heat treatment that optimizes color without over saturating the material. Because the sapphire is transparent and the polish is excellent, light penetrates and interacts with internal structure, producing both depth of color and lively brilliance. The result is a stone that rewards detailed inspection and reveals subtleties from every angle.

Clarity analysis notes that the stone is very slightly included when evaluated at eye level, which in practical terms means that any internal features are minor and do not detract from overall appearance in ordinary wear. Inclusions are small, positioned in such a way that they reduce neither the stone s transparency nor the efficiency of its faceting plan. From a technical perspective, the clarity grade complements the mixed brilliant design, because the cutting strategy masks and minimizes the visual impact of internal characteristics while enhancing the stone s optical performance. The excellent polish is evident in the sharp facet edges and in the mirror like reflections off the table and crown facets. Polish quality contributes directly to perceived brilliance and to the stone s ability to reflect highlights, which is particularly important for a deep colored piece. For setting, recommendations include a bezel or secure prong construction that protects the girdle and pavilion and allows the crown to present unobstructed, thereby maximizing the optical benefits imparted by the cutter s proportions.

Taken as a whole, this one point zero six carat Ceylon bluish green sapphire is a technical success and an aesthetic asset, a stone whose careful cutting, documented treatment, and material provenance combine to enhance beauty from every angle. The mixed brilliant faceting delivers an interplay of scintillation and color concentration that is particularly effective on material with pleochroic character, while the very slightly included clarity and excellent polish ensure the gem reads as transparent and lively in practical use. The Natural Sapphire Company stands behind the descriptive grading and the disclosure of heat treatment, and recommends professional setting and routine gentle cleaning to preserve the stone s finish. For the knowledgeable buyer seeking a compact, intensely colored round sapphire with precise cutting and reliable origin documentation, this gem represents an exemplary option that will perform technically and visually for years to come.
