1.71 Ct. Orangish Brown Sapphire from Ceylon (Sri Lanka)

This GIA certified, transparent, Brownish Orange sapphire presents as a round, orangish brown gem of 1.71 carats, with exact dimensions of 6.59 by 6.59 by 5.23 millimeters, a mixed brilliant cut, an evaluated clarity of very slightly included at eye level, intense color intensity, excellent polish, no enhancement, and an origin of Ceylon Sri Lanka. The GIA certification confirms the gemology, weight, and the absence of treatment, a combination that places this sapphire in a rare category for engagement use. The round shape provides a classic silhouette that is immediately familiar on the hand, while the mixed brilliant design preserves a balance between scintillation and color saturation. The untampered, natural color from Ceylon delivers a warm, complex palette that reads as brownish orange in direct lighting, and as a deeper orangish brown in more diffuse environments.

From a cut perspective, the mixed brilliant configuration is specifically chosen to optimize light performance for corundum of this hue and depth. The crown is faceted in a brilliant pattern to maximize top light return, while the pavilion employs modified facets that channel light back through the crown to create lively scintillation without washing out the sapphire s chroma. The pavilion depth relative to diameter produces a depth ratio of approximately 79.3 percent, a proportion that increases internal light paths and therefore enhances face up saturation in a colored stone. This deeper pavilion contributes to the intense color intensity recorded on the report, and it also reduces the risk of windowing that can occur when a stone is cut too shallow. The excellent polish ensures that facet junctions are crisp, minimizing micro surface diffusion and allowing specular reflection to reach the eye, while the careful symmetry of facet placement maintains even light return across the table.

Clarity characteristics are consistent with a high quality Ceylon sapphire, and are described as very slightly included when evaluated at eye level, a practical and market relevant observation. These inclusions are minor in scale and distribution, and in stones of this color they frequently manifest as pinpoint crystals or fine silk that can act to slightly soften the appearance and add a velvety, saturated look rather than detract from brilliance. Because the cutting strategy emphasizes a modest table and a deeper pavilion, the cut hides inclusions in less conspicuous locations, preserving a clean face up presentation while maintaining structural integrity. The absence of enhancement is significant from both valuation and permanence viewpoints, offering stability under routine jewelry wear, and allowing for a natural interaction between inclusions, color, and light that many connoisseurs prefer.

As an engagement gemstone, this 1.71 carat Ceylon sapphire is an exceptional choice on technical and aesthetic grounds. The corundum species rates a nine on the Mohs hardness scale, providing superior resistance to abrasion and everyday wear, and the round mixed brilliant cut is time tested for engagement applications where both durability and optical performance matter. The warm brownish orange tone of this piece pairs particularly well with yellow and rose gold, where the metal complements the stone s inherent warmth, and with platinum or white gold where contrast will create a striking, modern presentation. Settings that expose the pavilion and allow side light, such as four or six prong designs, maximize the dynamic interplay of brilliance and color, while bezel or low bezel settings can be selected when impact protection is a priority. The Natural Sapphire Company stands behind the GIA certification and the untampered origin, and we can advise on mounting choices to preserve the sapphire s optical properties and long term value. For buyers seeking an engagement gem that combines verified provenance, meticulous cutting, and an arresting warm hue, this Ceylon round mixed brilliant sapphire represents a rare, technically superb option.
