2.61 Ct. Bluish Green Sapphire from Madagascar

This transparent bluish green sapphire weighs 2.61 carats, a weight that immediately elevates its rarity and market value, and the size is further articulated by precise dimensions 9.31 by 6.79 by 5.34 millimeters. At this weight and size the gemstone occupies a premium position among natural corundum specimens, because sapphires of this clarity and color at and above the two and a half carat threshold are substantially less common than smaller counterparts. The length to width ratio of 9.31 divided by 6.79 is approximately 1.37, a proportion that reads as a classic oval, offering a strong face up presence without appearing squat or overly elongated. Depth relative to the mean diameter is approximately 66 percent, a proportion that balances strong light return with optimal table size, enhancing both perceived size and scintillation. The Natural Sapphire Company presents this stone as entirely unenhanced, a condition that meaningfully increases both immediate retail value and long term investment appeal, because untreated corundum commands a clear premium in markets that value natural state and provenance.

The cutting is faceted in a mixed brilliant style, a deliberate choice to reconcile color distribution with maximum brilliance and scintillation. Mixed brilliant cutting integrates brilliant style facets on the crown with modified or step influenced pavilion facets, and in this oval the result is a lively interplay between pinpoint sparkle and broader flashes of light, while preserving depth of color across the table. The excellent polish elevates the facet junctions to crisp meeting points, minimizing surface diffusion and allowing clean light refraction that emphasizes the stone clarity and body tone. Clarity is graded very slightly included evaluated at eye level, which in practice means small inclusions are restrained in number and scale and do not interfere with transparency or with the stone ability to return light, even in face up orientation. That clarity grade enhances the gem rarity at this weight, because the combination of transparency, minimal inclusions, and substantial carat weight is statistically uncommon in natural sapphires.

Color is described as bluish green with faint intensity, an appearance that in a mixed brilliant oval yields subtle, sophisticated coloration that can shift slightly with viewing angle due to pleochroism inherent to corundum. Faint color intensity in a transparent stone allows for a lively brilliance and a lighter face up appearance, while the bluish green hue provides an uncommon and attractive alternative to pure blue or pure green, appealing to connoisseurs who prize nuance and rarity in hue. Origin is Madagascar, a provenant source known for producing a broad palette of sapphire colors and for material with clean body color and good crystalline structure. From a mineralogical perspective the corundum refractive index near 1.76 to 1.77 and specific gravity near 4.00 contribute to strong brilliance and a satisfying heft in hand for a 2.61 carat stone. The fact that this sapphire is natural and not subjected to heat or other enhancements preserves trace element signatures and original crystal features, making it more desirable to collectors and to clients who prioritize untreated gemstones for ethical and investment reasons.

From a craftsmanship and setting perspective the 2.61 carat weight combined with oval proportions opens a range of design options that respect the gemstone technical characteristics. In a solitaire mounting the table and crown geometry will read large and bright, whereas a halo or step framed design will accentuate the hue and offer additional optical contrast that can make the faint bluish green appear richer. The mixed brilliant cut also means the stone will exhibit both scintillation and broad light fields, so prong patterns and bezel engineering should be chosen to preserve crown light entry and to avoid excessive obstruction of the pavilion. At The Natural Sapphire Company we calibrate setting recommendations to the stone depth and facet architecture to maximize face up performance while protecting the girdle and pavilion. For buyers who evaluate investment metrics the combination of 2.61 carats, natural untreated origin Madagascar, very slightly included clarity, excellent polish, and a skilled mixed brilliant cut presents a compelling value proposition, because each of these attributes compounds overall rarity and market desirability, creating a sapphire that performs both as a wearable jewel and as a collectible natural mineral asset.
