2.62 Ct. Greenish Blue Sapphire from Madagascar

This emerald cut greenish blue sapphire weighs 2.62 carat, and measures 8.12 x 6.92 x 4.41 mm, offering a balanced face up presence that reads larger than many stones of similar weight because of its well proportioned outline. It exhibits a dark color intensity, which for sapphires is often associated with richer saturation and visual depth, and it is transparent with a clarity grade of slightly included, evaluated at eye level. The pavilion and step facets have been given an excellent polish, producing crisp facet junctions and smooth planes that enhance the stone face up. This sapphire has been heat treated, a standard and accepted enhancement that improves color uniformity and can slightly reduce the visibility of inclusions, and it is from Madagascar, a source noted for producing sapphires with vivid and uncommon color ranges. At The Natural Sapphire Company we disclose treatments and origins because transparency is essential to value assessment and buyer confidence.

Color is the primary driver of value in sapphires, and this greenish blue tone is particularly appealing to connoisseurs who appreciate nuance and complexity. The greenish blue description indicates a notable contribution from iron chemistry in the corundum crystal, coupled with titanium influence that creates the familiar blue components, and the result is a cooler, more nuanced blue than the pure cornflower and a fresher, more oceanic alternative to classic midnight blue. A dark color intensity here means the hue is strongly saturated without becoming blackish, preserving both depth and legibility of color under a range of lighting conditions. Many buyers compare sapphires from Madagascar with those from Sri Lanka and from historic deposits such as Kashmir, and while Kashmir material is legendary and rare, Madagascar has emerged as a modern source of highly attractive sapphires with excellent color potential. Heat treatment is stable and permanent when performed on corundum, and it is widely accepted in the industry when properly disclosed, because it can bring out the best natural color in a gem without undermining its long term stability.

Clarity and cut determine how that color and light interact, and the emerald cut on this sapphire emphasizes broad, elegant flashes of color rather than the brilliant scintillation associated with brilliant cuts. The emerald cut is a step cut, so it produces broader planes that display the stone color uniformly, and it yields dramatic, mirror like flashes that allow the eye to appreciate color saturation and internal character. With a depth that equates to approximately fifty eight point six percent of the average of the length and width, this gem is well proportioned for an emerald cut, balancing face up size and light return. Sapphire has a refractive index roughly in the range one point seven six two to one point seven seven zero, and that high index, combined with the excellent polish, ensures strong light return and a distinct visual presence. Compared to more common gemstones used in blue jewelry, a diamond will typically show greater brilliance and dispersion due to its higher refractive index and cutting style, but diamonds do not offer the same range of saturated blue green color that makes a sapphire like this stand out. Compared to aquamarine and blue topaz, which are often lighter and less saturated, this sapphire has a richer hue, higher refractive index, and much greater hardness, with a Mohs hardness of nine, which makes it more suitable for everyday wear.

For an educated buyer this stone represents a compelling combination of attributes that matter in the secondary market and among collectors, namely color rarity, solid carat weight, stable enhancement, and a respected origin. The 2.62 carat weight in an emerald cut is not common, particularly in a greenish blue tone that remains transparent and evenly saturated across the table. The slightly included clarity means the gem is largely eye clean and the inclusions that are present are typical of natural corundum, often appearing as fine rutile silk or minute crystals that can actually enhance the gem character and prove natural origin under magnification. The excellent polish and the durable nature of corundum combine to make this stone practical for a fine ring or a pendant that will be enjoyed daily. From an investment perspective, Madagascar origin sapphires are increasingly sought after, and the disclosed heat treatment is standard trade practice that preserves marketability. At The Natural Sapphire Company we can advise on settings that showcase the step cut to its best advantage, such as a bezel that emphasizes the clean lines or a halo setting that contrasts the broad color flashes, and we stand behind our disclosures so that you can buy with confidence. If you seek a greenish blue sapphire that blends classic step cut elegance with the robustness and depth of natural corundum, this gem is an excellent choice.
