3.14 Ct. Greenish Blue Sapphire from Madagascar

This 3.14 carat oval greenish blue sapphire is a finely proportioned example of natural corundum, with dimensions of 10.07 by 7.27 by 5.18 millimeters, originating from Madagascar. The gem exhibits a medium color intensity with a distinct greenish blue hue that will appeal to connoisseurs who value nuance in saturation and tone. Clarity has been assessed as very slightly included, evaluated at eye level, meaning that the stone retains excellent transparency and face up performance while presenting only minor natural inclusions that do not detract from its overall visual impact. This sapphire has undergone standard heat treatment, a stable and widely accepted enhancement that has optimized the stone s color and clarity without compromising its structural integrity. Presented by The Natural Sapphire Company, this specimen represents the sort of material that complements a high end gemstone collection, combining attractive weight, appealing color, and verifiable origin.

The cutting and polishing reflect deliberate technical choices intended to balance weight retention with optical performance. The mixed brilliant cut integrates a modified brilliant crown with a pavilion that emphasizes controlled light return, providing a lively mix of brilliance and scintillation while preserving depth of color. With a length to width ratio of approximately 1.39, the oval silhouette reads as elegantly elongated without appearing too narrow, a proportion favored for both display and wearable settings. The measured depth of 5.18 millimeters yields an approximate depth of 59.8 percent relative to the average diameter, a proportion that falls within the ideal range for oval mixed cuts and supports efficient light travel through the pavilion. Facet geometry shows careful attention to junction sharpness and meeting angles, producing crisp facet boundaries and an excellent polish that translates into mirror like facet surfaces and clean light refraction. The cutter s intention is evident in the balance between crown and pavilion facet sizes, which has been calibrated to enhance both the stone s color saturation and its dynamic optical response, including the slight pleochroic shift characteristic of corundum that allows subtle shifts toward more blue or more green depending on viewing orientation and light source.

From a gemological and curatorial perspective, this sapphire offers traits collectors specifically seek. Madagascar origin contributes to the gem s profile, as material from this locality often shows attractive, medium saturated hues and a suite of internal features consistent with natural corundum formation, such as fine rutile silk and microscopic mineral inclusions, without the intrusive indicators associated with lower quality stones. The heat treatment applied is conventional, conducted to stabilize and enhance the greenish blue balance, and it is permanent under normal wear conditions, making the stone suitable for secure jewellery mounting. Craftsmanship details include a well defined girdle and an expertly executed pavilion that minimizes light leakage while maintaining carat weight, and the excellent polish ensures long term luster and resistance to surface abrasion during setting. For collectors considering presentation or incorporation into high end jewellery, this sapphire adapts well to a solitaire pendant, a classic four or six prong ring with an open pavilion to maximize light entry, or a bespoke three stone or halo composition where its medium intensity and refined proportions will be complemented by carefully chosen accent stones. The Natural Sapphire Company can provide detailed imagery, viewing under both daylight corrected and incandescent sources, and independent assessment documentation upon request, making this 3.14 carat greenish blue oval a technically sophisticated addition to a discerning collection.
