0.31 Ct. Greenish Blue Sapphire from Madagascar

This is a beautifully transparent 0.31 carat round sapphire from Madagascar, measuring 3.90 by 3.76 by 2.63 millimeters, cut in a mixed brilliant style and given an excellent polish. The gem shows a greenish blue hue with medium color intensity, a tone that sits intriguingly between the classic Ceylon blue and the cooler Australian teals, offering a distinctive look that is both versatile and quietly sophisticated. At this size the stone is ideal for delicate engagement settings, halo styles, or as a refined accent in a bespoke piece, and the mixed brilliant cut maximizes scintillation and face up brightness in ways that many standard round cuts do not. The sapphire has been heat treated, a stable and widely accepted enhancement that deepens and refines the stone’s color without compromising durability, and overall it presents a balance of natural charm and commercial practicality that is exceptional for the size and origin.

One of the most important assurances of a natural sapphire is the presence of inclusions, and this gem’s clarity grade of very slightly included evaluated at eye level tells you exactly what to expect. Under loupe or microscopic examination you will find minute inclusions that act like a fingerprint, small crystals and growth features that are unique to this individual stone and impossible to replicate in synthetic material. Rather than detracting from beauty, these internal characteristics confirm authenticity and add personality, they catch light in ways that can increase interest and depth when the stone moves, and they form a map of the gem’s geological history. Many collectors and connoisseurs prize such markers because they tell a story about formation and locality, and because they make each sapphire a one of a kind object, unlike lab created stones which are consistent and often overly flawless. The very slightly included grade evaluated at eye level also means the stone appears clean to most viewers at normal viewing distances, preserving elegance while retaining the natural identifiers that increase long term collectibility and provenance.

When evaluating this Madagascar sapphire against other market options, it stands out for a number of reasons. Compared with untreated stones from some famed localities, the heat treatment here is modest and stable, applied to bring out the gem’s medium intensity greenish blue without erasing its individuality, while many untreated stones with comparable color can be far more costly and rarer, making this piece a smart value play. Against lab grown sapphires, this gem offers natural origin, authentic inclusions, and a provenance of Madagascar that gives it character and desirability that cannot be duplicated by synthetic processes. Versus many commercial parcel goods that use generic cuts and average polish, the mixed brilliant cut and excellent polish give superior light performance and a refined face up appearance, so you get brightness and scintillation typically reserved for larger or higher priced stones. At The Natural Sapphire Company we emphasize the combination of natural identity, responsible enhancement, and skilled cutting, and this 0.31 carat, greenish blue, round mixed brilliant sapphire embodies those priorities, delivering a small but compelling stone that reads as elegant in hand, honest in origin, and strong in value compared with alternatives on the market. If you are considering a delicate solitaire, a custom stackable band, or a matching pair for pierced jewelry, this Madagascar sapphire offers a rare balance of color personality, natural inclusions, and craftsmanship that appeals to both the eye and the collector’s sensibility.
