0.37 Ct. Bluish Green Sapphire from Madagascar

This transparent bluish green sapphire, weighing 0.37 carat, is a refined and elegant specimen that belongs at the center of any serious gemstone collection. Precisely measured at 3.87 by 3.92 by 3.14 millimeters, it is cut into a round shape with a mixed brilliant cut that balances scintillation and depth, offering both lively fire and a pleasing table face for close inspection. The clarity is described as very very slightly included when evaluated at eye level, meaning the stone reads as eye clean to most observers while retaining natural character under magnification. The color intensity is light, which lends this sapphire a delicate, sophisticated presence that reads as bluish green rather than a saturated primary hue, and the excellent polish ensures clean, bright facet intersections and maximum light return. Originating from Madagascar, and enhanced by heat treatment, this sapphire combines natural beauty with professional finishing to present a stone that is transparent, stable, and ready to be set into a piece that highlights its unique color dynamics.

Compared to other sapphires currently available on the market, this Madagascar bluish green offers a distinctive compromise between rarity and value. Pure blue sapphires, while widely coveted, are more commonly encountered and command premiums for deep saturation and origin appeal. Rich green sapphires present a different market and often lean toward darker tones. This bluish green hue occupies an elegant middle ground that is rare in consistent quality at this size, offering collectors a unique hue that stands apart from the usual offerings. The mixed brilliant cut elevates the gem beyond typical step or standard cuts, producing a nuanced interplay of brightness and contrast that many round sapphires in this weight range lack. The very very slightly included clarity grade is superior to the more common slightly included examples in this size bracket, meaning that under standard viewing conditions the gem displays a clear, open window into its color and structure, an advantage for collectors who prefer stones that photograph and display well under jewelry settings. Heat treatment is a well established and accepted enhancement in the trade, applied to stabilize and refine color, and it allows this stone to present a clean tone without compromising durability. From a value perspective, this sapphire from Madagascar offers a superior per carat proposition when compared to stones of similar appearance from overrepresented sources, because it combines desirable color harmony, excellent polish, and an above average clarity profile at a modest carat weight.

For the high end collector who curates pieces for aesthetic diversity, investment potential, and wearable versatility, this sapphire is an ideal addition. Its light bluish green tone makes it exceptionally adaptable, suitable for use as a refined accent stone in bespoke engagement settings, a subtle center for a delicate pendant, or as part of a coordinated suite where contrasting colors are required. Because of its transparent nature and excellent polish, the gem will respond well to mixed metal mountings, enhancing both warm and cool palettes without losing its unique identity. Collectors who prioritize provenance and reputable sourcing will appreciate that this gem is offered through The Natural Sapphire Company, a name associated with careful selection and transparent documentation. The Madagascar origin gives the sapphire a contemporary provenance story, reflecting the emergence of new, high quality deposits that produce tones not always available from more established localities. Compared to stones that require extensive cutting to remove obvious inclusions or to reach acceptable color, this example demands minimal alteration, preserving weight and maximizing the intrinsic value of the crystal.

Selecting a single stone for a high end collection is as much about character and story as it is about gemological parameters, and this 0.37 carat round bluish green sapphire excels on both counts. It presents an uncommon color profile at an approachable size, it is cut to optimize optical performance with a mixed brilliant layout, and it carries a clarity that allows collectors to enjoy an open, lively appearance without resorting to heavy enhancement. When placed alongside more traditional deep blue or vivid green sapphires, this gem introduces a subtle, modern note that elevates a collection by offering contrast, balance, and refined taste. For those seeking a stone that blends natural origin, technical quality, and collectible value, The Natural Sapphire Company presents this Madagascar sapphire as a thoughtful acquisition, ready to be set, studied, and cherished as part of a discerning high end collection.
