1.51 Ct. Bluish Green Sapphire from Madagascar

Owning a truly distinctive gemstone is a declaration of refined taste and rare opportunity, and this bluish green sapphire offered by The Natural Sapphire Company answers that call with quiet authority. At 1.51 carats this transparent emerald cut sapphire occupies a special place between dainty and distinctly presence driven, a weight that elevates it beyond a mere accent stone to a centerpiece for a refined ring pendant or bespoke commission. The gem measures 7.03 by 6.20 by 3.46 millimeters, dimensions that combine an elegant table and well balanced depth, allowing the medium intense bluish green personality of the crystal to sing with clarity and controlled fire. Graded as very slightly included when evaluated at eye level, the sapphire reveals natural character without compromising brilliance, and its excellent polish yields crisp facet reflections that enhance the cut geometry. Heat treated to stabilize and optimize color, and originating from the storied alluvial deposits of Madagascar, this stone is a rare expression of nature and human skill, made available in extremely limited quantity through The Natural Sapphire Company.

The weight of 1.51 carats is central to the sapphires value and rarity in ways that extend beyond simple metrics. In the world of colored gemstones, every fraction of a carat shifts scarcity, pricing, and visual impact, and crossing the one and a half carat threshold opens a new class of desirability. This particular size is large enough to command attention on the hand while retaining the versatility to be set in many elegant styles, from a refined solitaire to an artful halo or modern bezel, each setting giving the gem a different facet for admiration. The emerald cut shape accentuates the stone weight by producing a broad, open table and long clean facets, which translate the 1.51 carats into a graceful face up size that looks generous without overwhelming. The proportions of 7.03 by 6.20 millimeters allow the stone to sit with balanced presence on a finger, making the weight feel both luxurious and wearable. For connoisseurs who appreciate the algebra of light and mass in a gemstone, this sapphire demonstrates how weight and cut collaborate to create a rare harmony, a quality that only a few stones in any season can offer.

The character of this Madagascan sapphire is defined by its medium intense bluish green color, a hue that reads as sophisticated and quietly exotic, and by its clarity described as very slightly included at eye level. These very minor natural inclusions serve as a fingerprint of origin and authenticity, confirming that the gem is a natural corundum rather than a synthetic or heavily enhanced substitute, while remaining subtle enough to preserve impressive transparency. The heat treatment disclosed with the stone is a standard, accepted enhancement in the industry, applied with restraint to stabilize color and reveal the gemspath inherent charm, never to compromise structural integrity. The excellent polish is not a trivial detail, it refines how light travels through the pavilion and across the emerald cut facets, sharpening facet junctions and maximizing the steady, refined luster that collectors prize. Madagascar as a source contributes its own narrative, an island known for producing sapphires with nuanced color zones and velvety overtones that can shift with viewing angle, a living quality that invites a private relationship between wearer and gem.
