1.10 Ct. Greenish Blue Sapphire from Madagascar

This 1.10 carat oval greenish blue sapphire from Madagascar represents an exceptional opportunity to add a refined and rare natural corundum to a high end collection. The gem measures 6.87 by 4.88 by 3.75 millimeters, yielding a depth percentage of approximately 63.7 percent, which sits well within the ideal range for ovals and supports a pleasing face up appearance that balances spread and depth. Cut as a mixed brilliant, the pavilion and crown design has been executed to maximize light return while preserving weight, an important consideration for collectors who value both visual performance and efficient carat distribution. The stone is transparent, with intense color saturation and excellent polish, attributes that contribute directly to its presence when set in fine jewelry or displayed as a collector specimen. As with all items sourced through The Natural Sapphire Company, this sapphire is presented with full transparency regarding its origin and enhancements, and in this case the gem is natural with no enhancement, which significantly elevates its desirability among educated buyers.

Color is the defining characteristic of this sapphire, presenting a sophisticated greenish blue hue that shifts slightly depending on light and orientation, a behavior that is consistent with the pleochroic nature of corundum. The intensity of the color is described as intense, meaning the gem shows strong, saturated tones across the face up view without appearing overly dark. Madagascar has become well regarded for producing sapphires with a broad and nuanced range of blue to green blue tones, and this stone exemplifies that regional character with a cool, slightly teal-inflected palette that reads as modern and versatile. For a collector, this specific color profile is valuable because it is distinct from the pure velvety blues of classic Sri Lankan material and the velour-like saturation seen in some Kashmir stones. The presence of strong color saturation combined with transparency allows the sapphire to display lively scintillation and internal color zoning that can be attractive under both natural and artificial light, enhancing its appeal as a display gem or a center stone in high end jewelry.

From a clarity and cutting perspective, the sapphire is graded as slightly included when evaluated at eye level, which means that minor inclusions are present but do not significantly interfere with the overall brilliance or the perception of color. Slightly included eye level clarity is often acceptable and even preferred by collectors who appreciate natural character in gemstones, since internal features can provide evidence of natural origin and are one of the indicators a gem has not been extensively treated to improve appearance. The mixed brilliant cut enhances brightness through many small facets on the crown, while the pavilion facets are oriented to complement the stone’s pleochroism and depth, producing pleasing return of light and flashes of blue and green. The excellent polish ensures that facet junctions are clean and reflective, which amplifies sparkle and gives the gem a crisp, fresh face up presentation. Together, these factors make the sapphire particularly suited to settings that favor visibility of color and light, such as open prong or halo designs that allow unobstructed viewing of the pavilion and girdle.

For an educated buyer building or refining a high end gemstone collection, this Madagascar greenish blue sapphire offers a compelling combination of provenance, rarity, and natural character. The fact that the stone has no enhancement is a notable advantage in the current market, where untreated material carries a premium among discerning collectors and investors, because it reflects original formation conditions rather than laboratory alteration. The measured proportions, mixed brilliant cutting, intense color, and excellent polish all contribute to a gem that balances aesthetic appeal with sound gemological fundamentals, making it versatile for both museum quality mounts and elegant daily wear pieces. As representatives of The Natural Sapphire Company, we emphasize provenance, ethical sourcing, and technical accuracy, and we can assist with independent gemological reporting, recommended settings, and long term care advice. Recommended settings that best showcase the cool, greenish blue tones include platinum or 18 karat white gold to emphasize the stone’s brilliance, or yellow gold to create a dramatic contrast that warms the overall appearance. Whether you are acquiring this sapphire for its collector value, for a bespoke jewelry commission, or as part of a curated investment portfolio, its combination of untreated origin, pleasing proportions, and refined cutting make it a distinguished and enduring addition to a high end collection.
