1.21 Ct. Greenish Blue Sapphire from Madagascar

This sapphire is a transparent, greenish blue oval weighing 1.21 carats, with dimensions of 7.10 x 5.03 x 3.90 mm, and originates from Madagascar. The stone has a mixed brilliant cut and an excellent polish, characteristics that contribute to a clean, lively face up appearance. Color intensity is described as dark, presenting a concentrated and saturated field of color that reads as deep greenish blue in standard lighting. Clarity is graded as very slightly included at eye level, indicating that inclusions are minor and do not detract from the gem when viewed in typical jewelry use. This sapphire is unenhanced, remaining in its natural state, a detail we document carefully at The Natural Sapphire Company.

The greenish blue hue of this sapphire is its defining visual attribute, and the combination of saturation and mixed brilliant cutting makes that color particularly assertive in jewelry. In settings that allow the stone to receive light from multiple directions, the mixed brilliant cut returns scintillation and dynamic facet interplay, producing flashes that shift between more vibrant blue and cooler green tones. The dark color intensity gives the gem a jewel like depth that reads as sophisticated and substantial, especially when contrasted with bright metalwork or accent stones. Because the sapphire is transparent, light penetrates into the pavilion and is refracted by the cutting geometry, which intensifies face up color and contributes to a visual presence that stands out even when the stone is modest in carat weight.

Beyond its color, the physical and optical properties of this sapphire support design flexibility and long term wearability. Corundum, the mineral family to which sapphire belongs, rates 9 on the Mohs hardness scale, and paired with an excellent polish and tight cutting, this stone is well suited to daily wear in rings, necklaces, and bracelets. The oval outline and the specific dimensions provide a balanced length to width ratio that complements prong, bezel, and low profile settings. The very slightly included clarity grade means that the stone offers clean fields to the eye, while inclusions are primarily internal and do not compromise structural integrity. The mixed brilliant cut increases the apparent brilliance for the carat weight, helping the gem read larger face up and making the greenish blue color more perceptible in ambient light.

When considering design context, the sapphire’s dark, greenish blue character will create distinct aesthetic relationships with different metals and side stones. Set in platinum or white gold, the deep hue will appear crisp and cool, with the metal accentuating blue notes and lending a contemporary contrast. Set in yellow gold, the same color will gain a warmer, more classical appearance, as the surrounding metal highlights green undertones and produces a striking dialogue between hue and metal warmth. A halo of small diamonds will increase the perceived size and brightness of the center stone, providing sparkling contrast that emphasizes the sapphire’s saturated color. For protective purposes, a bezel setting will shelter the girdle and edges while preserving the gem’s visual depth, whereas a four or six prong design will maximize light entry and accentuate facet dance, ensuring the greenish blue tone remains vivid from multiple viewing angles.

This natural, unheated Madagascar sapphire exemplifies attributes that are important to both gem professionals and clients seeking an authentic color experience. The combination of 1.21 carat weight, mixed brilliant cut, excellent polish, very slightly included clarity, and natural origin creates a balance between visual impact and practical use. Documentation of unenhanced status and origin supports transparent acquisition, and the stone’s optical behavior ensures it will be a focal point in a wide range of settings. At The Natural Sapphire Company, we present this gem as an option for commissions that require a bold yet refined color statement, and as an adaptable center that will stand out in any jewelry setting, maintaining its presence through design choices that celebrate its greenish blue vibrancy.
