1.48 Ct. Bluish Green Sapphire from Madagascar

This 1.48 carat oval bluish green sapphire from Madagascar presents a precise combination of weight and proportions that will satisfy discerning gem buyers. The stone measures 7.90 by 6.16 by 4.11 millimeters, yielding a depth of approximately 58.5 percent relative to the average diameter, a range that balances strong light return with preserved faceup size. The cutter employed a mixed brilliant cut, combining a brilliant faceted crown with a carefully configured pavilion designed to concentrate return of light while maintaining color saturation, and the result is a gem that reads as transparent and lively across multiple viewing angles. Color grading places the stone at vivid intensity, a term indicating both high saturation and strong tone that produces rich bluish green appearance under standard viewing conditions. Clarity is described as very slightly included at eye level, meaning inclusions are minimal and do not interrupt the overall transparency or compromise durability, and the excellent polish and well executed facet junctions contribute to crisp facet reflections and maximum scintillation. The sapphire has been heat treated, a stable and industry accepted enhancement that optimizes color and reduces the visibility of minor inclusions, and provenance from Madagascar is consistent with the trace element profile that typically produces bluish green hues in corundum.

From a faceting and optical engineering perspective, this oval mixed brilliant is optimized to show pleochroic shifts between blue and green, a behavior characteristic of many natural sapphires, and the thoughtful pavilion cutting preserves these directional color variations rather than washing them out. The mixed brilliant crown provides numerous small star and kite facets that generate brilliant highlights, while the pavilion geometry returns broad flashes of color that emphasize the vivid saturation. The modest depth and the oval outline create an efficient faceup area, so the gem will appear larger than its weight might suggest when set with the long axis aligned with the finger. Given the very slightly included clarity grade and the excellent polish, standard prong settings will secure the stone without obscuring the crown facets, and a low to medium profile mounting with an open gallery will allow light to enter the pavilion and maximize the gem's dynamic range. For protection and design stability, a four or six prong setting can be specified, with a tapered prong treatment to reduce metal coverage of the table and preserve the visual aperture. The heat treatment is permanent under normal wear conditions, and ordinary maintenance practices for corundum apply.

For a custom design, thoughtful pairing of complementary gemstones and metals will highlight the bluish green character and the mixed brilliant faceting. A halo of small round brilliant white diamonds will create high contrast and increase perceived brightness, the white brilliances reflecting into the crown facets and making the center sapphire read with greater vibrancy, and a graduated pavé on the shoulders using melee diamonds will elongate the visual flow while preserving the mixed brilliant interaction. For a color graded ensemble, consider pairing the center with teal tourmalines or small party colored sapphires that echo the blue green axis, or use green tsavorite garnets for a lively, saturated green contrast that will push the center stone toward its bluer aspect. Metal choice will further tune the presentation, platinum or white gold reinforcing cooler blue notes and enhancing brilliance, while 18 karat yellow gold or rose gold will warm the overall look and coax forward the green component of the hue. A three stone configuration with tapered baguette diamonds set along the long axis will emphasize length and classical geometry, whereas a bezel with a fine milgrain edge will offer a contemporary, secure setting that showcases the clean pavilion while softening the profile for daily wear. At The Natural Sapphire Company we can provide CAD mockups and mounting recommendations to balance color interaction, facet visibility, and wearability, ensuring the final piece takes full advantage of the stone's vivid color, mixed brilliant faceting, and Madagascar origin.
