1.34 Ct. Bi Color / Parti Sapphire from Montana

One beautiful transparent 1.34 carat oval bicolor parti sapphire presents an exceptional combination of size, shape, and optical interest, it measures 6.17 by 5.55 by 4.39 millimeters, the cutting style is faceted with a mixed brilliant cut, the polish is excellent, and the overall face up appeal is notable for a stone of this weight and profile. The color has medium intensity, offering a pleasing balance between saturation and versatility, and the bicolor or parti character can display complementary tones as the stone is rotated in light, adding dynamic interest for design applications. Clarity is graded as very very slightly included when evaluated at eye level, meaning that inclusions are minimal and do not detract from the gem when worn, the inclusions are typically only evident under magnification or careful scrutiny, and they serve as natural signatures that confirm the gem is a natural sapphire rather than synthetic. The piece has been heat treated, a widely accepted and permanent enhancement in sapphire trade practices that stabilizes and improves color and clarity while preserving the structural integrity of the corundum, and the origin of this sapphire is Montana, a region known for producing parti and pastel sapphires with subtle, earthy to pastel hues that appeal to collectors and designers seeking a natural aesthetic.

For custom jewelry this oval bicolor parti sapphire is particularly advantageous, the oval outline maximizes perceived table size relative to weight, making a 1.34 carat oval read larger on the finger or pendant than many round stones of similar carat weight, and the dimensions 6.17 by 5.55 by 4.39 millimeters place this gem squarely in the ideal range for engagement rings, three stone rings, pendants, and statement earrings. The mixed brilliant cut promotes strong light performance while the faceting pattern enhances the play between the two color zones typical of parti sapphires, which means that careful orientation in the setting will allow a designer to emphasize either the warmer or cooler tones depending on the intended aesthetic. From a setting perspective a four or six prong head will display maximum table and brilliance, a halo will magnify the perceived size and add contrast to the parti coloration, a bezel setting will protect the girdle and crown for an active wearer and can create a modern, clean look that pairs well with the natural color shifts, and an east west orientation can lend a contemporary feel while also showcasing the length of the oval shape. The depth of 4.39 millimeters also provides adequate pavilion depth for secure bezel or prong seats without excessive re cutting, and a skilled jeweler can plan seat depths and prong placement to avoid color leakage or unwanted windows while optimizing the visible color zones.

To an educated buyer this sapphire represents an appealing balance of quality, character, and practicality, Montana sapphires are prized for their distinctive color range and rarity relative to more common sources, the very very slightly included clarity grade indicates a clean gem that maintains natural identity and stability, and the excellent polish and mixed brilliant faceting ensure efficient light return and a lively appearance on the hand. Heat treatment is fully disclosed, it is the standard industry enhancement for sapphires and is considered stable and permanent, it does not diminish the gemological value when properly represented, and it allows the inherent beauty of the crystal to be realized for jewelry use. For custom work The Natural Sapphire Company recommends discussing orientation of the stone early in the design phase so that the parti colors can be positioned to best effect, and consideration of metal color and accent stones will further influence how the two tones are perceived, yellow or rose gold can warm the warmer zones and white metals can enhance contrast and brightness in the cooler zones. This sapphire is durable for everyday wear due to the inherent hardness and toughness of corundum, and it offers a collectible quality for buyers who appreciate provenance, natural inclusions as identifying characteristics, and the creative possibilities of a bicolor gem, please contact The Natural Sapphire Company for detailed mounting recommendations, custom design options, and secure appraisal documentation to ensure the finished piece meets your technical and aesthetic expectations.
