1.55 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This oval shape yellow sapphire weighs 1.55 carats and measures 7.14 x 5.73 x 4.38 millimeters, presenting a well balanced silhouette that reads as both elegant and substantial for an engagement center stone. The transparency is clean and bright, with the stone graded as slightly included at eye level, and the color graded as medium intensity, which gives a vivid yellow presence without overpowering warmth. The cut is a mixed brilliant style, executed to maximize light return while preserving weight and color, and the polish is graded excellent, with crisp facet junctions and a smooth table surface. This sapphire originates from Ceylon Sri Lanka, and it has been heat treated, a stable enhancement widely accepted in the trade that improves tone and saturation while leaving the crystal structure intact. At The Natural Sapphire Company we present this gem as a precise and responsibly sourced option for a customized engagement setting.

The mixed brilliant cut on this oval combines a brilliant style crown with a pavilion designed to balance fire and scintillation, producing an attractive play of light across the length of the stone. The cutter has optimized crown and pavilion angles to favor strong return of white light and lively scintillation, while maintaining controlled dispersion so that the yellow hue remains saturated and even. In practice this means the gem shows lively pinpoint flashes under direct light and a calm, even glow in softer illumination. The facet pattern is symmetrical, the table is well centered, and the overall faceting design preserves both brilliance and face up color, traits that are essential in a center stone intended for daily wear. The mixed brilliant approach is particularly effective in oval shapes because it marries the elongated elegance of the outline with the vitality of a brilliant facet scheme, creating a center stone that reads larger than its carat weight suggests.

Color and clarity are of particular importance in yellow sapphires, and this stone’s medium color intensity offers a desirable balance between saturation and lightness. The hue is a true yellow leaning slightly toward warm tones without perceptible green or brown modifiers, delivering a pure and wearable color that complements many skin tones. Medium intensity means the saturation is strong enough to be unmistakable, while the tone remains in a range that reflects light effectively, avoiding the muted appearance that can occur with very dark stones. The clarity is slightly included when viewed at eye level, and the inclusions are minor, not affecting durability or structural integrity. These inclusions serve as natural fingerprints, often useful in origin verification and in confirming that the sapphire is natural, not synthetic. The heat treatment applied is a standard, permanent process that enhances color uniformity, and it is disclosed openly, as transparency about enhancement is central to our ethical practice. With a hardness of 9 on the Mohs scale and excellent polish, this sapphire is well suited to daily wear in a ring setting, providing long term performance with proper care.

For an engagement ring this oval sapphire offers several practical and aesthetic advantages. The length to width ratio is approximately 1.25, a proportion that favors an elegant oval profile which elongates the finger while maintaining a broad and communicative face up area. In a solitaire setting the gem will present a timeless, focused silhouette, while a halo of small brilliant cut diamonds will amplify perceived size and add contrast that enhances the yellow saturation. Yellow and rose gold settings warm the stone further, reinforcing its sunny character, while white gold or platinum create a modern, high contrast look that emphasizes brilliance and facet detail. Prong settings allow maximum light exposure and accentuate the mixed brilliant cut, whereas a thin bezel can be used for a more secure, low profile option without losing the oval elegance. For buyers who prioritize longevity, we recommend a setting with secure, well placed prongs and a protective gallery designed to mitigate side impact. At The Natural Sapphire Company we can assist with design choices that match lifestyle and aesthetic preferences, providing detailed CAD visuals and setting options, and delivering a finished engagement piece that highlights the sapphire’s provenance, technical excellence, and visual appeal.
