Solitaire Bi Color Sapphire Ring 0.37 Ct., 14K White Gold

Long before the ring took shape in the workshop, this sapphire began its life deep within the storied gem gravels of Ceylon in Sri Lanka, a place that has produced remarkable sapphires for centuries. Nature conspired over millions of years to fold heat and trace elements into a transparent, bi color stone that displays a graceful dialogue between two hues. The rough was recovered with care, then examined by our gem specialists at The Natural Sapphire Company to confirm that this remarkable piece required no enhancement, so the color you see is entirely natural. What remained for us was to honor that origin, to respect the stone s inherent personality, and to reveal its inner fire through precise cutting and thoughtful mounting. The result is a 0.37 carat oval sapphire, with dimensions of 4.89 by 3.92 by 2.50 millimeters, medium color saturation, a clarity grade described as very slightly included when evaluated at eye level, and an excellent polish that lets light travel cleanly through the stone.

The cutter chose a mixed brilliant cut for this oval sapphire, a decision that balances color and sparkle in a way that feels both traditional and modern. Mixed brilliant cutting places brilliant style facets on the crown and combines them with a modified pavilion geometry, tailored to the elongated oval outline. That arrangement allows the sapphire to show lively scintillation when it moves, while maintaining strong color presence across the table, an important consideration for a bi color stone. At these compact dimensions the cutter worked to minimize the common oval bow tie effect, keeping the contrast pattern gentle and consistent so that the two color zones blend and shift rather than clash when the ring tilts. The excellent polish further contributes to crisp facet junctions and lively light return, creating a gem that reads more substantial than its 0.37 carat weight might suggest under flattering light.

Comparing light performance to other cuts and styles helps explain why this mixed brilliant oval behaves as it does. A classic round brilliant emphasizes maximum fire and scintillation, owing to a perfectly symmetrical facet pattern, but that shape would hide the bi color character. Step cuts such as emerald cut or baguette emphasize color and clarity, creating broad flashes of color but producing far less sparkle. When a sapphire is step cut, its depth of hue becomes the primary spectacle, which is wonderful for richly saturated stones, but a bi color gem benefits from some faceted complexity to show both tones dynamically. Cushion and radiant cuts offer more rounded brilliance and can emphasize warmth, but they often distribute color differently than an oval, sometimes concentrating color in corners. The mixed brilliant oval here gives you a lively interplay between sparkle and color, so the stone flashes as you move, and the bi color nature reveals itself in soft transitions rather than abrupt zones.

Set in a simple, elegant 14K white gold ring, the sapphire sits in a low profile solitaire setting that was designed to maximize the stone s ability to capture and return light. The minimal four prong setting exposes the girdle and pavilion to ambient light, which enhances the gem s brightness and lets the mixed brilliant facet pattern do its work. Compared to heavier or closed bezel settings, this open mount keeps reflections pure and natural, and the white gold provides a cool, reflective backdrop that lifts the medium saturation of the sapphire while harmonizing with the bi color shift. Because the clarity is very slightly included at eye level, the inclusions do not interfere with the overall brilliance, and in fact they confirm the stone s natural origin. At The Natural Sapphire Company we love stones like this because they tell a story through their light, a story that begins in Ceylon s gem gravels and ends on the hand of the person who chooses to wear it, a ring that is both a jewel and a living piece of geological history. If you wish to see how the sapphire s colors move in different lighting conditions, or to discuss the proportions and how they affect the bow tie and scintillation, we are happy to guide you through those subtleties so you can experience the stone fully before you decide.
