Whether you are designing the perfect engagement ring that must speak to a lifetime of commitment, or you are a collector seeking a standout gem to anchor a cabinet of fine stones, this sapphire meets those needs.

The way a sapphire is cut determines how it performs under real light, in everyday settings and under the most forgiving displays. This gem features an oval shape with a mixed brilliant cut, a choice that combines the scintillating fire of brilliant cutting with the elegant proportions of an oval outline. The mixed brilliant facets have been executed to create a balanced return of light, so the stone shows both lively sparkle and deep internal glow. The polish is excellent, so light glides across the surface and each facet edge contributes to the overall performance. At eye level the stone is evaluated as eye clean, meaning inclusions do not disturb the visual purity, and that characteristic is essential when you want a gem that reads as flawless in wear. The color is vivid, with an intensity that commands attention without overwhelming. In a ring or a pendant, this sapphire will be the centerpiece, catching glances and elevating any setting with a strong, saturated presence.

For clients who want full clarity on enhancements and treatment, transparency matters as much as the gem itself. This sapphire has been heat treated, a standard and widely accepted enhancement that improves color and clarity while remaining stable and permanent under normal wear. Heat treatment is a common practice in fine gemology, and done properly it brings out the best in stones from Ceylon and other classic sources. The result here is a vivid blue that benefits from the island s characteristic mineralogy, a tone that works beautifully with both warm and cool metal choices. The mixed brilliant cut further magnifies color saturation in a way that is flattering for most skin tones, and the size at just under 4 carats gives you substantial presence without making the piece difficult to wear daily. For collectors, the combination of Ceylon origin, eye clean clarity at 3.94 carats, and a masterful polish offers a gem that will sit well within a curated grouping, and for couples seeking an engagement stone, it promises a bold and enduring statement.
