Complete Description
A platinum three-stone engagement ring featuring a 9.85-carat emerald-cut Ceylon sapphire flanked by two triangle-cut diamonds totaling 2.15 carats. The center sapphire is AGI-certified natural Ceylon (Sri Lankan) origin — one of the most prestigious sapphire origins in fine jewelry — accompanied by an IGI report (certificate 1116533) documenting its specifications.
The triangle diamonds on either side step outward from the center sapphire, framing the colored stone with white brilliance. The geometric pairing — emerald cut sapphire flanked by triangle cuts — references Art Deco design tradition, made distinctive by the rare scale of the center stone.
Why Ceylon sapphires
Ceylon (now Sri Lanka) produces some of the most prized sapphires in fine jewelry, known for their saturated cornflower blue color, excellent crystal clarity, and natural light. The "Ceylon" designation on a sapphire indicates not just origin but a specific tonal range and quality standard. At 9.85 carats, this is a substantial example of the Ceylon tradition — most Ceylon sapphires in fine jewelry are under 5 carats.
How it wears
A 9.85-carat center sapphire in a three-stone setting is statement jewelry — best suited for milestone purchases, engagement rings, or anniversary pieces rather than daily wear. The emerald cut sapphire reads with the long parallel facets characteristic of step cuts, balanced by the angular brilliance of the triangle diamond sides. Platinum keeps the metal cool and modern, letting both the sapphire's blue and the diamonds' white carry the visual story.
For pairing, this ring stands on its own — at this scale, additional jewelry should be quieter. A thin platinum band, simple diamond studs, or a delicate tennis bracelet complement rather than compete.

The center sapphire is natural, mined in Sri Lanka (formerly Ceylon) — one of the most prestigious origins for sapphires in fine jewelry. Sri Lankan/Ceylon sapphires are known for their saturated cornflower blue color, excellent crystal clarity, and natural light return. The origin is documented on the AGI grading report that accompanies this ring.
AGI is the American Gemological Institute, an independent laboratory that grades and certifies gemstones. The sapphire ships with an AGI certificate documenting its origin (Sri Lanka), carat weight (9.85ct), cut (emerald), and color characteristics. Additionally, the ring includes an IGI report (Certificate 1116533) for cross-reference. Both reports are provided with the ring and are suitable for insurance documentation.
Triangle-cut diamonds are a traditional pairing for emerald-cut center stones in three-stone settings. The angular geometry of the triangles complements the rectangular emerald cut of the center sapphire, and the brilliance of the triangle cuts contrasts beautifully with the step cuts of the sapphire. This is a classic high-jewelry combination dating to the Art Deco era of the early 20th century.
Yes — three-stone sapphire rings have a strong engagement ring tradition, particularly since Prince William proposed to Kate Middleton with Princess Diana's blue sapphire engagement ring. They're also worn as milestone anniversary pieces or right-hand statement rings.
