Vintage Platinum 1.07 Carat Marquise Diamond Three Stone Ring

Platinum marquise diamond ring, circa 1980s, designed with a 1.07 carat marquise cut center diamond accented by tapered baguette diamond side stones. The elongated center diamond is set in a classic platinum mounting with protective pointed end prongs, allowing the marquise shape to sit prominently across the finger. The tapered baguette diamonds are set along each shoulder, adding a clean architectural line that complements the center stone without overpowering the design. The ring is stamped PLAT, indicating platinum, and reflects the refined three stone engagement ring style popular in the late 20th century. The ring weighs 3.4 grams and is a size 7.25. Its low profile shank and balanced setting give the piece a traditional, elegant presentation. Light surface wear is present throughout, consistent with age and estate condition.
