3.00 Carat Round Brilliant Diamond Engagement Ring in Platinum | Vintage-Style

A round brilliant diamond commands the center, held in a domed platinum mount where pierced scrollwork and milgrain edging build outward around it rather than sitting flat against the finger. Smaller diamonds trace the openwork in a repeating pattern, catching light in scattered points that frame the center stone without competing with it. The bombé shape and filigree detailing draw on early-20th-century design language, giving a substantial, dimensional presence rather than a simple prong setting. The piece shows no visible wear, tarnish, or damage. Ring size 6.25, weighing 10 grams, set with one round brilliant diamond weighing 3.00 carats, H color, I1 clarity, and 64 round brilliant diamonds totaling approximately 0.35 carats, G-H color, VS2 clarity.
