Offering this beautiful, platinum bombé cobblestone ring featuring a 1.1 ct genuine antique old mine cut center diamond surrounded by a stunning cobblestone arrangement of natural diamonds. The ring features a unique combination of polished platinum and blackened metal, creating beautiful contrast and highlighting the antique character of the diamonds. The craftsmanship and intricate detailing make this a truly special piece. **Ring Details** Metal: Platinum with blackened metal accents Total Diamond Weight: 3.42 carats, natural diamonds Center Diamond: Approximately 1.10 ct genuine antique OMC diamond, GIA certified Ring Size: US 4.75 Condition: Excellent with minor scratches I purchased this ring in August 2026, and it has been very gently worn. It is in excellent condition. I’m selling because I’ve realized my personal jewelry preferences are evolving and am leaning more towards lower profile rings/something with less finger coverage. I’d love for this beautiful piece to find a new home where it will be appreciated and worn. I’m happy to provide additional photos, videos, and a copy of the GIA report upon request. **shipping to continental US only!**
