Thank you for viewing. This is a half-eternity ring featuring a brilliant 1.00ct diamond. Actually, diamonds are set for more than half (180°) of the ring. The material is 18K white gold. It has no snags, and the metal is not visible from the top, making it easy to pair with either gold or silver, and any stone. It's built very sturdily, so it shouldn't deform easily. It weighed 4 grams on a kitchen scale that displays in single digits. This is just for your reference. The size is size 15. It will be delivered in simple packaging. Please consider it.
