This is a modern princess-cut diamond full all-round eternity ring, channel set in platinum with a total weight of high-quality diamonds of approximately 1.3 carats. Most eternity rings today are only set half way round with diamonds, saving money and making sizing possible, but this is the classic all-round ring - to my mind so much nicer. Finger size N - American 6 1/2 - and it cannot be re-sized. I will be happy to quote competitively for other sizes and types of eternity ring.
