This is a modern Rose cut diamond ring, but the diamonds are still set in silver, as tradition requires,  and the shank is 14 ct gold. The size is p-g, and the wide band is pierced. I bought this a while ago, but with Covid, it was not till now that I have seen Kathryn, our in-house diamond technologist, to test the diamonds and confirm them. In an age of rose cut synthetic moissanites*, fracture filled stones etc, one needs scientific confirmation. 7.8 grams in total.

*Synthetic moissanites test as diamonds with the old biro type diamond testers.
