The custom made rings do not have a metal mark but were tested with nitric acid and a AuRacle tester to be solid 14k yellow gold. Together they weigh 13.1 grams. It is hard to explain the set but one fits snugly up against the other. They both have a floral antiqued design. Set in the middle of the inner ring is a round brilliant cut natural diamond with an approx weight of .33 cts. It is SI2 and H color. The ring also has a round small natural diamond set to one side. The rings wear to a size 8.5 and can be resized.
