This diamond ring is beautiful. The five diamonds of approximately .50 carats sitting on a scroll work of 18K yellow gold makes this a gorgeous ring. There is no gold karat weight stamp but it tests 18K. I wish I knew of the exact age of this ring besides it just being old. The ring is a sizeable 5 1/2 and weighs 2.97grams. The clarity of the diamonds appear to be I2. The center diamond has a small cut above one of the prongs as if the jeweler got to close in grinding off the tip of the prong but is not really noticeable. There are 16 facets on the crown and 8 on the pavilion.
