This is such a sweet little cluster ring set in the popular daisy style.  With eight diamonds set around the centre diamond all in millegrain mounts.  Approximate diamond content 0.20-0.25ct.  Raised pointed shoulders to a yellow gold band stamped "18ct" and testing as 18ct gold.  Finger size K with some resizing possible, it's the perfect engagement ring for a petite hand.
