This stunning 3-piece ring set by Dazzling Rock features 30 natural blue and white diamond stones set in sterling silver. The channel-set design creates a beautiful and secure setting for the diamonds, which have a total weight of 0.50 carats. This ring set is sizable, with a current ring size of 7.5, and is stamped 925 silver. The round shape of the main diamond stones adds to the classic and timeless design of this ring set. It would make a perfect addition to any jewelry collection or a special gift for a loved one. The quality and craftsmanship of the rings are evident, and it is sure to be a treasured piece for years to come. There was little information given with these rings when I purchased them from Amazon, so unfortunately, I cannot give many details about them. I am selling them because they no longer fit my fingers and I didn't want to pay for three ring sizings. They are in great like new condition because they were hardly worn.
