Decoration: Other stones Color: Blue Material: Platinum Pt900 Size: Approximately size 8. It has a beautiful sapphire surrounded by melee diamonds, and I think it's very cute. Please refer to the engraving for the carat of the stones. As this is not a store, I may not be able to answer specialized questions. The above information is from the store at the time of purchase and from the engraving. Previously, there was a request for cancellation after receiving a jewelry item, and I was very confused because of the possibility of substitution. If you want the same guarantee, appraisal, etc. as a store, please purchase from a store. No cancellations. Stone: Sapphire
