This is a Cartier wedding ring. I lost my original ring and quickly purchased one on Mercari that was listed as authentic, but I was concerned about the differences from my original ring, so I repurchased a new one and am now selling this one. It originally came without a certificate of authenticity. I received it in a beautiful condition, but upon close inspection, there are some minor scratches. I myself wore it for one day. It's a type without rounded edges and has one diamond. There is no personal engraving, but it has the following engravings: Cartier Pt950 47 QW 2816 I can include the original case and box that came with the replacement ring, but please let me know if you don't need them. As mentioned above, I was in a hurry, so there is no certificate of authenticity, but I purchased it at my own risk from a seller who stated it was authentic. Please be aware of this when considering a purchase. - Brand: Cartier - Material: Platinum PT950 - Size: 7 - Engraving: None (personal) Thank you for looking.
