White Gold Diamond Ring 18k

Im selling my white gold diamond ring that I bought in the middle east. It features a round cut and the weight of the gems is DIA - 0.18 CT. The clarity grade is SI and the colour grade is G. The gold purity is 18 KT, with a gold weight of 2.58 GRM. Size 6. It's been stored in my jewellery box so decided to sell it. I offer a money-back guarantee if it's proven to be fake.
