Once the diamond buyer has received your diamond ring, it will be given to a diamond expert to have graded. After the diamond ring has been graded, a valuation will be placed on it and they will contact you with the offer. You will be contacted either through email or a phone call and you will have a certain amount of time to either accept or deny the offer. If you choose to deny the offer, your diamond ring will be sent back to you at no charge. If you accept their offer, you can choose to have a check sent to your home or have the money wired into a bank account
