If the jewelry store you go to is a well-known brand, the high price is normal, which is called brand added value. If you go to a less well-known jewelry store, you can cut off the tall one, and you can buy pure gold within 500, with a discount of more than 300. If it is inlaid, it's hard to say. It depends on the size and technology of the diamond.
