SELL YOUR JEWELRY
SELL YOUR JEWELRY AND LOOSE DIAMONDS
Schedule an appointment to sell your jewelry and loose diamonds at either of our stores.
We will buy your diamond outright, by check or cash. You can also sell your diamond by consigning it in our store.
SELLING YOUR LOOSE DIAMOND ON CONSIGNMENT
To get the highest price on your loose diamond, we can sell it for you by consignment in our store. We will agree on a price during your appointment.
As soon as your diamond sells, we will send a check to you by overnight express. This is a great option, if you don’t need the money right away.
BEST PRICE POLICY
Our goal is to provide you the best price and quality available anywhere.
If you see a lower price prior to purchase for a comparable item, we'll beat it.
**Must be verified prior to purchase.**
