Frequently Asked Questions


How often are the auctions performed!

Auctions are held every two weeks, as holidays permit.  The 5-day auctions start on Wednesday and end the following Monday.


How Long does the auction process take?

Auctions will normally begin the first and third Wednesday of every month at 2:00pm EST and will end on the following Monday at 02:00pm EST.  The auction submission deadline is the Monday prior to auction start, so the entire process takes about 10 days.

Which jewelry items can be submitted for auction?

Any item with a center diamond larger than 0.40ct. can be submitted for auction.  However, any other gold or platinum item can be submitted for direct purchase, even if it doesn't contain any diamonds.

What do you do with the jewelry that is submitted for auction?

Your jewelry is shipped to our diamond grading and evaluation auction facility.  As soon as the items are received, they are inspected and verified.  They are also photographed, graded and cataloged in preparation for the auction.  You will receive notifications via email and you will be able to review your item's status during the entire process.


Is my jewelry insured?

Your jewelry is fully insured during the entire process up to the value stated in your auction submission form.

Are there any fees involved?
