I might warn you that the wanted/for sale section specifically states only billiard related items have a cash price. All non-billiard related items should be offered only for trade for billiard related items as per the sticky.
Just forwarning you that this post could be deleted or asked to be changed due to offering cash prices for non-pool related items.
Like most things diamonds are worth a fraction of retail price, especially now in this economy. This posting wont be here long as it has nothing to do with pool!
