We are interested in purchasing wholesale lots of opal doublets and triplets. The opal component of these gems should be natural. The sizes need to be calibrated, total volume that we require is over 5,000 pieces. We are on the lookout for regular vendors who can steadily replenish our stocks, the idea is to build a longterm relationship. We expect wholesale prices and assure a mutually beneficial relationship.
