I am about to purchase a round diamond in the $18,000 to $20,000 range. I plan on ordering a diamond from the internet. I would like to narrow my choice down to two or three diamonds, and some how get all of them shipped to me (or any other third party, such as an appraiser) to view and choose between, then return the ones I don''t choose. I am willing to pay $20,000 for the price of one diamond but can''t afford to put up $40,000 to $60,000 to pay for two or three. Is there a way to do this? If so, how?
