With Clarity has the best diamond prices. However, if you do find the same diamond (IGI or GIA certificate number must match), for a lower price on another retailers website, we will match that price. Note, that the diamond must be the same and the price must be published to the live link on the website. With Clarity reserves the right to verify and check on the diamond availability, price and link. The diamond must be available to purchase on the comparative retail site.
