To calculate these prices you must multiply the carat weight. 1 carat is the easiest of course because it literally equals what is listed. a 1.35 carat is multiplied by the $6,500 rate + 8,775 vs the 1 carat $6,500. This is how you calculate the prices. This is the pricing you typically see at retail stores.
