Every diamond is worth what someone will pay you for it. You can buy a 25 point diamond -- 25/100ths of a carat -- today at Blue Nile and spend about US$215. A four-point diamond is 4/100ths of a carat, meaning that it is very small for a diamond -- between 2 and 2.5MM at the girdle if the diamond is a round brilliant cut.
Any diamond is worth whatever someone will pay you for it.
