Your answer depends on the chips. Some chips can only be used as abrasives to cut and polish other diamonds; other chips -- rather large chips -- can be cut and polished into smaller gemstones. Every diamond is valued individually by its cut, clarity, carat weight and colour.
One carat of diamond in a single diamond is worth more than multiple diamonds -- or chips in this case -- is worth. Any diamond is valued by its cut, colour, clarity and carat weight. Anything is worth whatever someone will pay you for it. You can take your chips to a jeweler who makes jewelery and sell them there.
Fifteen carats of diamond chips is a large total weight for chips: unfaceted diamonds. The total weight is almost one-tenth of an ounce. There is no standard by which to evaluate diamond chips. You are best advised to take the jewelery to a jewelery maker and ask for a valuation.
