How do they determine the total ct weight of a pave?

[Sizzle]

do you think the tiny diamonds are weighed before hand or do they "guesstimate" by mm size?

manufactures weigh the diamonds before they are set into mounting.An appraiser may measure the mm size and then give an approximate carat weight.Some appraisers will have one stone removed and weighed then give an approximate weight.
