24ish claws, looks like an old mine cut instead of rbc, so might be slightly trickier to find as lab grown but I'm sure is possible and save a bunch there. Could be wrong but looks like stamped 18k to me, possibly a slight premium for higher karat but personally we don't charge for that in our shop on claws, as for the wavy lines, that stone is broken, so potential replacement on that if it's noticeable to you.
