I think it would say ctw (carat total weight) if it were .5 total. I'm thinking that they are .5 each...but thats just my 2 cents. Post a picture up
against a ruler or a penny or something that we know the size of. We should be able to look at them and tell you what they are. It should be
a big difference between .5 ctw, or .5 plus .5 = 1 ctw.
so each stud is stamped with normal UK hallmarks but then at the end of the hallmark is the diamond stamp which say 0.50 PTS so i hope thats means there .5 each with a CTW of 1.
Um, those are not studs. My idea will not work (works with studs). Those are clusters.
Are those inches on the tape? If so, it looks like they are fairly large. I would think* .5 each for a total of 1 carat however,
going by the size of the backs (if they are the standard size backs) then I would think* they are .25 for a total of .5.
