Great pearl tests: gently rub 2 pearls together from your strand... Do they feel like fine sandpaper? or grip? (rub gently both ways) then they are gritty real pearls. If they mostly slide well (sometimes the paint makes them "sticky") then they are painted faux pearls. Finally, with clean pearls, try them against you teeth....gritty? = real. Also look at the drill holes to see if they is paint build-up or loss. My guess is that they are faux... but the value in faux is condition & brand name on the clasp. Hope that helps some.
