If you wanted just one (pendant)... I would have said: give yourself time (= quite a bit) and try for a keshi pearl of acceptable shape and color somewhere in the 'golden' range.
A whole strand of such ... unless seed-like small... I wouldn't know if it is reasonable to ask for at all. I have seen two overall, and the look may not be what you expect (very baroque, misshapen pearls most of them, and very strongly graduated and also very, very cherry priced).
Golden baroques sounds a w e s o m e !
