The pearls I purchased from the collection of Marie-Claude Lalique granddaughter of Rene Lalique. They were part of a cache of gems left over from his days as a jewelry designer. I would very much like to find a way to make a pair of earrings out of them but without drilling them so as not to damage the "historical" nature of them. I was thinking of some sort of cage findings but I'm clueless as to where I might find some. They range from 9.5 to 10.4 mm. Any recommendations would be very much welcome!
