so here is a unopened paper envelope from the 60s the paper is old and the phone # is only 5 digits ...that is cool .....what I found interesting is E.H Ashley is a old Gems dealer and he got into these stones though a guy named Swarovski which I find interesting because everyone has heard his name now...but this could have been the start of importing demi diamonds I read up and this imitations are made of same material as the natural and are indeed diamonds but instead of 100s of years they could do it in months growing them in labratories.......ok It says 2 Gross and 6 dozen...so we have 360 gemstones approx. for diy jewelers and hobbiests and artists...they just need cleaning from sitting for 60 years..so lets go 20c apiece
