I'm not sure if these pictures downloaded properly, but...
I have a double strand of what have always been assued to be natural pearls.
They are 10mm, the longer strand is approximately 30" and the shorter is 28". There are 82greesh and 74 pearls respectively. They are gritty, off-round. Each pearl is different, some being distinctly more round than others. Some are nearly smooth, others have dimples, some have wrinkles, and some have what look that small blemishes.
The clasp is 14kthe yellow gold with 8 5pt diamonds and 1 10p diamond, strung on knotted silk. The strands are in desparate need of cleaning and restringing.
These pearls belonged to my great-grandmother and were purchased in the 1920s. At the time, they were a "small fortune." What that was, I am not sure.
Thank you for you expert eyes!
