Freshwater Baroque Pearl and Sterling Necklace

Lovely freshwater baroque pearl & quartz (I believe) necklace and earring set. The pearls are in beautiful champagne & light gray shades w/ the characteristic unique shapes of baroques. 925 Sterling stamp on the last photo. I did not polish the silver chain portions between the stones bcse I didn’t want to do any damage to the stones. This is high-quality, not costume, but I can’t remember if these are some type of quartz stones, or crystal. I believe they are champagne quartz. Adjstble lngth.
