pearl identification

[gaylebar1]

Hi, I received these from a jewelry bag at a local estate sale. They are super nice, 100% gritty, a light silver gray and are quite heavy. The pearls do have some scratch/dull areas (probably from being tossed in a bag). Sorry for the regular measuring tape, I don't have MMs. Also no box or history. Thank you

They appear to be dyed freshwater pearls.
