1920s Pearl Seed retailer Beads Loose White/Off White Cultured 2mm (?) Round 600+ DIY Jewelry Supply Vintage Victorian

This is a vintage 1920s, loose, 3 strand set of round, retailer cultured, pearl, seed beads. Now you will have to go with me on this one. They are white or off-white in color ( I'm not quite sure) and I believe they are approximately 2mm in size, but I am not an expert. The beads have a tiny, tiny hole which perhaps is 0.2 in diameter (cannot guarantee) and are strung on a very, thin thread. There are 600+ in the bunch and they seem to be in good condition. They originally came from an early, Victorian necklace that broke so now they must find a new life. They are lovely pearls, but you are taking a chance on these babies, as I am not an authority on any of this. There is no return on this item so be sure that if the sizing or anything else differs from what I have stated, it is still going to be ok with you.
