The listing, yellow pearls has ended.
real yellow pearls ready to make a beautiful necklace,
looked this particular set of pearls up online and found this information:
Real pearls would have been strung on silk thread and knotted between each pearl to stop them rubbing together and protect against breakage.
Stringing on cotton or twine with or without knots isn't a good omen.
so knowing that these pearls were in a small bag and box and belonged to my great aunt, I would assume they are authentic. texture tested and I believe may be of value to the right person who has time to buy the proper string and restring them.
