10K Yellow Gold and Pearl Pendant

This elegant 10K gold pendant features a lustrous pearl, perfect for adding a touch of sophistication to any outfit. Not marked anywhere that I can see (there may be something on the side of the bail but I can’t make it out), I purchased it from someone who said they tested it electronically and I have tested it with acid to confirm that it’s 10k. Quarter for scale, about 1 cm long. 0.85 grams.
