Last time I went to the beach I found lots of coins, 10k and 14k rings and these 2 matching set earrings that have me a little confused. When I found the first one my excal gave me that sweet low mellow tone and when I dug it up I figured white gold. Two steps later I found the other one with the same tone. Got home and couldn't find and gold markings but did find what looks like 925 on one side and pas on the other side. Rechecked on my excal and got the same low tone, ran them across my G2 and got a 52 reading indicating gold. Did gold test and it passed the 10k test. Also tried the silver acid and the scratches went away but the color didn't change. Am I doing something wrong or are these fake, certainly not silver according to the tones and reading on G2? Tried to get a pic of the 925 but doesn't look too clear. One weighs 1.67 grams and the other 1.57 grams, They are a little bigger than a penny and smaller than a nickle. Thanks for looking. John
