Picked these rings up for $5 a piece and wasn't sure if either were gold. As it turns out they are both solid gold and very old as well. The first ring turned out to be 10k with one opal and two rubies! Yes they are two real not synthetic rubies. Obviously the ring has seen better times as the gems themselves are pretty worn but but still make for a nice antique ring. This rings dates from about 1910-1920. Finally is my oldest ring by far! I had this tested at 8k and it definitely is solid! The gem is a rose de France amethyst most likely made in France as well. This ring dates from about 1880-1890 again not the best condition but still an amazing piece and worth a lot more than $5! The ring was tarnished badly when I bought it and with a quick wipe with a jeweler's cloth it came right off and it looks like gold again!
