This is a beautiful and rare vintage 10K gold Long Island University College key fob charm or pendant that is jeweled with a synthetic/lab created aquamarine gemstone. This piece is exceptionally crafted and the aquamarine has vibrant color. I have done an online search for LIU gold charms and pendants and no results turned up.
Lab-created gemstones are considered real because they are not much different from the natural ones and will test as the gemstone specified.
