Laura Ramsey designer green cabochon gemstone gold plated solid sterling pendant

This is an amazing Laura Ramsey designer green cabochon gemstone gold plated solid sterling pendant. The center gemstone is real and has tiny inclusions in it, but I don’t know what it is. The two side stone are made of CZ (cubic zirconia). It is stamped LR for Laura Ramsey, and 925 for sterling silver. The pendant weighs 5.7 grams. It comes with a 16 inch gold tone metal chain with a 2 inch extender chain and black silk cord. In excellent vintage condition.
