14k Diamond, Aquamarine, and Pearl Set

Set of drop pearl earrings and pendant in a 14k white gold setting with aquamarine and diamond stones. The set also includes a sterling silver chain (about 16 inches long end to end when unclasped) to use with the pendant. The pendant, the earrings, and the earring backs are all marked 14k and signed. The makers mark looks to me like it might be Fabrikant, but I’m not certain. According to my kitchen scale the weight of the pendant and earrings is 4.5 grams together, and the sterling chain is about another 2.2 grams.
