These Russian 50 Roubles coins were a one year issue coin that was minted in 1993. The coin was part of a set of coins Russia issued that featured Wildlife, Sea life and Birds. This coin featured the beautiful Egret, I do two versions of this coin and this is by far the nicest one for the Earrings. After cutting the Earrings are plated in 14 Karat Gold and Rhodium, They are a perfect size and weight for earrings measuring 3/4″ in diameter. We mount hem on 14 Karat Gold Filled ear Wires.
