Lovely signed blue topaz earrings in 14K gold & sterling silver

Measuring just under an inch long, these post earrings are made by ATR, a Thai company that often uses this combination of precious metals and stones. The faceted blue topaz centres are rimmed in 14k gold, with an additional silver rope frame. The earrings dangle on interlocking hoops, also in silver rope style. Marked on the open work backs: 14K 925 ATR. These earrings came without post backs so I am including a pair in soft plastic, which are very secure.
