GM 925 Silver Cross Necklace Simple design Turquoise color Beads 12 inches long

Downsizing my personal collection-I am not sure where I got this cross from. I believe it was a gift. I have never worn it. The smooth silver cross is approx 1 1/4 inch long, 1 inch wide. It is stamped on the back, GM 925 China. The clasp is marked GM 925 with China on the back. Photos included with this listing. The length is 12 inches. The turquoise colored beads look plastic. Questions welcomed. Thank you for your consideration.
