Sterling silver and turquoise hummingbird charm necklace

Sterling silver and turquoise hummingbird necklace. This charm was purchased at a turquoise store in New Mexico. The charm is turquoise and sterling silver. The turquoise on the hummingbird appears lighter than the picture in some areas. The charm didn’t come with the chain and I put it on this chain. I’m not sure if the chain is sterling silver. You can wear whatever chain you like with it. The back of the hummingbird is marked sterling and shows some wear. The charm measures approximately 1.5 inches in height. The chain shows some discoloration in some areas and it’s longer and clasped. Reasonable offers welcome.
