Silver vine leaf and Peridot ring

This ring is gorgeous in person. I love the vines and the leaves detail. And the peridot are so beautiful. I bought it from Silver Chic, but I do not see the 925 stamp on it. I am confident it is silver. However, I cannot swear to it without the stamp. It does act like silver and was bought from a silver dealer. The ring is a 6 1/2 to 6 3/4.
