This bracelet is an outstanding example of early Mexican silver. It is sterling silver with those wonderful large stones. I am not a gemologist but I believe they are onyx. Each link has a well done roping design around the outside edge and the bracelet has a box clasp. It comes with matching screw back earrings. The jewelry is marked Mexico Silver, an early mark. Bracelet measures 7" long and is just under 1" wide. Earrings are about 3/4" top to bottom. They also have the roping design and are marked Mexico Silver. The bracelet has a safety chain. Together they weigh about 65 grams. Jewelry has old patina and is very well made. It is in excellent condition.
