This well preserved antique bangle bracelet is stamped “PRST CO” for Providence Stock Company and therefore was likely produced in the early 1900’s. It is gold filled and has 4 opals in ornate settings. It has a wonderful oval shape when clasped, but with a simple press of a button at one side of one hinge the bracelet opens up to a circle for easy on & off. The clasp and hinge work well. The piece shows some flaws in the finish that you can see in the photos. It could use a good clean & polish.
