Vintage sterling silver white NIELLO enamel bangle bracelet with boat scene

This item shows wear comparable to age. It is marked sterling silver. Safety chain is missing. Clasp is fully functional. 2-3/4” closed; just a little over half an inch wide It is not marked Siam but it is very similar to one it very well may be. But cannot say for sure. Great item for any antique jewelry collector ! Thai Motif This was found in my grandmother’s jewelry box. I know nothing else about it. This item may very well be antique. I do not know.
