Silver Pendant with Blue Stone and Chain in 830S

Vintage silver pendant with a large facet-cut blue stone and matching chain. The geometric design has a clear Art Deco-inspired character. The pendant is hallmarked 830S. The stone has not been identified and is therefore referred to as a blue stone.

The silver has natural patina and minor, normal scratches. The stone appears intact in the photographs, with no visible chips. The chain has been tested with XRF, but the alloy result has not been specified, so this is not stated in the listing text.
