Vintage Scottish Sterling Silver & 2 Colour Granite Bracelet

Scottish sterling silver and 2 colour polished granite bracelet, the 7 granite plaques are oval and a rosey red colour and a green or gray tint depending on the light. Partially cleaned and nicely toned but further cleaning would make it brighter as the silver is toned. Stamped to the rear with "silver". Period: anytime from the 1920s to the 1950s. A bit of thought has gone into the design as the fittings to the ovals are at a slight angle to allow for the curvature of the wrist a better fit. Maximum usable length 17cm or 7 inches, to make it bigger is easy enough but to make it smaller would require you to lose one panel. All is good.
