These eapg, open salts are the "Diamond Ridge" pattern, made by Geo. Duncan & sons glass co., circa 1890. This is a lovely detailed, paneled diamond pattern, with each oval salt measuring 2 1/4 inches x 1 inch. They are in very good condition, with some tiny 'fleabites' here and there, nothing major, they are delightful! This old glass glows yellow-green under uv light to further verify age! Open salts are a fabulous form of Early American Pattern Glass to collect!
