Although some sellers & collectors attribute this piece to Schreiner, I believe it is an unsigned Kramer set, since I have the same brooch in topaz brown colors (also for sale in my shop), and the topaz one is signed by Kramer*. This glorious set is a three-dimensional, domed brooch, inverse or reverse set with pointy sides up of deep sapphire blue and teal emerald green glass stones, all prong set open back in a black, japanned setting.
The brooch measures 1 7/8" inches across and 1" inch high. Each earring measures 7/8" of an inch across. Clips on these function tightly and perfectly. This stunning set is in really superb, excellent condition!
*Designers like Weiss and Kramer produced some signed and unsigned pieces back in the 1950's-60's that were the same item; one was signed for fine department stores and the same piece would be unsigned to place in stores like Woolworth's.
