This gorgeous cruciform brooch in opaque and translucent blue stones is unsigned, but clearly designer quality and with the tiered, reinforced construction similar to Schreiner or Austria. Because of the all-closed backing, I lean toward Austria. Measures 2 1/8". Each stone is individually pronged in, with the chatons collet-set. Goldtone plating. Condition is excellent apart from some of the translucent blue stones aren't as brilliant as they probably were brand-new. This is not conspicuous and is probably a picky observation.
