@tmcvintage1: Most people get unsigned costume jewelry wrong. Here’s what to look for: Always turn the piece over and study its construction. Look for signs of assemblage, such as individual stone cups soldered together to create the design. This tells you the piece was carefully constructed—not simply punched from one form. Notice how different stone shapes are layered throughout the design. That dimension and craftsmanship can make a quality piece stand out. Look for unusual stone colors, shapes, and combinations too. This gorgeous brooch is unsigned, but it is a known Juliana piece made by DeLizza & Elster.
