Looking at the brooch below, I would have never assigned it as a D&E offering due to the 342(+/-) prongs, especially around the center stone. Seems like there's always an exception or two, so identifying Juliana often comes down to experience and familiarity with specific designs. The second photo shows another exception to a common D&E attribution that it must have a 5-panel or 5 link design. It looks more like Hobe than D&E. I thought this would be constructive for this group. Books work! 😅
