A lovely goldtone dome-shaped brooch that reminds me of a blue cone-flower daisy. The tips of the 'petals' curve slightly toward the domed center.
It is marked ©LISNER on the back, near the pin hinge. I have tried to capture the mark, in the last photo, but it is very difficult to get a good photo. The sapphire-blue stones are all present, and undamaged, as is the goldtone finish. It looks as though it has never been worn, although it could use a good cleaning. I leave that to you.
It measures approx 1 7/8" across, top of dome sits about 5/8" above pin back. Clasp is intact, and works perfectly. It will be packaged in a gift box.
The Lisner Company ceased production in 1968.
