There absolutely won't be another one of these - it's absolutely mint - never worn - only one I have - high polished silver plate with a large acrylic very detailed blue eye. Inside dimension is 5.5" with a soft flex ruler. Opening is another 1/25" across - whereas this piece is NOT sterling silver it is pretty rigid with no flexibility. This one comes from my old Luxor hotel line and was originally a slave bracelet. I have modified this one as the ring could not be salvaged. It's now a unique original one and only piece. Gemmy.
