When I look at this...all I see is a magnificent piece of history...circa 1910's, light flows through this huge, faceted purple glass stonec...the craftsmanship of this piece shows the early influence of the art nouveau period with in the detail of scrolled metal set in warm gold tone metal has a bit of wear, given it's age it's appropriate. It has a 'C' clasp and measures approx. 3" x 2".
