Vintage signed 'Centura' sterling silver, clear paste rhinestone brooch - large size, beautiful condition

Fabulous antique / vintage Edwardian sterling silver and clear rhinestone large floral brooch. This piece is large and completely stunning, packed with, what I assume are, paste rhinestones. The stones are claw / prong set with a unique type of double prong system which I often find in earrings in the same style (some are listed for sale in this shop). The reverse has a stamped patent number and it is marked 'silver' and 'centura', the latter of which may be the company producing and/or retailing the brooch.

The brooch is in very good vintage condition - the stones are lovely and bright with no yellowing or signs of age really at all, which is lovely. The black faux leather presentation box was with the brooch, but was probably not its original box. There is a little discolouration on the white fabric on the interior of the lid.
