Pure silver butterfly pin / brooch by Victor Pereyra.
Creating the piece in pure silver, which is softer than sterling, allowed Victor to create wonderful detail on the butterfly by piercing a pattern on the butterfly's wings.
As you know, pure silver is .999 and sterling is .925. Because this is made using pure silver, the piece will not tarnish as easily as sterling since sterling has a copper alloy in it which causes the metal to tarnish over time.
The clasp that is attached to the pin is marked "925", which gives the piece a secure pin, therefore, the "925" stamp is not indicative of the silver content of the pin itself, but rather the clasp that is attached to each piece.
