Do you provide a certification for silver purity?

All our products are stamped with "92.5" to indicate the purity of silver i.e. 92.5% silver. The only exceptions to this are some of our small nose pins that are too small to be stamped even though they are also made with 92.5% silver. 

Elements like posts for earrings, clasps for brooches, nose pin wires, or ghungroos will have an 85% silver mix, to ensure the requisite strength for these elements.
