Bilaminated Angels.
Bilaminated pieces are pieces that undergo a double plating process (in 925 silver laminate) which gives them an appearance that is identical to any silver piece but at a more attractive price. These are pieces that, as a general rule, have a special finish that makes them resistant to the elements, not requiring cleaning with silver products (which, if used, could damage them). Just wipe off the dust with a flannel cloth and they will maintain their original look for a long time.
