Each piece is done by an artisan that is trained by Elaine Coyne and therefore, each and every piece is done the same way fine sculpture is done with heat, torches and fine sweeping of elements that provide the secret formula that allows Elaine Coyne to stand apart from other designers. No painted patina is ever a part of an Elaine Coyne product. One of a kind patina on solid brass. Includes Artist's Bio and Designer Velvet Pouch with Trademark Tag All our Patinas are created with heat and torches, using secret additives making every jewelry piece completely unique. This creates a one of a kind artistry that's a signature of the Elaine Coyne collection.
