MATERIAL : Silver on top and backed with 14K gold
TECHNIQUE : Silver on gold. This technique finds its origin centuries ago, when jewelers believed that only a silver mounting could render the true beauty of a diamond. Backing the silver jewel with a (thin) layer of gold was a practical precaution taken to avoid the silver jewelry leaving black stains on clothing or skin. Over the years, with the recognition (and thus use) of platinum as precious metal and the development of white gold the practical necessity to use bi-colored material became obsolete. The argument to use bi-colored metals became more an estetic then a practical one.
