UNDERSTANDING METAL ALLOYS
Pure gold and silver are beautifully soft by nature. To ensure they’re strong enough for everyday wear, they are carefully blended with other metals  creating what is known as an alloy. The hallmark number reveals the purity of the piece, indicating the proportion of precious metal within it.
