I do not engage in melting or casting with customer-provided metal. However, if you want to order jewelry in gold and have unwanted gold pieces, you can use them to reduce the cost of gold. This is done as follows: 1. You send me your old gold jewelry. 2. I send them for refining - the process of purifying metal from impurities. In simple terms, your jewelry will yield pure 999-grade gold. 3. We can then use this gold for your new piece, reducing the overall cost. As gold is an expensive metal, this method allows for a significant reduction in the cost of the final piece.
