I love when my clients bring in old or unused yellow or white gold. It makes their next piece with me extremely affordable. The gold in a piece is a large chunk of the price so if you already have the gold laying around the house it is a great option to reuse into a new piece that you will wear.
1- The major reason why melting down old gold is a great idea is the savings you will receive. You couple save thousands by using your own metal. (Excluding Platinum)
2- I have a melting process where my clients can come in and watch me melt the gold in front of them. This is a free service that suits my clients with a sentimental connection to the gold they had handed down to them. Which leads me to the next reason.
3- Sentimental value by far is the greatest reason why you should reuse gold that has been handed down to you. The same gold will be used in your rings so it is a great feeling when looking down at the finished product and a memory of a loved one is there with you every day.
