Do you have an older piece of jewellery which needs attention?
Every part of an old worn piece can be restored.
Often the cost of this exceeds the value of the piece and a full remake could be less expensive. But you may want to retain that item without a total melt-down and redesign. You may even prefer to reset worn and chipped stones rather than replace them.
This can show the true value of an heirloom or sentimental piece.
You are welcome to consult me on how this may be done for your particular item and what options are available.
