Thursday, September 15th, 2011

      Wife Kaye recently worked with a local family to renovate this heirloom bracelet, composed of sterling silver panels, strung on a ribbon, each hand engraved with the initials of a family member.

Saturday, September 3rd, 2011

  Our client sadly thought this family heirloom .96 ct. Old European cut diamond had little or no value– after years of wear, it had been cherished almost to death and looked like it had been through the garbage disposal. Mardon to the rescue!
