What happened to imperial gold company also sold on QVC?

In 2004 Imperial Gold stopped producing their jewelry line. They continued servicing their warranty repair work until 2010. At that time the company that provided IG gold with their supplies for repair stopped producing the line. They were unable to get the same quality gold for their repairs, so they discontinued the warranty service. Any pieces of jewelry sent to IG Gold for repair after December 2010 is being sent back to the customer.
