How would you respond if this happened to you?

  If a customer entered your store with a gemstone not knowing its worth and you have an idea of its value, what do you do?

  This happened to a client of ours last month.  Mark Wania of L Guess in Whitton, Middlesex.  He suggested that his customer take the item to Sotheby's to get it correctly valued.  The diamond then sold for £650,000!  How would you respond in the same situation?  We feel karma has a way of responding, whichever way you turn.  If you want to share your thoughts please click here and we'll post your response below.  If you'd like to know how the BBC covered the story, then please click here.
