I have always wanted a Tiffany’s diamonds by the yard single diamond necklace but could never justify the price. I have a diamond necklace that I would like to redesign into the Tiffany style. However, I don’t have the original paperwork for the diamond necklace and I’m scared that the diamond might be swapped for a more cheaper one in the redesigning process (was told by a friend to be careful) without my knowledge.
any recommendations for any reputable jewellers who do this? And what sort of a price range I’m looking at.
