I am very fond of the Tiffany Victoria earrings (the ones with four marquise diamonds). Is this a unique design by Tiffany? The reason for asking is that I saw a well known jeweler with earrings in the very same design and I would like to know if this jeweler has made earrings "inspired" by Tiffany or if it is a design that has been around for ages, even long before the Tiffany Victoria collection.
