- 1Visit the Tiffany & Co. store and view the piece you are interested in purchasing elsewhere. Take note of the craftsmanship, any engraving or details, the weight of the piece and the overall appearance, including luster and shine.
- 2Visually inspect the piece you would like to purchase. Note any differences between the piece you are holding and the piece you viewed at the Tiffany & Co. store. Many times fake Tiffany jewelry will have a very high shine or luster, making it easier to spot a fake.
- 3Check the piece for tarnish and sterling silver stamp (if sterling silver). A tag should be attached to the clasp stamped with "925" if your piece is authentic Tiffany & Co. sterling silver. The piece should not show any signs of tarnishing.
- 4Compare the weight of the piece to the weight of the item in the Tiffany store. If the piece noticeably weighs less than the one in the store, it is likely a fake.
- 5Review the details. Look at the engraving, polish and curves of the piece. Look at all the finishing touches ... are edges ragged or smooth? Does the piece look high-quality and made with good craftsmanship? Do you notice differences between the two pieces? If so, you are likely viewing a fake Tiffany & Co. item.
- 6Is the price too good to be true? Is someone trying to sell you an "authentic" Tiffany necklace for $20 that is brand new and in perfect condition? This likely isn't a bargain, it is a knock off.
