    Tip for Authenticating Tiffany Jewelry

    One of the biggest names in the jewelry business is Tiffany & Co. After all, who doesn’t like getting a gift in a little blue box? In addition to the new pieces being popular, secondhand, vintage Tiffany jewelry is much-loved too. However, when you purchase these older pieces, you can put yourself at risk of buying a “fake”—if you’re not careful. We have put together a brief guide to help you with the authentication process so that you can buy with confidence.


    The logo has changed over the years, but the name should always be listed as either Tiffany & Co. or T & Co. Check online to compare the logo to other pieces from the same era to find out if the article in question uses a similar logo styling to see if it is “to date.”


    The engraving should be high-quality. Although the older pieces may not have the same precise etching of today, it should still be clean and neat. Additionally, if it is a signed piece, it should be signed by one of the known signers. These include Jean Schlumberger, Paloma Picasso, Elsa Peretti and Frank Gehry.

    The quality of Craftsmanship

    Tiffany & Co. is known for their attention to detail and excellent craftsmanship. This includes little details like clasps, the backsides of pieces and settings. If a piece seems cheap or poorly made, it’s probably less-likely to be genuine.

    The Quality of Materials

    In addition to being well-made, Tiffany jewelry is also going to include quality materials. Gold and silver will be stamped with the appropriate lettering for its purity and diamonds, and jewels will have the sparkle of a high-quality piece.

    Paperwork and Package

    While not every vintage or used article will include paperwork, documentation or box, this can be an excellent way to verify whether the piece is genuine. Higher end pieces come in a dark blue box, while standard pieces have the “regular” blue box that is known worldwide. Tiffany & Co. diamonds were originally sold with a diamond dossier with is a trusted form of certification.

    Finally, the best thing you can do is to both buy and sell Tiffany jewelry to a reputable jeweler. When you choose to work with an expert, instead of an unknown, you know you are in good hands.
