Tiffany & Co. does not authenticate or appraise jewelry, so a pre-owned Return to Tiffany tag, Bean or Open Heart has no brand check behind it, and Blue Boxes are easy to fake. Our Tiffany authentication service examines stamps, purity marks, designer signatures, engraving, links, clasps, settings and finish.

I have used Legit Grails to authenticate purses and jewelry. Their site is easy to navigate and they have great support and pricing. I would recommend them to anyone needing to authenticate high end name brands.

What we check on Tiffany & Co.
How to tell a real Tiffany & Co. from a fake
On a Return to Tiffany piece, the heart tag engraving is the decisive check. Copies usually get the silhouette right and fail on engraving, stamps and how the piece is put together.
01
Tag and plaque engraving
The arc across the top of a Return to Tiffany heart, level lines, even stroke depth and a gap at both ends of the plaque lettering.
02
Brand stamp
Tiffany & Co. or T & Co. in the right font, depth and place for the piece.
03
Purity mark
925 on sterling, 750 or AU750 on 18k gold, 950 or PT950 on platinum, judged on how the characters were formed.
04
Designer signature
Elsa Peretti, Paloma Picasso or Schlumberger signatures alongside the Tiffany name.
05
Links, bail and clasp
Links of one gauge, a bail formed as one loop and a clasp tag in matched capitals with rounded ends.
06
Edges and finish
Rolled edges on tags, even polish and no plating wear showing a different metal underneath.
07
Setting and stones
Evenly set stones and clean prongs on rings and pavé pieces.

Read your Tiffany Hallmarks
Tiffany pieces are usually stamped with the house name and the metal, such as T&Co. 925 for sterling silver, and some carry a designer signature such as Elsa Peretti or Paloma Picasso. Our free checker reads these marks. Stamps are easy to copy, so have the piece authenticated by our experts.
Authenticated. For Charity.

No. Tiffany & Co. says it currently does not offer an authentication program. Upload photos here and a professional authenticator checks your piece against verified Tiffany references, with a certificate you can share with a buyer, a seller or a marketplace.
Only for diamonds. Tiffany issues its own Tiffany Diamond Certificate for its diamonds. Silver and gold pieces usually come with a pouch, a box and a printed card, and that card has no serial, so it certifies nothing on its own.
No public one. Silver pieces are usually marked with the Tiffany name and a fineness stamp, not a serial. Return to Tiffany tags carried a registry number from the late 1960s, while the silver tags introduced in 1997 have 925 and no number. Our free hallmark check reads Tiffany stamps, but stamps can be copied.
Look at the heart tag first. On a real tag a curved line arcs across the top of the heart, the lines sit level and the final period is a separate round dot. Fakes often drop the arc or merge the dot into a letter. Then check the plaque lettering, the clasp tag and the bail.
No. Counterfeits arrive with pouches and printed cards too, so packaging proves nothing, and a 925 stamp is only as good as the tool that struck it. We judge how the stamp was formed and check the engraving and construction of the piece itself.
Yes. Ask the seller for sharp close-ups of the tag or pendant front and back, every stamp, the clasp, the links and the bail, and upload them before you pay. A professional authenticator checks them against verified Tiffany references and gives a verdict with a shareable certificate.
For the most accurate and quick authentication process, we advise you to upload clear photos of the areas visible when clicking 'Upload photos' on this page.
