Real vs Fake Tiffany Knot: How to Spot a Fake

Real vs Fake Tiffany Knot: How to Tell If Yours Is Real

A fake Tiffany Knot copies the crossed bars and the wrapped knot well enough to pass in a listing photo, so the shape tells you little. Here is how to tell if Tiffany Knot is real: read the stamps on the small oval chain tag near the clasp. On the authentic tags in this guide, ©TIFFANY&Co. is evenly spaced with a round o, and Au750 ITALY stands upright. Then match the piece against Tiffany's own listing.

Tiffany & Co. launched Tiffany Knot in the US on September 7, 2021, in 18k yellow and rose gold, with stores worldwide following in 2022. The launch release tied the design to the chain-link fences of New York. Today's product pages tell a different story, an archival bow crafted in 1889. Tiffany's US site listed the plain Tiffany Knot pendant in 18k yellow gold at $3,300 in July 2026, on an adjustable 15-17 inch chain. The fake vs real Tiffany Knot comparison below starts on the chain, not on the pendant.

How the Tiffany Knot Differs From Other Tiffany and Designer Jewelry

The Knot pendant hangs from a fine cable chain with a small oval tag near the clasp. The cards in this guide show a logo stamp in one photo and a gold standard stamp in another. That is a different setup from the heart tag and toggle in our Return to Tiffany necklace real vs fake guide, where the tag is the design itself. Tiffany HardWear, the chunky link collection, gets its own guide. Knot rings and bangles have no chain, so their marks sit on the piece itself, and the tag checks below apply to the necklaces. A Tiffany Knot bracelet fake or real question, or a Tiffany Knot ring fake vs real one, starts with the same habit: find every stamp and compare its type with a confirmed piece of the same style. Other houses mark their gold differently again, so the lettering tells you nothing across brands. Compare our Cartier Juste un Clou bracelet guide, our Van Cleef Sweet Alhambra bracelet guide and our Hermès Clic H bracelet guide.

Why the Tiffany Knot Is Heavily Counterfeited

The Knot is a simple, graphic shape in solid 18k gold, and the cheapest plain pendant costs thousands of dollars new. A gold-plated copy can share the outline and sit next to genuine listings at a fraction of the price. The diamond versions add pavé, which looks convincing in a small photo whether the stones are diamonds or not.

Jewelry is the most valuable counterfeit category seized at the US border. In the U.S. Customs and Border Protection fiscal year 2024 seizure statistics, jewelry ranked first by retail value at about $1.65 billion, with 713,036 items seized.

The photos in this guide come from several confirmed authentic and counterfeit pieces, and the tag photos show the chain only, not the pendant it hangs from. I describe what separates each pair of photos, not a rule that every fake follows.

TIFFANY & Co. Logo Tag Lettering

Both chain tags read ©TIFFANY&Co. The difference is how the stamp is cut. On the authentic tag the serif capitals stand apart with clear gaps, the o is round and the line ends in a small round period. On the counterfeit the letters press into each other, the o is a narrow oval and the text fills the field from end to end.

• Letter spacing. Every letter of TIFFANY on the authentic tag has daylight on both sides. On the counterfeit the Y, the ampersand and the C run into each other.
• The o in Co. Measured on the photo, the authentic o is close to round, nearly as wide as it is tall. The counterfeit o is only about two thirds as wide as it is tall, and much narrower than its own C.
• The period. The authentic line ends in a small round dot sitting apart from the o. The counterfeit dot trails a tail below the line, so it reads like a comma.
• Margins in the oval. The authentic text leaves about one letter height of empty field at each end. The counterfeit leaves a sliver, about a quarter of a letter height.
• Overall length. Scaled to the same letter height, the counterfeit line is clearly shorter than the authentic one, so the fake squeezes the same words into less room.

Photograph the tag square-on with the whole oval in frame. An angled shot squeezes the letters and hides the margins.

Au750 ITALY Hallmark Tag

Au750 means 750 parts per thousand gold, which is 18 karat, the metal Tiffany lists for the Knot. Any caster can stamp those five characters, so read the type, not the number. On this pair the Tiffany Knot hallmark tag sets Au750 ITALY in upright serif type. The counterfeit stamps Au750 alone, and every character leans right like italics.

• Upright vs slanted. The authentic A, u, 5 and 0 stand straight. On the counterfeit every character leans right like italics. The counterfeit tag sits a few degrees off level in its photo, tilted the other way, so the lean is in the type, not the camera.
• Wording. The authentic line continues with ITALY. The counterfeit stops after Au750. The next section explains why that alone decides nothing.
• What not to read. The authentic stamp is lit bright on a dark ground and the counterfeit dark on a bright ground, so stroke thickness and the gaps between characters look different for lighting reasons. Measured center to center, the two lines are spaced about the same.

Turn the tag over, or check the next tag along the chain, to find the gold standard stamp and photograph it square-on. Our free hallmark checker explains what each gold and silver mark means before you compare the type.

Country Line on the Hallmark Tag

The authentic tag in this guide adds ITALY after Au750, and the counterfeit tag has no country at all. That difference is a prompt, not a verdict. Tiffany runs its own jewelry workshops in the United States, and I found no Tiffany source saying every Knot chain is made in Italy, so a genuine Knot may carry a different country line.

• Tiffany makes jewelry in the US. Its last annual report filed with the SEC, for fiscal 2019, lists company-owned jewelry plants in Cumberland, Rhode Island and Lexington, Kentucky. A tag without ITALY is not a fake by itself.
• Read it together with the type. A missing country line counts only when the Au750 lettering is also wrong. On this pair it was: every character slanted.
• Ask about the chain. A replacement chain from another maker can carry that maker's marks, so a mismatch between the tags and the pendant engraving needs an explanation from the seller.

Photograph the hallmark tag from end to end so the whole line, including any country, is readable.

Tiffany Listing for Your Piece

Tiffany's own product page lists the facts a counterfeit has to match: the metal, the chain length and, for diamond pieces, the carat total weight. The plain Knot pendant reads 18k yellow gold, on an adjustable 15-17 inch chain, and features a Tiffany & Co. hallmark. A match shows the details belong together, nothing more.

• Metal. Every Knot listing I found on Tiffany's US site was 18k gold, in yellow, rose or white, and some diamond pieces pair rose gold with platinum. A Tiffany Knot sold as plated or as sterling silver matches none of them. Resale sites also list older Tiffany silver pieces with a knot motif, such as Love Knot designs, which belong to other collections.
• Item number. Each Tiffany page carries an item number, 68887194 for the plain yellow gold pendant on the US site. A receipt with an item number lets you open the exact listing instead of guessing the variant.
• Chain length. The plain and diamond pendant listings I checked give an adjustable 15-17 inch chain. Other Knot necklaces use other lengths, so compare with the listing for your exact item. A pendant on a chain that matches none needs an explanation, such as a later replacement chain.
• Carat weight. Diamond pendants carry a stated carat total weight, .25 on the yellow gold pendant with diamonds on Tiffany's Canadian site in 2025. A seller who cannot name it for a diamond piece has not looked at the paperwork.

Save the Tiffany page for the exact piece and compare it line by line with the seller's description and photos.

Seller, Receipt and Blue Box

Tiffany's counterfeit FAQ lists where new Tiffany jewelry is sold: its own stores and websites, plus Net-a-Porter and Farfetch for select collaboration styles. A new Knot from any other shop is secondhand at best. The Blue Box, which Tiffany says dates to 1886, and the pouch travel separately from the jewelry, so packaging cannot prove the piece inside.

• Tiffany does not authenticate. Its FAQ says it currently does not offer an authentication program, so a seller who claims Tiffany verified a piece needs to show how.
• Receipts. A Tiffany receipt or order confirmation that names the Knot and its metal ties the piece to a purchase. Ask for it with the price and personal data covered.
• Boxes and pouches. Genuine packaging is easy to buy on its own, so judge the tags first.

Photograph the receipt next to the necklace and its chain tag, so the paperwork and the piece appear together.

Red Flags That End the Inspection

On this Tiffany Knot comparison, the logo tag is the finding I would stop on. A ©TIFFANY&Co. stamp with letters running into each other, a narrow o and text crammed against both ends of the oval cannot be rescued by a correct Au750 or a Blue Box.

• A crowded logo stamp. Touching letters and no margin at the ends of the oval put the whole necklace in doubt.
• A slanted hallmark. Au750 in characters that lean right like italics does not match the upright stamp on the authentic tag.
• A metal Tiffany never listed. A Tiffany Knot, the 2021 collection, described as sterling silver or gold plated matches no Tiffany listing I found.
• A price far below resale. Price is not proof, but it is the reason to ask for photos of both tag stamps first.

Not red flags on their own: rose versus yellow gold, how shiny the metal looks in a photo, a correct Au750 stamp, and the presence of a Blue Box. Each one varies between genuine pieces or is easy to copy.

What Current Superfakes Get Right

The counterfeits in these cards are not crude. They copy the crossed bars, the two-wrap knot, the angled bar tips and the pavé rows on the diamond version. They carry a correctly spelled logo tag and an Au750 tag.

What these Tiffany Knot counterfeits still miss is how the marks are cut. The words and numbers are mostly right, but the letter spacing, the shape of the o and the slant of the hallmark are not. That is where the fakes in this guide show themselves.

Copying a word is easy, copying a stamp's proportions is not. How to spot a fake Tiffany Knot at this level comes down to comparing the tags at the same size against a confirmed piece. The same habit works on other gold pieces with small stamps, as our Cartier Love ring guide shows.

What You Can Check Yourself and What You Cannot

The listing check and the seller check transfer well through a written guide, because they have fixed answers on Tiffany's own pages. The tag lettering is harder. It is a judgment about how a stamp is cut, and it needs a confirmed Tiffany Knot photographed at the same angle to compare against.

Tags wear, get polished and get replaced with the chain, and a genuine piece made in another country may carry a different country line. A tag that differs from the one in this guide is not automatically fake. When we review Tiffany jewelry from customer photographs at LegitGrails, at least two specialists compare each stamp against confirmed pieces of the same collection.

Frequently Asked Questions

How can you tell if a Tiffany Knot piece is real?

Start with the marks, not the shape. On a Knot necklace, photograph every stamped face of the oval chain tag near the clasp square-on. On the authentic tags in this guide, ©TIFFANY&Co. is evenly spaced with a round o and empty margin at both ends, and Au750 ITALY stands upright. Then compare the metal, chain length and item number with Tiffany's own listing.

Tiffany Knot real vs fake: what should I check first?

Check the logo tag first. On this pair the counterfeit spelled ©TIFFANY&Co. correctly but crowded the letters until they touched, narrowed the o to about two thirds of its height and ran the text into both ends of the oval. Those proportions are harder to copy than the wording, and they show in one clear photo taken straight on.

Where is the hallmark on a Tiffany Knot bracelet?

Tiffany's listings say Knot pieces feature a Tiffany & Co. hallmark, but they do not say where it sits. On the necklaces in this guide, the marks shown are on the small oval chain tag near the clasp. A bangle or ring has no chain, so its marks have to be on the piece itself. Photograph every inner surface and the clasp area, and compare with a confirmed piece of the same style.

What metal is a real Tiffany Knot made of?

18k gold. Tiffany launched Knot in 2021 in 18k yellow and rose gold, and its US site now lists yellow, rose and white gold, with some diamond pieces pairing rose gold and platinum. The mark Au750 means 750 parts per thousand gold, which is 18 karat. Counterfeits stamp Au750 too, so the mark only helps when its type matches a genuine stamp.

Does a real Tiffany Knot come in a blue box and pouch?

Tiffany ships its jewelry in the Blue Box, packaging the brand dates to 1886, and its FAQ lists its own stores and websites, plus Net-a-Porter and Farfetch for select styles, as the places to buy new. Boxes and pouches can be bought on their own on the resale market, though, so a box proves nothing about the necklace inside. A Tiffany receipt naming the piece is stronger, and the tags still decide.

Tiffany Knot dupe vs real: what is the difference?

A dupe is a lookalike sold under its own name with no Tiffany marks. A counterfeit carries Tiffany's name or hallmarks on a piece Tiffany did not make, which is what the fakes in this guide do. Neither is Tiffany's 18k gold. If a necklace shaped like the Knot is stamped TIFFANY&Co. and the price is far below Tiffany's, treat it as a possible counterfeit, not a dupe.

Is an Au750 stamp proof that a Tiffany Knot is real?

No. Au750 only states a gold standard, and the counterfeit in this guide carries it on its chain tag. What separates the pair is how the stamp is cut: upright on the authentic, every character leaning right on the counterfeit. Tiffany does not offer an authentication program, so an independent check of the stamps is the practical route.

Does a Tiffany Knot have a serial number?

Tiffany does not list one. Its Knot pendant listings say the piece features a Tiffany & Co. hallmark and mention no serial number, and the genuine tags in this guide carry the logo on one tag and Au750 ITALY on the other, with no number. The number on a Tiffany product page identifies the design, not your piece. A number engraved on a Knot is not a verdict either way, so judge the tags.
