How to Tell If Tiffany Jewelry Is Real: Return to Tiffany, Tiffany T and Elsa Peretti

Short answer: to tell if Tiffany jewelry is real, check the marks, the engraving, the construction and the weight together. Genuine pieces carry a crisp "Tiffany & Co." or "T&Co." signature and a fineness mark that matches the metal (925 for sterling, 750 or AU750 for 18k gold), with deep, even engraving, soldered links and a solid weight. Return to Tiffany, Tiffany T and Elsa Peretti designs each have their own tells, covered below. A blue box proves nothing.

Tiffany is counterfeited more than almost any other jewelry name, and three lines account for most of what we see: the Return to Tiffany tag, the Tiffany T and Elsa Peretti's Bean and Open Heart. They are popular, recognisable and relatively simple in form, which makes them attractive to copy and, at a glance, easy to get wrong.

This is the focused companion to our longer vintage Tiffany guide, which covers the house's history, how to date pieces and which vintage Tiffany is worth buying. Here we stick to one question: how to check whether the piece in front of you is genuine.

What marks should real Tiffany jewelry have?

Real Tiffany jewelry is marked with the house signature, either "Tiffany & Co." in full or "T&Co." on small parts, and a fineness mark: 925 or Sterling for silver, 750, AU750 or 18K for 18k gold, and a platinum mark such as PT950 on platinum. Designer pieces add the designer's name, and many recent pieces add a country of manufacture.

Check the marks for quality as well as content:

• Crisp and evenly deep, with clean edges, not shallow, blurred or pushed into the metal.
• Correct spelling and spacing, with a well-formed ampersand. Doubled letters and odd gaps are classic fake errors.
• Fineness matches the metal. A yellow piece stamped only 925 is silver, gilded silver or a fake, not gold.
• Placement makes sense, on the back of a tag, a clasp, a jump ring or inside a band.

A mark is a claim, and counterfeiters copy marks first. Our guide to how to tell if silver is real explains what 925 does and does not prove about the metal.

How can you tell if a Return to Tiffany piece is real?

A genuine Return to Tiffany piece has a substantial tag with deep, even, well-spaced engraving reading "Please Return to Tiffany & Co. New York", soldered links, a well-made clasp, fineness and house marks that match the metal, and a weight appropriate to its size. Fakes usually fail on the engraving, the tag thickness or the weight.

The design began in 1969 as a key ring tag engraved with a return address, and it later moved onto bracelets, necklaces and earrings in heart, round and oval forms. Check it in this order:

1. The engraving. Under a 10x loupe, letters should be deep, cleanly cut and evenly spaced on a steady baseline, in a typeface consistent with verified pieces. Crowded, wandering, shallow or scratchy lettering is the most common giveaway.
2. The tag. Genuine tags are thick enough to feel substantial, with crisp, evenly finished edges and a flat, smooth surface. Thin, flexible tags with soft, rounded edges are typical of copies.
3. The links. Uniform, smoothly finished and soldered closed, including the ring that holds the tag. Open or gapped rings suggest a copy or an amateur repair.
4. The marks. T&Co. or Tiffany & Co. with 925 on silver, or 750 or AU750 on gold, struck cleanly.
5. The weight. Ask for grams and compare against verified examples of the same model and size.
6. The colour under wear. Yellow, pink or coppery metal showing through at edges means plating over base metal.

Gold Return to Tiffany pieces are much scarcer than silver ones, and the most expensive to get wrong. Our vintage Return to Tiffany heart tag bracelet in 18k yellow gold weighs 33.0 grams; weight like that is one of the first things we check on any gold tag bracelet, because plated copies cannot match it.

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

A genuine Tiffany T piece has a sharply defined, symmetrical T motif with clean, flat surfaces and crisp edges, precise stone setting where stones are used, and marks consistent with the line, typically the Tiffany & Co. signature, the metal fineness and often a country of manufacture. Many Tiffany T pieces are marked "ITALY".

Tiffany T was launched in 2014, so every genuine piece is recent, and quality expectations are those of contemporary high-end production. Look for:

• Geometry. The T bars should be straight, even in width and precisely aligned. Soft, wavy or slightly asymmetric forms are warning signs.
• Finish. Clean polished surfaces, sharp transitions and no porosity, tool marks or uneven plating colour.
• Stone work. On pieces with gemstone inlay or pavé, inlays should fit tightly with no glue line or gaps, and small diamonds should be evenly matched and secure.
• Hinges and clasps. On cuffs and wire bracelets, the opening mechanism should feel precise and close securely.
• Marks. Clean, correctly spelled and consistent with verified pieces of the same model.

Our Tiffany T turquoise and diamond circle pendant in 18k gold is a good example of what to look for: a turquoise inlay held cleanly behind the T, a ring of small diamonds, and marks reading Tiffany & Co., ITALY and Au 750. Each of those features is something a copy has to reproduce, and inlay fit and pavé quality are where copies usually fall short.

How can you tell if Elsa Peretti Tiffany jewelry is real?

Genuine Elsa Peretti for Tiffany pieces are signed with the designer's name, usually "Elsa Peretti" or "Peretti", alongside the Tiffany signature and a fineness mark, and many carry a © symbol with a year. The forms are fluid and precisely finished, and the shapes are distinctive enough that proportions alone often expose a fake.

Peretti began designing for Tiffany in 1974. Her most copied designs are the Open Heart and the Bean:

• Open Heart. The genuine heart is an organic, slightly asymmetric form, its line swelling and thinning as it curves. Fakes are often stiff and symmetrical, like a heart cut from a template, with uniform wire thickness.
• Bean. The genuine bean is smooth, evenly polished and seamlessly contoured, with a neat attachment to its chain. Visible seams, lumps, pitting or a clumsy bail suggest a copy.
• The © year. It records the design's copyright, not the year of manufacture, so it cannot date a piece, only set the earliest possible date.

Because Peretti silver was made in large numbers, most fakes are silver or plated imitations. Gold Peretti pieces deserve extra scrutiny, including weight and an XRF test.

What are the common signs of fake Tiffany jewelry?

Most fakes give themselves away in the same few places, line by line.

Do the blue box and pouch prove Tiffany is real?

No. Blue boxes, pouches, cards and shopping bags are sold separately and counterfeited in volume, and genuine packaging is routinely paired with fake jewelry. Packaging is a pleasant extra on a genuine piece and no evidence at all on its own.

Paperwork is useful only when it can be tied to the specific piece: a receipt from a named Tiffany store that matches the item and date, or a service record. The same principle runs through every signed house, as our guides to authenticating a Cartier Love bracelet and telling if a Van Cleef Alhambra is real show.

Why should a jeweler test Tiffany jewelry?

Because a jeweler can confirm the metal quickly and without damage, which eliminates the large share of fakes that are plated base metal. An XRF analyser reads the alloy at the surface in seconds without marking the piece; an acid test needs a small filed spot and is better avoided on signed jewelry.

What testing cannot do is confirm the maker. Better counterfeits are made in genuine sterling silver or even 18k gold, so a correct metal reading is necessary but not sufficient. Construction, engraving, finish and weight have to agree with the metal. Our explainer on signed versus unsigned jewelry covers why the signature carries so much of the value, and therefore why it is so often forged.

How should you buy pre-owned Tiffany safely?

Buy from a seller who states marks, metal and weight in writing, shows clear photographs of every mark, and offers a return window long enough for independent checking. Then do the checks yourself.

1. Identify the line and model and find verified examples to compare.
2. Read every mark under a loupe for spelling, depth and placement.
3. Weigh the piece and compare with verified examples.
4. Inspect construction: engraving, links, inlays, stones, clasps and hinges.
5. Look for plating wear at edges and high points.
6. Have the metal confirmed by XRF at a jeweler.
7. Ignore the packaging in your decision.
8. Get an authenticity guarantee in writing, with a full refund if a specialist disagrees, and pay with buyer protection.

Questions people actually ask

How can you tell if a Tiffany necklace is real?

Check that the pendant and clasp carry a crisp Tiffany & Co. or T&Co. signature and a fineness mark matching the metal, such as 925 or 750. Inspect engraving depth, link soldering and stone setting under a loupe, compare the weight with verified examples, and look for plating wear at the edges. Then have the metal confirmed and, for valuable pieces, consult a specialist.

What does the Return to Tiffany tag say?

The tag is engraved "Please Return to Tiffany & Co. New York", a reference to the original 1969 key ring, which allowed a finder to return lost keys to the store. On genuine pieces the lettering is deep, cleanly cut and evenly spaced on a steady baseline. Shallow, crowded or wandering engraving is one of the most common signs of a fake.

Is Tiffany jewelry marked ITALY real?

It can be. Many recent Tiffany pieces, including much of the Tiffany T line, are marked with a country of manufacture such as ITALY alongside the Tiffany & Co. signature and a fineness mark. The country mark does not prove authenticity by itself, since counterfeiters copy it too. Judge it together with construction, finish, weight and the other marks.

How do you spot a fake Elsa Peretti Open Heart?

A genuine Elsa Peretti Open Heart has a fluid, slightly asymmetric shape in which the line swells and thins as it curves, and it is signed with Peretti's name, the Tiffany signature and a fineness mark. Fakes are often stiff and perfectly symmetrical, with wire of uniform thickness, weak marks or no designer signature at all.

Does a Tiffany blue box prove the jewelry is real?

No. Tiffany boxes, pouches and cards are sold separately and counterfeited in large numbers, and genuine packaging is often paired with fake jewelry. Packaging adds a little to a complete genuine set but proves nothing about the piece. Judge the jewelry itself: marks, engraving, construction, weight and metal, and buy where returns cover failed authentication.

Can a jeweler tell if Tiffany jewelry is real?

A jeweler can confirm the metal quickly, usually with a non-destructive XRF test, which exposes plated fakes. A jeweler cannot confirm the maker from metal alone, because better counterfeits use real sterling silver or gold. For signed pieces of significant value, consult a specialist in signed jewelry who examines construction, engraving and marks in person.
