Vintage Tiffany & Co. Jewelry: How to Date It, Authenticate It, and What's Worth Buying

By Sasha Tarasova

Filed under Hallmarks, Dating & AuthenticationDesigner & Signed JewelryBuying Guides

Short answer: vintage Tiffany jewelry is dated and authenticated mainly by its marks, construction and weight: the form of the signature ("T & Co." or "Tiffany & Co."), the metal stamp (925, 750, 18K), any designer name such as Elsa Peretti or Jean Schlumberger, and the quality of the engraving and soldering. A Tiffany box proves nothing. Final authentication belongs to Tiffany or a qualified specialist.

Tiffany is one of the most counterfeited names in jewelry, and also one of the most rewarding to collect. The two facts are connected. This is how we read a piece when it lands on our bench, what separates the real thing from the rest, and which vintage Tiffany is actually worth your money. For the record: ZHIVA is an independent dealer. We are not affiliated with, authorized by or endorsed by Tiffany & Co., and we use the name here only to describe the house's pieces.

What makes vintage Tiffany jewelry different from new?

Vintage Tiffany differs from new mainly in marking, construction details and scarcity: discontinued designs cannot be bought new at all, and the metal and design you want may simply no longer be made.

A note on vocabulary. In the trade, "vintage" usually means roughly 20 to 100 years old, "antique" means 100 years or more, and "estate" simply means previously owned. Our guide to antique, vintage and estate jewelry sets out why those words matter when you are reading a listing. Most Tiffany on the secondary market is vintage or recent estate, not antique.

A short history of Tiffany & Co.

Tiffany & Co. was founded in New York in 1837 by Charles Lewis Tiffany and John B. Young, originally as a stationery and fancy goods store. Jewelry, silver and the reputation that goes with both came later.

Four dates matter to a buyer:

• 1837 — the founding in New York. Anything claimed to be earlier is not Tiffany.
• 1851 — Tiffany adopted the sterling standard of 925 parts silver per 1,000, and is widely credited with establishing it as the benchmark for American silver. This is why "925" and "Sterling" sit at the centre of Tiffany silver marks.
• 1886 — the house introduced the Tiffany setting, a six-prong solitaire mount that lifts the diamond above the band. Its influence on the modern engagement ring is hard to overstate, and it is part of the background to choosing a vintage engagement ring today.
• The Blue Box — the robin's egg blue now known as Tiffany Blue has been associated with the house since the nineteenth century and is a registered trademark. It is also among the most copied pieces of packaging in jewelry, which is exactly why it cannot be used as evidence.

In the twentieth century the house brought in named designers who gave it a second identity. Jean Schlumberger joined in 1956. Elsa Peretti began designing for Tiffany in 1974. Paloma Picasso followed in 1980. Their names are signed on their pieces, and that signature is part of what you are buying.

How do you read Tiffany hallmarks?

Tiffany hallmarks combine a house signature, a metal fineness stamp and, on designer pieces, the designer's name. Read them in that order, and read them for quality as well as content: a genuine mark is crisp, evenly struck and correctly spelled.

If you are new to marks in general, start with our guide on how to read a hallmark. Tiffany is an American house, and American jewelry has no compulsory state assay system of the British kind. The marks are the maker's own. In the United States, the FTC Guides for the Jewelry Industry (16 CFR Part 23) govern how metal content may be described, and federal stamping law requires a maker who stamps a quality mark such as "18K" or "Sterling" to stamp its trademark alongside it. On Tiffany, the house signature is that trademark.

The house signature

You will see two main forms. "Tiffany & Co." in full appears where space allows. "T & Co." is used on small parts: jump rings, clasps, earring backs, small charms. Seeing the abbreviation is not a warning sign in itself. Seeing it poorly struck, crooked or with an oddly shaped ampersand is.

The metal stamp

• 925 or Sterling — sterling silver, 92.5% pure. On many pieces the two appear together.
• 750 or 18K — 18 karat gold, 75% pure. Pieces made for different markets may carry either, or both. "750" is the European fineness number; "18K" is the American karat form.
• PT950 or similar — platinum, found mostly on diamond pieces.
• Combined marks such as "925 & 750" — mixed-metal pieces, usually silver with gold accents. These are legitimate Tiffany production and should not be mistaken for "gold".

Designer signatures and the © symbol

Designer pieces are usually signed with the designer's name alongside the house mark: "Elsa Peretti" or "Peretti", "Paloma Picasso", or "Schlumberger" together with "Tiffany & Co.". Many carry a copyright symbol followed by a year.

That year is the single most misread mark in the Tiffany market. A © date is the date of the design's copyright, not the date the piece was made. A Peretti design copyrighted in the 1970s may have been manufactured for decades afterwards, and every example carries the same year. It can tell you a piece is not older than that date. It cannot tell you it is that old.

How to tell if Tiffany is real

You tell if Tiffany is real by checking construction and marks together, never marks alone. Counterfeiters copy the words; they are much worse at copying the metalwork and the weight.

The checklist we work through:

1. Read every word of the engraving under a 10x loupe. Spelling, spacing, the shape of the ampersand, the serifs. Errors such as a doubled letter or a missing space are common on fakes and essentially absent on genuine pieces.
2. Look at the depth and evenness of the stamps. Genuine marks are clean, sharp-edged and uniform in depth. Shallow, blurry or uneven stamps, or stamps that look pushed into soft metal, are a warning.
3. Check the soldering. On Tiffany chain and bracelet work, jump rings and links are normally soldered closed. Open or gapped jump rings, visible solder blobs or porous seams suggest a copy or an amateur repair.
4. Weigh it. Solid silver and solid gold have weight. A fake is often noticeably lighter than a genuine piece of the same model. Compare against a verified example or published weight where one exists.
5. Look for colour under the surface. Wear at edges, clasps and the back of tags can reveal brass or copper beneath plating. Solid sterling and solid gold are the same colour all the way through.
6. Test the metal. A magnet should not pull on silver or gold, though passing the magnet test proves little on its own. An acid or XRF test by a jeweller confirms fineness; it does not confirm maker.
7. Check the clasp and findings. Findings on genuine pieces are well finished and consistent in quality with the rest of the piece. Cheap, rough or mismatched clasps are a common giveaway.
8. Ask for provenance and a return policy. A receipt, repair record or a documented history strengthens a piece. A seller who will not accept a return after independent authentication is telling you something.

No checklist replaces handling the piece, and none replaces the house. If a significant amount of money depends on it, the final word comes from Tiffany or a qualified specialist who has examined the object. Our guide to buying antique jewelry online safely covers how to structure a purchase so that you can get that opinion before you are committed.

Return to Tiffany bracelet: real vs fake

A real Return to Tiffany bracelet has deep, crisp, correctly spaced engraving, solid weight, soldered links and a quality clasp; a fake usually fails on engraving, weight or finish. It is one of the most copied Tiffany designs, so it deserves its own section.

Where the design came from

The Return to Tiffany concept began in 1969 as a key ring. The tag was engraved with "Please Return to Tiffany & Co. New York" and a registration number, so that a finder could send lost keys back to the store and Tiffany could reunite them with their owner. The idea later moved from the key ring onto bracelets, necklaces and earrings, and it became one of the house's best known designs. Heart tags, round tags and oval tags all exist.

What to check on a Return to Tiffany piece

• The tag engraving. Letters should be evenly spaced, deep and clean-edged, with a consistent baseline. Fakes often show letters that crowd together, wander off line, or look scratched rather than cut.
• The tag itself. A genuine tag is substantial, with a well-finished edge and a smooth, even surface. Thin, flimsy tags with rounded, mushy edges are typical of copies.
• The links. Soldered closed, uniform and smoothly finished. Look at the ring that holds the tag as closely as you look at the tag.
• The marks. Consistent with the metal: 925 on silver, 750 on 18k gold. A gold-coloured Return to Tiffany piece stamped only 925 is silver or gilded silver, not gold.
• The overall weight. One of the most reliable tells, and one sellers of fakes avoid stating.

Silver-plated tags and "gold" that isn't

Cheap silver-plated copies are the most common fake. They are usually base metal with a thin silver finish, and they betray themselves with wear: a yellowish or coppery tone showing through at edges and high points. The gold equivalent is worse, because the price difference between silver and gold is larger. If a listing says "gold Return to Tiffany" and does not state the fineness mark and weight, assume it is plated or silver until proven otherwise.

Why is gold vintage Tiffany so much rarer than silver?

Gold vintage Tiffany is rarer because far less of it was made, and it costs more because each piece contains a significant weight of 18k gold on top of the design premium. Silver was the house's volume material for designs like Return to Tiffany; gold was the exception.

A useful example: the vintage Return to Tiffany heart tag bracelet in 18k yellow gold we currently hold weighs 33.0 grams. That weight is part of the point. A comparable silver bracelet is a fraction of the price, for good reason.

Judge the metal and the maker separately, then together. If you are building towards a collection rather than buying a single piece, our guide on starting a collection without getting burned is the place to begin.

Do Tiffany boxes and pouches prove authenticity?

No. A Tiffany box, pouch, card or shopping bag proves nothing about the piece inside it. Genuine packaging is sold separately on the secondary market, and counterfeit packaging is made in volume alongside counterfeit jewelry.

Packaging has value as a courtesy and as part of a complete set, and a buyer may reasonably pay a little more for a piece that comes with its original box. But we have seen convincing boxes around unconvincing silver, and genuine pieces with no box at all. Judge the object. A seller who leans on the packaging while being vague about marks, weight and returns is using the box to do work the jewelry cannot.

The same goes for paperwork that cannot be tied to the specific piece. A receipt that matches the description, date and item is useful. A generic care card is not. Our article on what a real dealer should disclose sets out what documentation you should expect to be offered without asking.

What vintage Tiffany jewelry is worth buying?

The vintage Tiffany most worth buying is signed designer work, earlier and discontinued pieces, and anything in gold from lines usually made in silver. Mass-produced current silver is the least interesting: easy to find new, heavily faked, and priced close to retail at best.

Jean Schlumberger

Schlumberger's pieces for Tiffany are the house's most sculptural jewelry: gold, enamel, gemstones and a naturalist imagination. His name appears alongside the Tiffany signature. Vintage Schlumberger is collected seriously, and condition matters a great deal, especially on enamel, which is difficult to restore invisibly.

Elsa Peretti

Peretti's organic forms, such as the bean and the open heart, defined Tiffany design from the 1970s onward. Much of her work was produced in silver in large numbers, which is why silver Peretti is common and gold Peretti is more desirable. Discontinued Peretti designs and pieces in gold or unusual materials draw the strongest interest.

Paloma Picasso

Paloma Picasso's designs for Tiffany are bold and graphic, and signed pieces from the earlier years of her collaboration are collected. As with Peretti, the metal and the rarity of the specific design matter more than the name alone.

Early and unusual pieces

Older Tiffany jewelry, including Art Deco and mid-century gold, is scarcer than twentieth-century designer silver and should be assessed like any other period jewelry: design, materials, condition and originality first. The Tiffany name adds a premium, but it does not rescue a heavily altered piece. If you are looking at a pre-war diamond ring attributed to the house, the same rules apply as in our guide to spotting a reproduction Art Deco ring.

Gold Return to Tiffany

Among the more recent Tiffany lines, 18k gold Return to Tiffany pieces are the ones we would single out. The design is instantly recognizable, and the gold versions are far scarcer than the silver.

Is vintage Tiffany jewelry a good investment?

Vintage Tiffany jewelry is not an investment in any strict sense, but signed gold and designer pieces tend to hold value better than unsigned jewelry of the same materials. Silver pieces rarely resell above what you paid.

Gold pieces have a floor set by metal value; signed Schlumberger, Peretti and Picasso have their own collector base; common silver trades below retail and moves with fashion. Any resale also carries a dealer or auction margin you must recover before you are ahead.

Buy it because you want to wear it. If value retention matters to you, our frank assessment of whether antique jewelry is a good investment explains what holds up and what doesn't. Once you own a gold or designer piece, have it appraised and insured properly; our guide to insuring antique jewelry covers appraisals and riders.

How to buy vintage Tiffany safely

Buy vintage Tiffany from a seller who states the marks, the weight and the metal in writing, offers a return window long enough for independent authentication, and does not rely on packaging as proof.

1. Ask for close-up photographs of every mark, in focus, under good light. A seller who cannot supply them should not be trusted with the rest.
2. Ask for the weight in grams and compare it with verified examples of the same model.
3. Get the metal and fineness stated in writing, not implied. "Tiffany gold bracelet" is not a description; "18k yellow gold, stamped 750 and Tiffany & Co., 33.0 grams" is.
4. Confirm the return policy covers failed authentication, explicitly.
5. Ask about repairs, resizing and replaced parts. Replaced clasps and non-original chains affect value and should be disclosed.
6. Pay with a method that gives you recourse. Wire transfers to unknown private sellers give you none.
7. Have it independently examined within the return window if the price justifies it.

Good signed pieces often come out of private collections and do not always reach a public listing. You can browse what is available now in our current collection, or join the Vault for early access to new signed pieces before they are listed.

Questions people actually ask

Is all genuine Tiffany jewelry marked?

Genuine Tiffany jewelry is almost always marked with the house signature, either "Tiffany & Co." or "T & Co.", and a metal fineness mark such as 925 or 750. Marks can be worn down by decades of polishing or lost during resizing, but an unmarked piece described as Tiffany needs strong documentation, such as an original receipt, before it should be priced as Tiffany.

What does T & Co. mean on jewelry?

"T & Co." is the abbreviated Tiffany & Co. signature, used where space is limited: jump rings, clasps, earring backs and small charms. It is a normal genuine mark, not a warning sign. What matters is how it is struck. Genuine marks are crisp, straight and evenly deep; blurry, shallow or oddly shaped lettering, especially the ampersand, suggests a copy.

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

Check the tag engraving under a loupe for even, deep, correctly spaced lettering; confirm the links are soldered closed; weigh the bracelet against a verified example; and make sure the fineness mark matches the metal, 925 for silver and 750 for 18k gold. Plating wear showing a different colour underneath is a clear sign of a fake. Final authentication belongs to Tiffany or a qualified specialist.

Does the copyright year on Tiffany jewelry show when it was made?

No. The © year on Tiffany designer pieces, such as Elsa Peretti or Paloma Picasso designs, is the year the design was copyrighted, not the year the piece was made. A design may have been produced for decades with the same date. The year tells you the piece cannot be older than that date, but not how old it actually is.

Why is gold Return to Tiffany so much more expensive than silver?

Tiffany made far fewer Return to Tiffany pieces in 18k gold than in sterling silver, so gold examples are scarce on the secondary market. Each gold piece also contains a substantial weight of 18k gold, which sets a real floor under its price. Silver versions are plentiful, heavily counterfeited and usually resell below retail.

Does a Tiffany box mean the jewelry is real?

No. Tiffany boxes, pouches and cards are sold separately on the secondary market and are counterfeited in volume. Packaging adds a little to a complete set, but it proves nothing about the object inside. Judge the piece itself: marks, weight, construction and metal, and buy from a seller whose return policy covers failed authentication.
