Why Elsa Peretti Is a Collection, Not a Single Model
Elsa Peretti has designed for Tiffany & Co. since 1974, and her sculptural, organic silhouettes (Open Heart, Bean, Teardrop, Bone Cuff, and a dozen smaller lines) are some of the most resold jewelry designs on the secondary market. That volume is exactly why this guide covers the collection rather than one piece: across hundreds of authenticated Elsa Peretti submissions we've reviewed, the fakes cluster overwhelmingly around three designs, Open Heart, Bean, and Teardrop (specifically the Teardrop Bypass Ring), while everything else in the line shows up too rarely among counterfeits to support its own checkpoint.
The counterfeits also don't fail where most buyers expect. The hallmark, "TIFFANY & CO. © Elsa Peretti 925 [SPAIN]," is reproduced convincingly on both genuine and fake pieces we've compared side by side, so a clean, correctly worded stamp proves close to nothing by itself. What actually separates the strongest fake we've examined from genuine production is proportion: an Open Heart pendant sized and chained the way Tiffany has never sold one. That's a check almost anyone can run without a loupe, which is the angle this guide leads with.
What to check, ranked by reliability
| Checkpoint | Reliability | What it tells you |
|---|---|---|
| 1. Open Heart Pendant Size and Chain Gauge | ★★★★★ | An oversized pendant on a chunky oval-link chain is a decisive outlier against ten independent authentic references. |
| 2. Teardrop Bypass Ring Symmetry and Finish | ★★★★★ | Mismatched terminal drops and a patchier finish are real but confirmed on only one fake-vs-authentic pairing so far. |
| 4. Hallmark Wording and Placement | ★★★★★ | Correctly formatted on confirmed counterfeits across every named design — never a standalone confirmation. |
| 5. The "Made in Spain" Origin Stamp | ★★★★★ | A legitimate, confirmed manufacturing origin for this line — never flag it alone. |
| 3. Bean: What We Checked and What We Didn't Find | ★★★★★ | Both confirmed counterfeits checked directly show no repeatable construction difference from genuine pieces yet. |

Check My Hallmarks →Model Reference Before You Start
Elsa Peretti spans far more than three designs, and knowing which one you're holding matters before you apply any check below.
- Open Heart — a simple open-outline heart pendant, sold in sterling silver, 18k gold, and gemstone versions, in named sizes from roughly 11mm up to 27mm (Tiffany's own largest named spec). By far the most resold and most counterfeited Peretti design.
- Bean — a smooth, kidney-bean-shaped pendant or bracelet charm, sold in silver, gold, and occasionally lacquer finishes (including a red lacquer "Bean Design" pendant). Second most common design, but far thinner on the counterfeit side.
- Teardrop — a broad naming umbrella covering pendants, earrings, and bangles built from a single rounded teardrop shape. Within it, the Teardrop Bypass Ring is a distinct wrap/bypass silhouette: two rounded teardrop terminals that overlap in a continuous curve around the finger, not a plain band. Don't confuse it with a different product sometimes also listed as "Elsa Peretti Teardrop Ring": a plain band ring with a separate, dangling teardrop charm. The two are not the same design and don't share a failure pattern.
- The wider Elsa Peretti collection also includes the Bone Cuff, Diamonds by the Yard, Full Heart, Snake, Mesh, Padova, Wave, and Thumbprint lines, plus one-off pieces like the Hibiscus Flower Cuff and Sevillana pendant. These show up regularly among authenticated genuine pieces but too rarely among confirmed counterfeits in what we've reviewed to support a dedicated check; treat the checks below as the collection's core, not an exhaustive list.
Every genuine Elsa Peretti piece is stamped, somewhere on the metal, "TIFFANY & CO." with a small "©" and Elsa Peretti's cursive signature, a "925" (sterling) or gold karat mark, and often a country stamp reading "SPAIN," the confirmed, legitimate manufacturing origin for the line. None of that, on its own, settles authenticity, which the checks below cover directly.
Open Heart Pendant Size and Chain Gauge
This is the decisive check for the collection's most-faked design, and it's the one a buyer can run from a listing photo alone, no loupe required. Every genuine Open Heart necklace we pulled for direct comparison (ten independent examples, spanning sterling and gold, several explicitly naming their size in the listing) pairs a modest pendant, in the roughly 11mm to 27mm range Tiffany actually names, with a fine cable or rolo link chain: thin, uniform, oval links.
A counterfeit Open Heart necklace we examined pairs a heart photographed directly against a US quarter, reading close to or at the coin's diameter (at or beyond Tiffany's largest named size, roughly 25-27mm) and noticeably thicker in cross-section, with an unmistakably chunky oval-link chain closer in scale to a bracelet chain than anything seen on a genuine Open Heart necklace. The chain is the more immediately obvious tell of the two; the pendant's size sits at the very top edge of Tiffany's own range rather than clearly beyond it, so weigh it alongside the chain rather than on its own.
| Element | Authentic | Counterfeit |
|---|---|---|
| Pendant size | Modest, in Tiffany's named range (roughly 11mm-27mm); smaller than or close to a US quarter's diameter | At or beyond a quarter's diameter, at the very top edge of Tiffany's range or beyond it |
| Pendant thickness | Slim, consistent cross-section matching the named size | Noticeably thicker and heavier-looking metal than any genuine size |
| Chain | Fine cable or rolo link, thin uniform ovals | Chunky oval cable-link chain, individual links large and flattened |
Red flag
An Open Heart pendant that reads noticeably larger than a US quarter, or that hangs from a heavy oval-link chain rather than a fine cable chain, does not match any size or chain style Tiffany has produced for this design. This alone is enough to reject the piece.
Teardrop Bypass Ring Symmetry and Finish
Genuine Teardrop Bypass Rings show a smooth, continuous double curve: two terminal drops of matching size and weight, wrapping evenly around the finger with symmetric spacing between the two ends, finished to Tiffany's mirror-polish standard, one continuous highlight band runs along the curve in a good photo, rather than breaking up.
A counterfeit example we examined diverges on both points. The two terminal drops are visibly different sizes, one fuller and rounder, the other more tapered, and the wrap sits unevenly, pinched at the overlap rather than a smooth continuous curve. The surface finish is patchier too: visible fine tool marks concentrated at the bend, with reflections breaking up into scattered highlights instead of one continuous band.
| Element | Authentic | Counterfeit |
|---|---|---|
| Terminal drops | Matched size and weight on both ends | Visibly different sizes, one fuller, one more tapered |
| Wrap | Smooth, continuous curve, symmetric spacing | Pinched or uneven at the overlap |
| Surface finish | Even mirror polish, one continuous highlight band | Patchy polish, tool marks at the bend, broken-up reflections |
Worth knowing
We've verified this against one confirmed counterfeit and the single matching authentic Teardrop Bypass Ring in our reference set, since it's the only example of that exact silhouette we could locate on the authentic side. The difference is real and visible on direct comparison, but treat it as a supporting check rather than a standalone verdict given how thin that sample is. A plain "Teardrop Ring" with a separate dangling charm is a different product entirely and isn't covered by this check.
Bean: What We Checked and What We Didn't Find
Bean has real resale volume (dozens of genuine sterling, gold, and lacquer examples circulate), but only a couple of confirmed counterfeits, and neither shows the kind of construction gap the Open Heart or Teardrop fakes do. Both counterfeit Bean necklaces we examined carry a plausible bean silhouette, a fine cable chain proportioned like genuine examples, and a correctly formatted "TIFFANY & CO. © Elsa Peretti 925" hallmark, engraving depth and placement close enough to genuine that it isn't a usable tell on the pieces we reviewed.
That's worth stating plainly rather than papering over: on the small sample available, Bean doesn't currently support a dedicated red-flag checkpoint the way Open Heart does. Treat the design reference above (smooth, kidney-bean-shaped silhouette, fine cable chain, consistent hallmark placement) as what to expect, and lean on the Open Heart and Teardrop checks plus a professional opinion if a Bean piece looks otherwise inconsistent.
Worth knowing
We checked both confirmed Bean counterfeits in our archive directly against genuine reference pieces before writing this section, specifically to avoid asserting a tell that isn't there. Neither showed a repeatable difference, so this stays descriptive rather than a checkpoint row. We don't have a clean, publishable photo of either confirmed-fake Bean piece to show here, so we're not including one rather than substitute an unrelated image.
Hallmark Wording and Placement
Every genuine Open Heart, Bean, and Teardrop piece we've examined carries some version of "TIFFANY & CO." with a small "©" and Elsa Peretti's cursive signature, a "925" sterling mark (or the appropriate gold karat stamp), placed on the piece's flattest interior facet, plus, on necklaces, a separate small tag near the clasp reading "TIFFANY & CO." on one side and "SPAIN" on the other.
The problem is that this hallmark does not separate genuine pieces from fakes in what we've reviewed. Every counterfeit examined for this guide, across all three named designs, carries a correctly formatted, plausibly placed version of the same stamp. One platinum-band counterfeit we've seen presented in an apparently genuine Tiffany box and ribbon had crisp, well-formed engraving with no visible defect at all. A clean hallmark is necessary but nowhere near sufficient.
Worth knowing
A correctly worded, well-placed "TIFFANY & CO. © Elsa Peretti" hallmark does not confirm a piece is genuine. We've found it reproduced convincingly on confirmed counterfeits across every named design in this guide. Use it to rule out an obviously wrong stamp, then move to the proportion and finish checks above.
The "Made in Spain" Origin Stamp
Spain is a legitimate, confirmed manufacturing origin for Elsa Peretti pieces, found on numerous authenticated examples across Open Heart, Bean, and Teardrop designs alike. Some buyers treat any non-US origin stamp on a Tiffany piece as automatically suspicious; for this specific line, that instinct is simply wrong.
Worth knowing
Do not flag a "SPAIN" stamp on an Elsa Peretti piece as suspicious by itself. It's a normal, well-documented origin for this collection, not a counterfeit indicator.
What the Box and Pouch Do and Do Not Prove
Genuine Tiffany packaging (the signature Tiffany Blue box, felt pouch, and ribbon) is easy to source separately from eBay and resale sites, so a correct box proves nothing about what's inside it, and a missing or generic box doesn't make a genuine piece fake either. Use packaging only to cross-reference details like a printed style number or included paperwork against the piece itself, never as evidence on its own.
Quick Authentication Checklist
- Identify which design you're holding: Open Heart, Bean, or Teardrop Bypass Ring, since the checks differ.
- On an Open Heart necklace, compare the pendant to a US quarter, and check the chain is a fine cable link, not a chunky oval chain.
- On a Teardrop Bypass Ring, check the two terminal drops are matched in size and the wrap is a smooth, continuous curve, not pinched or uneven.
- On a Bean piece, confirm the silhouette and chain are plausible, but don't expect a construction tell on the small sample available; lean on a professional opinion if anything else looks off.
- Read the hallmark for correct wording and placement, but treat it as a baseline check only, not a verdict.
- Don't flag a "SPAIN" origin stamp as suspicious on its own.
- Treat the box and pouch as context only.
Two or more failures means walk away. A pendant-and-chain mismatch on an Open Heart necklace is, on its own, sufficient to reject the piece.
When to Get a Professional Opinion
The Open Heart proportion check catches the clearest fakes outright, an oversized pendant on a heavy chain simply isn't something Tiffany has produced. The harder cases are well-made Bean and Teardrop pieces that get the hallmark, chain gauge, and silhouette close enough that the difference, where one exists at all, comes down to fine casting and finish details that are easy to miss in a marketplace photo.
If you're buying an Elsa Peretti piece from a private sale or resale marketplace with no original receipt, get a second opinion before paying. LuxeDetect authenticates Tiffany & Co. jewelry from $30 with a verdict and Certificate of Authenticity within 24 hours. Send clear photos of the hallmark, the chain links close up, and, for an Open Heart piece, a shot of the pendant next to a coin for scale.
FAQ
What's the fastest way to check an Elsa Peretti Open Heart necklace?
Photograph the pendant next to a US quarter and look at the chain first. Genuine Open Heart necklaces use a fine cable or rolo chain regardless of pendant size; a chunky oval-link chain closer in scale to a bracelet is the clearest single tell. Pendant size is a secondary check: genuine pendants stay at or under roughly 27mm, Tiffany's largest named size, so a heart that reads clearly beyond the quarter's diameter, especially paired with that heavier chain, is a strong sign of a non-Tiffany or counterfeit piece.
Does a correct Tiffany hallmark prove an Elsa Peretti piece is real?
No. We've found the "TIFFANY & CO. © Elsa Peretti 925" hallmark reproduced convincingly, correct wording, plausible placement, on confirmed counterfeits across Open Heart, Bean, and Teardrop pieces alike. Use it to catch an obviously wrong stamp, then check proportion and finish, not the other way around.
Is a "Made in Spain" stamp a red flag on Tiffany jewelry?
Not for Elsa Peretti. Spain is a legitimate, well-documented manufacturing origin for this specific collection, confirmed across many authenticated pieces. Don't treat a country stamp alone as suspicious; check the piece's construction instead.
What's the difference between a Teardrop Bypass Ring and an Elsa Peretti Teardrop Ring?
They're different products despite similar names. The Teardrop Bypass Ring is a wrap design: two rounded teardrop terminals that overlap in a continuous curve around the finger. A separately listed "Elsa Peretti Teardrop Ring" can instead be a plain band with a single dangling teardrop charm, a different silhouette entirely. Confirm which one you're looking at before applying the symmetry and finish check.
Why doesn't this guide cover Bone Cuff or Diamonds by the Yard as their own checks?
Both show up regularly among genuine Elsa Peretti pieces we've reviewed but too rarely among confirmed counterfeits to support a dedicated checkpoint. This guide covers the three designs, Open Heart, Bean, and Teardrop, where we have enough confirmed fake examples to describe a repeatable pattern; the rest of the collection is genuine, well-documented territory, just not (yet) a common counterfeit target in what we've seen.
Are Elsa Peretti pieces always stamped 925 for sterling silver?
Sterling silver pieces are stamped "925." Gold pieces carry the matching karat stamp instead (750 for 18k, for example), and weigh more than an equivalent silver piece of the same design. The proportion and finish checks in this guide apply the same way regardless of metal.
Is the Elsa Peretti Bean design commonly faked?
Less than Open Heart. Bean has meaningful resale volume, but confirmed counterfeits are a small fraction of what we see for Open Heart, and the ones we've examined directly don't show a repeatable construction difference from genuine pieces. Treat an unusual Bean listing with the same general caution as any resale luxury purchase, and get a professional opinion if anything about the piece looks inconsistent.
