How to Tell if Stone Island Is Real: Badge, Certilogo, Labels

A genuine Stone Island badge can sit on a fake garment, because it buttons off. The Certilogo code, the back of the badge, the art number and the garment itself tell.

Updated November 2, 2026

To tell if Stone Island is real, check the Certilogo code first: every garment since spring/summer 2014 carries a 12-digit CLG code and QR on an inner label, which you verify at certilogo.com. Then check the compass badge, especially its back, and the art number on the inner label. As of November 2026, genuine used sweatshirts sell for about $70 to $165 and jackets for about $100 to $350.

The badge alone does not settle it. It buttons on so it can come off for washing, which means genuine badges end up on fake garments. The code, the labels and the garment have to agree with it.

Quick answer

  • Since SS2014: a 12-digit Certilogo (CLG) code with a QR code on an inner label. Verify it on certilogo.com or by scanning the QR, and answer the questions honestly.
  • Badge front: pale, matte green and yellow, a drop stitch around the compass, crisp lettering. Badge back: irregular black areas and little white; fakes look neat and blocky.
  • Art number: on the inner label; the first digits give the season, and it should search to your exact garment type.
  • Used values: sweatshirts about $70-165, jackets about $100-350. Retail is roughly $300-450 for a sweatshirt.
  • Fakes copy the badge front, the badge itself (real badges get moved onto fakes) and printed Certilogo labels. Pre-2014 pieces have no code: eBay's Authenticity Guarantee (no fee on eligible streetwear) or Legit App (from $4) are the next step.

Which tells actually separate real Stone Island from fake?

  1. The Certilogo code (2014 onward). From spring/summer 2014, every garment has an inner label with a 12-digit CLG code and a QR code. Scan the QR or enter the code at certilogo.com, answer a few questions (store or online purchase, for example), and send label photos if asked. Copied codes are a known trick, so Certilogo flags a code checked many times in many places. If the result says not authentic, treat the garment as fake.
  2. The back of the badge. This is the most useful physical check on the badge. Flip it over. A genuine back shows irregular black areas and very little white, often with some yellow thread from the compass coming through; colour can vary slightly. Replicas tend to show large, neat black and white blocks and lettering that is too clearly defined from behind.
  3. The front of the badge. Genuine greens and yellows are pale and matte, not bright or shiny. There is a green or yellow drop stitch around the compass, and the compass points are stitched tightly into the center so the fabric gathers slightly inward. Replicas often use shinier, almost glittery thread, a greyer green, misshapen letters, and a compass that sits on the surface.
  4. The art number. Every garment carries an art (article) number on the inner label, a string of digits often printed in two groups, such as 6915 62138 on an AW18 piece. The first two digits give the season and year (69 is AW18, and the number rises by one each season), the next two the brand (15 for Stone Island), and the rest the product type and model. Search the number: a jacket number that returns an old T-shirt is a red flag. Truss Archive keeps an art number checker for this.
  5. The garment itself. Stone Island is known for garment dyeing, which leaves slight shading where seams pucker. Fabric weight, the hood shape and hardware should match retail photos of the same season. Thermochromic and reflective pieces should react the way the fabric is sold to: heat-reactive fabrics change colour evenly under a warm hand.

Check the badge from both sides, then the inner labels. Badges are detachable, so they never settle a garment on their own. Schematic, not to scale; label layouts vary by season.

What do fakes get right?

How to date a Stone Island piece

Stone Island was founded by Massimo Osti in 1982 in Ravarino, Italy, and its badge has changed in ways that help date a piece.

Period What to look for
1982 to about 1999 "Green edge" badge: green border, black stitching through the green and gold. Highly collectible. Early pieces may have the badge on the front rather than the arm.
About 2000 to 2013 Black-edged badge, the familiar modern look. No Certilogo label. Use the art number, labels and construction.
SS2014 onward Certilogo label with 12-digit CLG code and QR on all garments.
Since 2021 Owned by Moncler, which completed its purchase in March 2021.

Ghost pieces use a tonal, monochrome badge that matches the garment, and Shadow Project, the experimental line, uses its own badge. Neither is a sign of a fake. Pre-2014 pieces are where checks get harder, and where an experienced Stone Island dealer is worth consulting.

What is genuine Stone Island worth?

Rough used values as of November 2026, from Poshmark and Mercari sold results and the original retail prices recorded in those listings.

Item Retail new, roughly Used, good condition
Crewneck or hooded sweatshirt $300-450 About $70-165
Quarter-zip or nylon sweatshirt Roughly $400 and up About $80-190
Overshirt or lightweight jacket Varies About $90-200
Field jacket, parka or puffer Varies widely by fabric About $100-350
Green-edge badge pieces (to 1999) Not applicable Sales are thin; often more than modern pieces of the same type

Examples from Poshmark sold results: a Stone Island AW18 quarter-zip with art number 691562138 sold for $140, NWT grey sweatshirts for $144 and $150 (one listed at $340 original), a black puffer for $205 and a hooded field jacket for $200. Mercari sold results land in the same ranges: crewnecks and hoodies mostly $50 to $175, nylon and canvas overshirts around $185 to $215, and jackets, puffers and vests about $95 to $260. Quarter-zips sell less often; we found only two there, at $68 and $120. Fading on garment-dyed pieces, a missing badge or missing badge buttons all lower the price. A garment without its badge sells for much less, because buyers want the badge.

Say you find a Stone Island sweatshirt at a market

Say a market stall has a navy crewneck with a badge for $40. You scan the Certilogo QR inside, answer the questions, and the result is authentic. The art number searches to a crewneck from a recent autumn/winter season, and the badge back shows irregular dark areas with yellow thread. Clean, it should sell for roughly $70 to $165. If the code had failed, or the label were missing on a garment with a post-2014 art number, you would leave it, however good the badge looks.

Where to sell genuine Stone Island, and what not to do

Do not share the full Certilogo code in a public listing: a published genuine code can be copied onto fakes. Blur part of it and offer the full code to a serious buyer. Do not sell a garment without its badge as complete, and keep the badge buttons.

What settles it

Photos rule out the easy fakes: a bright glittery badge, a neat blocky badge back, an art number that returns a T-shirt for a jacket, and a post-2014 garment with no Certilogo label. What they cannot prove is that a garment which passes is genuine, because the badge buttons off and genuine badges are moved onto fakes, and replica labels print real-looking codes.

For anything from spring/summer 2014 onward, the step that settles it is Certilogo. Read the QR with a phone or enter the 12-digit CLG code at certilogo.com, answer the questions honestly and send label photos if asked; a result of not authentic settles it as a fake, and a code flagged as checked many times in many places is the mark of a copied code. Ask a private seller to run it in front of you before you pay.

For pre-2014 and green-edge pieces there is no code. Then the settling step is an in-hand look: eBay's Authenticity Guarantee inspects eligible streetwear at no fee within two business days of receipt, and a specialist Stone Island dealer who knows the archive is the right judge for a valuable older piece.

Common mistakes

The same check-the-garment logic applies to Moncler, which now owns Stone Island, and to other streetwear such as Supreme and Burberry.

How do you get Stone Island verified, and what does it cost?

Route Cost Works for What you get
Certilogo (certilogo.com or the QR) Nothing to pay SS2014 onward A yes or no tied to the code, after a few questions
eBay Authenticity Guarantee No fee for eligible streetwear Any era, select apparel in eBay's clothing categories In-hand inspection within two business days of receipt, a QR tag, refund on a fail
Legit App From $4 per item Any era, from photos A photo-based opinion
Specialist Stone Island dealer Usually part of a sale or consignment Pre-2014 and green-edge pieces An experienced in-hand opinion

For a post-2014 garment, Certilogo comes first and settles most cases. For older pieces, where there is no code, use eBay's inspection when buying and a specialist when the piece is valuable.

How WorthPic reads Stone Island photos

WorthPic runs on the newest and most capable AI model available, tuned for exactly this kind of identification. From clear photos it reads the inner labels and art number, notes whether a Certilogo label is present, identifies the garment and season where it can, and checks whether the badge front and back and the garment are consistent with genuine Stone Island of that period. It gives a resale range with a most likely figure and names the photo that would settle a doubt, usually the badge back or the inner label. It cannot run your Certilogo code for you or feel the fabric. WorthPic identifies and estimates. It does not authenticate, grade or appraise, and a photo check never proves a garment is genuine; for that, use Certilogo and, for older pieces, a specialist.

Questions people ask

How do I check a Stone Island Certilogo code?

Scan the QR on the label or enter the 12-digit CLG code at certilogo.com, then answer the questions. Do it before you pay: ask a private seller for a clear photo of the label, or to run the check in front of you.

Do all Stone Island garments have a Certilogo?

All garments from spring/summer 2014 onward should. Older pieces do not, so check the art number, the badge and the construction instead.

Can a real badge be on a fake Stone Island?

Yes. Genuine badges are sold on their own and buttoned onto fakes. A real badge on a post-2014 garment with no Certilogo label means the garment is not genuine.

What does the art number on Stone Island mean?

It identifies the season, the line and the model. The first two digits give the season and year, and the next two the brand (15 for Stone Island). Search it to confirm it matches your garment type.

Why does Certilogo say my code has been checked before?

Certilogo records how often and where a code is checked. One or two earlier checks are normal on a used garment, because the previous owner probably checked it. A code checked many times in many places is the pattern a copied code leaves, and Certilogo flags it. Answer its questions honestly and send the label photos it asks for.

Why is my Stone Island badge green-edged?

Green-edged badges were used until about 1999, when the black-edged badge took over. They mark an older piece, which collectors value, but they are also copied, so check the garment and labels carefully.
