Tiffany & Co. Authentication Guide
America's most iconic jewelry house—what collectors need to know.
Last updated: January 28, 2026
Tiffany & Co. Authentication Guide
Tiffany & Co. is America's most famous jewelry house. Since 1837, they've set standards for quality and design. The robin's egg blue box is globally recognized—which makes Tiffany one of the most counterfeited brands.
Here's what actually matters for authentication.
Tiffany History: The American Icon
1837: Charles Lewis Tiffany opens a stationery and fancy goods store in New York City.
1853: Tiffany takes over and renames the company Tiffany & Co.
1878: Acquires the Tiffany Diamond (128.54 carats, yellow diamond).
1886: Introduces the Tiffany Setting (six-prong diamond engagement ring).
1950s-1980s: Designs from Schlumberger, Peretti, Picasso establish modern identity.
2021: LVMH acquires Tiffany.
Today: Global luxury house known for silver, engagement rings, and designer collaborations.
What Makes Tiffany Different
Sterling silver heritage. Unlike European houses that focus on gold, Tiffany is famous for sterling silver pieces.
Designer collaborations. Elsa Peretti, Paloma Picasso, and Jean Schlumberger pieces carry additional signatures.
American hallmarking. US doesn't have independent assay offices like the UK or France. Tiffany's marks are their own.
Wide price range. From $150 silver pieces to $1,000,000+ high jewelry.

- Chain links near closure
Necklaces:
- Clasp tag

Tiffany Metal Marks
Understanding gold hallmarks by country and platinum hallmarks helps when evaluating Tiffany's international pieces.
Sterling Silver (Primary)
- "925" or "STERLING"
- Most common for Tiffany
- Should feel substantial
18K Gold
- "750" or "18K"
- Used for fine jewelry
- Expect quality finishing
Platinum
- "PLAT" or "PT950"
- Fine pieces and engagement rings
Important: Tiffany doesn't commonly use 14K gold. If you see 14K on a Tiffany piece, investigate carefully—some international pieces exist, but it's unusual.
The Box and Packaging Question
Tiffany's blue box is famous. It's also meaningless for authentication.
Reality:
- Boxes can be purchased separately
- Fakes come in authentic-looking boxes
- Vintage boxes don't prove vintage pieces
The rule: The jewelry itself must authenticate independently. The box is nice to have, not proof.
Tiffany Construction Quality
What to expect:
Sterling silver:
- Substantial weight
- Quality finishing
- Smooth solder joints
- Working mechanisms
Gold and platinum:
- Appropriate heft
- Clean construction
- Quality stone settings
- Era-appropriate design
All pieces:
- Clear, crisp engraving
- Consistent quality throughout
- No rough edges or poor finishing
Red Flags for Tiffany

- Missing metal marks (925, 750)
- Poor engraving quality
- Modern marks on "vintage" pieces
- Wrong signature format for era
Construction issues:
- Lightweight silver
- Poor chain quality
- Rough finishing
- Weak clasps
Design issues:
- Proportions that don't match authentic examples

Frequently Asked Questions
Is my Tiffany real? Check marks, construction quality, and design accuracy. Multiple factors together tell the story.
Will Tiffany authenticate my piece? Sometimes. Boutiques may verify pieces, especially for service purposes. Results vary.
Can I verify a serial number? Not all Tiffany pieces have serial numbers. Where present, they provide one data point—not proof.
Is vintage Tiffany valuable? Yes, especially pieces from named designers (Peretti, Picasso, Schlumberger) and antique items with provenance.
What's the difference between "Tiffany style" and "signed Tiffany"? "Tiffany style" means looks similar but isn't Tiffany. Only pieces with "TIFFANY & CO." signature are genuine Tiffany.
Are Tiffany fakes common? Yes, especially Return to Tiffany pieces (accessible price point + recognition = heavy counterfeiting).
