How to Authenticate Tiffany & Co
Tiffany & Co. Markings
Authentic Tiffany pieces are stamped with "Tiffany & Co." followed by metal purity marks like "925" for sterling silver or "750" for 18k gold, plus the designer's name for signed collections like Elsa Peretti or Paloma Picasso. The stamping should be crisp, evenly spaced, and precisely executed—never fuzzy or unevenly deep. Post-1965 sterling pieces also include a numeric or alphanumeric code indicating production date and location.
Return to Tiffany Engravings
The iconic "Return to Tiffany" collection features the phrase "Please Return to Tiffany & Co. New York" engraved on heart tags and key rings with exceptionally uniform depth and spacing. Authentic pieces show consistent letter height and professionally executed serifs on the font. Counterfeits typically display irregular spacing, varying letter depths, or font inconsistencies that differ from Tiffany's precise engraving standards.
Tiffany Blue Box Packaging
Genuine Tiffany packaging uses their proprietary Pantone 1837 Blue (named after their founding year) with a specific robin's egg blue shade that cannot be legally reproduced by other companies. The box should have a white satin ribbon with clean edges, crisp corners on the box construction, and embossed lettering on the inside lid. The blue color should be consistent across all packaging elements without variation in shade or tone.
Atlas Collection Numerals
The Atlas collection features Roman numerals inspired by the clock above Tiffany's Fifth Avenue flagship store, and authentic pieces display perfectly proportioned, deeply engraved numerals with consistent spacing and depth. Each numeral should be aligned precisely with geometric accuracy, showing Tiffany's expert craftsmanship. Counterfeit Atlas pieces often have uneven numeral spacing, shallow engravings, or incorrect Roman numeral proportions that deviate from the original architectural inspiration.
Tiffany Setting Diamond Prongs
The legendary Tiffany Setting engagement ring, introduced in 1886, features six platinum or gold prongs that hold the diamond high above the band to maximize light exposure and brilliance. Authentic Tiffany Settings show impeccably smooth, symmetrical prongs of uniform thickness with knife-edge precision where they meet the diamond. Each ring includes a unique serial number engraved inside the band along with metal content marks and the Tiffany & Co. signature stamp.
Common Red Flags
- Counterfeit Tiffany pieces often misspell the stamp as "Tiffany & Co" without the period after "Co" or use "Tiffany Co." without the ampersand, which never appears on authentic pieces.
- Fake Return to Tiffany heart tags frequently display the phrase "Please Return to Tiffany New York" omitting the "& Co." portion, which is always included on genuine pieces.
- Counterfeiters cannot legally reproduce Pantone 1837 Blue, so fake Tiffany boxes appear in incorrect shades ranging from turquoise to sky blue instead of the precise robin's egg blue tone.
- Fake Tiffany jewelry often shows poorly executed or missing metal purity marks (925, 750, PT950) alongside the Tiffany stamp, or displays stamps in incorrect locations where authentic pieces would never be marked.
- Counterfeit Tiffany T collection and Tiffany HardWear pieces display rough, unpolished edges and asymmetrical shapes, whereas authentic pieces feature perfectly smooth transitions, mirror-polished surfaces, and mathematically precise geometric proportions.
