How to Tell if Tiffany Jewellery Is Real

Look for a clean Tiffany & Co. or T&Co. stamp with the metal mark: 925 on sterling silver, 750 on 18KT gold, a platinum mark such as PT950. Designer pieces add the designer's name. The stamps should be crisp, straight and correctly spelt, the piece should feel solid, and clasps should be well made and stamped too.

925 means sterling silver: 925 parts in 1,000 are pure silver, or 92.5%. Most Tiffany silver is stamped Tiffany & Co. with 925, often also AG 925 or STERLING on older pieces. The mark tells you the metal, not that the piece is genuine Tiffany, because copies are stamped 925 as well.

Read the engraving: genuine tags say Please Return to Tiffany & Co. New York, evenly spaced and cleanly cut, with 925 or a gold mark on the tag and a stamp on the clasp. Fakes often have shallow, crooked or wrongly spaced letters, a light tag, rough edges and an unstamped or flimsy clasp.

Yes. Elsa Peretti pieces are stamped with her name and Tiffany & Co., and Paloma Picasso pieces with her name and Tiffany & Co., each with a metal mark such as 925 or 750. Peretti designed for Tiffany from 1974 and Picasso from 1980. A missing signature or a misspelt one is a warning sign.

No. The blue box, pouch, bag and receipt support a genuine piece, but genuine packaging is sold on its own and copied too, so it can come with the wrong item. Many genuine Tiffany pieces have lost their packaging. The marks, weight and workmanship of the piece itself decide.

Vintage Tiffany is usually signed Tiffany & Co. with the metal stamped separately, such as 14K, 18K, STERLING or PLAT on American pieces. Designer pieces from the 1950s onwards add names such as Schlumberger, Peretti, Picasso or Cummings. Older pieces may show wear to the stamps, which is normal.

Shallow, uneven or misspelt stamps, Tiffany written in the wrong typeface, a piece that feels light, plating wearing to a different colour, rough edges and seams, flimsy unstamped clasps, and a 925 mark on a piece sold as gold. Any one of these calls for a closer check by a specialist before buying or selling.

Yes. Send clear photographs of the whole piece, the Tiffany stamp, the metal mark, the clasp and any box, pouch or receipt. We check them against the design, tell you what we see and give a free valuation within one working day. Mozeris is an independent dealer, not a Tiffany store or agent.

Look inside the band for a clean Tiffany & Co. or T&Co. stamp with 925, 750 or a platinum mark, and on designer rings the designer's name. On an 1837 ring the date is part of the design on the outside and must be sharp and evenly spaced. Heart rings should have smooth, even edges and no plating wear.

Check the stamp on the tag or pendant and on the clasp: both should be crisp and correctly spelt, with 925 or 750. On a toggle necklace the bar and the ring are usually both stamped. Links should be even and solid, and the piece should hang and move smoothly, without rough joins.

Yes. Tiffany & Co. sets its fine jewellery with real diamonds, and its engagement rings carry a serial number engraved on the band. A genuine Tiffany diamond tests as diamond, and larger stones usually come with documentation. A stone that tests as cubic zirconia or moissanite rules out a genuine Tiffany diamond piece.

Check the pearls and the metal. Real pearls feel slightly gritty when rubbed gently against a tooth, while imitations feel smooth. The clasp or setting should carry a clean Tiffany & Co. stamp and a metal mark such as 750 or 925. Knotted strands should have a knot between each pearl.

New men's Tiffany jewellery is sold by Tiffany & Co. stores and its website. Pre-owned pieces are sold by specialist dealers and auction houses, who should check the stamps and metal before selling. We sell pre-owned Tiffany when it is in stock, each piece checked; we are not affiliated with Tiffany & Co.

Genuine Tiffany boxes, pouches and bags come with purchases, and many empty ones are resold. Because they can be paired with copies, packaging on its own never proves a piece is real. Antique and vintage Tiffany & Co. leather boxes are collected in their own right.

Yes. Tiffany Blue was registered as a trademark in 1998, and in 2001 Tiffany worked with Pantone to standardise the shade as 1837 Blue, after the year the company was founded. Tiffany also published its Blue Book catalogue from 1845, and the blue box is known worldwide.

No. Tiffany leaded glass lamps were made by Tiffany Studios, the firm of Louis Comfort Tiffany, son of Tiffany & Co.'s founder Charles Lewis Tiffany. Tiffany Studios also made bronze desk objects. Lamps sold as Tiffany style are made by other firms in the same manner and are not Tiffany Studios pieces.

The same rules apply as for jewellery. Look for a crisp Tiffany & Co. stamp with 925 or STERLING, even engraving, solid weight and smooth edges. Copies of small silver gifts are common, so check the stamp under magnification and compare it with a known genuine piece.
