Tiffany 1837 Collection Authentication Guide: What Genuine Looks Like (2026)

Why the Tiffany 1837 Collection Is Hard to Judge From Stamps

The 1837 collection is named for the year Tiffany was founded, and almost every piece in it is built around the same design idea: a plain concave silver surface carrying three small marks in a row. A hexagonal cartouche holds the metal mark (925 on silver), the middle carries "T&CO", and a rounded cartouche holds "1837". The same row appears on the narrow and wide band rings, the bangles and cuffs, the circle and interlocking-circle pendants, the padlock and the disc link bracelets. That consistency is what makes the line popular, and it is also what makes it easy to copy: there are only a few marks to get right, and they are on the outside of the piece where any photo shows them.

This guide is different from our other Tiffany guides. The general Tiffany jewelry guide covers chain, clasp and the Return to Tiffany tag, the Return to Tiffany guide covers that tag in depth, and the Elsa Peretti guide covers the Peretti line. Here we look only at the 1837 stamp system, because it is where most buyers start and where the usual advice goes wrong.

The Exterior Stamp Row

On the genuine band rings, bangles and cuffs we reviewed, the outside carries three marks in a line: a hexagonal cartouche with the metal mark, "T&CO" in a heavy serif face, and a rounded cartouche with "1837".

Two points are worth knowing before you judge a photo. First, the genuine "1837" cartouche has a doubled outline, as the photo above shows, so a double border is not a sign of a copy. Second, the corners and proportions of the cartouches vary between genuine pieces and sizes: we saw rounded, clipped and chamfered versions on authenticated rings and bangles, so shape on its own is a weak check.

The Interior Mark

Inside the rings we reviewed, a line of small text runs around the band. On the genuine rings it reads "©1997 TIFFANY & Co. 925", with the copyright sign and year first and the metal mark last.

The spacing of this line is not fixed. Some genuine bangles carry a version without a year and with the letters set tight, reading "©TIFFANY&Co. 925".

Circle, Interlocking and Disc Pieces

The pendants and link bracelets spread the same three marks around the piece rather than in one row. On the genuine circle pendant the marks sit on the rim and the inside face carries the interior line.

Chain and clasp work on these pendants follows the same rules as other Tiffany necklaces, so check them with the general guide. Tags on genuine chains we reviewed read variously "AG925" or "©TIFFANY&Co.", so one tag style is not a rule.

What We Found on Fake-Labelled 1837 Pieces

We went through a wide sample of fake-labelled 1837 orders: rings, bangles, cuffs, circle and square pendants, a padlock, earrings and bracelets. The honest summary:

• Most reproduced the stamps well. Many carried the hexagonal 925 cartouche, the rounded 1837 cartouche, "T&CO" and an interior line that looks right in a normal photo. On several, the stamp set would pass a casual comparison with the genuine photos above.
• Spacing did not separate them. Tight interior lettering appeared on both fake-labelled and genuine pieces.

Because the best copies get the marks right, a correct stamp set is a reason to keep looking, not a reason to relax. We found no repeatable stamp tell we would stand behind.

What to Rely On, and What Not To

• Rely on: a full match to the stamp row and interior line shown above, consistent crisp strike depth across all marks, a solid dense feel for the size, and clear close photos or in-person inspection from the seller.
• Do not rely on: stamp spacing alone, the double border on the 1837 cartouche (genuine pieces have it), a correct set of marks by themselves, or the box and pouch. Packaging is context, never evidence.
• Malformed lettering or a mismatched metal mark is worth a closer look. The reverse is not true: a clean surface and a correct stamp set do not clear a piece.

When to Get a Professional Opinion

A band ring or bangle in this line can be worth a few hundred dollars on resale, and the marks alone cannot settle it. If the piece matches everything here and the price is significant, a professional check of close photos is the reliable next step. Our authentication service looks at the stamp row, interior mark, strike depth and construction, and returns a verdict with a Certificate of Authenticity.
