T Smile Pendant: real vs fake
The T Smile Pendant is a minimal "smile" arc where everything rides on the smoothness of the curve and even metal thickness along its length. Replicas give it away with a crooked, wobbly bend or crude engraving on the back. LegitCheck AI checks the arc, hallmarks and polish from your photos.
What to check on the T Smile Pendant
Model-specific zones – on top of the brand-level signs.
The "smile" arc
The authentic arc is smooth and symmetrical, thickening evenly toward the center with matching curled tips. Sharp kinks in the line, asymmetry, or a wobbly curve give away a replica.
Engraving and metal mark
The back carries the brand hallmark and the purity mark in a clean, even font: look for crisp edges and consistent depth on the characters. Hallmark variants depend on the era and the line: "TIFFANY & CO." or the shortened "T&CO.", for gold "750", "AU750" or "Tiffany & Co. 750", for silver "925", and on vintage pieces "STERLING" or "925-1000"; designer lines add a signature (Elsa Peretti, Paloma Picasso) and a country (Spain, for example). Judge the cleanliness and depth of the strike, not conformity to a single template.
Even thickness along the length
The metal changes cross-section smoothly and symmetrically; abrupt steps, stamping marks, or uneven facets are not typical of the original.
Bail and hang
The chain loop is neatly soldered with no visible seam or excess solder, and a clean opening. A rough or skewed bail is a warning sign.
Surface polish
The mirror surface is even, with no waviness or dull zones, and the shine is consistent across the whole arc. Patchy or plasticky polish shows up on fakes.

FAQ
How smooth should the pendant arc be?
The curve should read as smooth and symmetrical, with no kinks or sags. Any "wobble" in the line or a lopsided arc on a macro photo is reason to look closer.
There is no hallmark on the back – does that make it fake?
The original carries the brand hallmark – the full "TIFFANY & CO." or the shortened "T&CO." – and a metal mark in one of the accepted variants ("750", "AU750", "925", or "STERLING" on vintage). A total absence of hallmarks is suspicious, but do not conclude from one sign – weigh the shape, engraving and polish together.
