The Tiffany&Company Starfish Necklace is a luxurious and reasonably affordable piece from the legendary jeweler. Predictably, it has therefore been copied left and right, and sub-par knock-offs have flooded the market. If you're shopping for this piece, it's important to know what you're paying for; if it's not Tiffany, it's not worth it. Make sure you watch out for these telltale signs when purchasing this necklace from anywhere other than a Tiffany store.
Never buy a Tiffany item on sale; this company does not have closeouts, outlets or anything of the sort. If you find a Starfish necklace for less than $375, it is either damaged or not a real Tiffany.
Look for seams on the links of the chain. The links on a Tiffany chain are soldered together, so it's virtually impossible to see the seam. If the chain on your necklace looks as if the links have been pinched together, it's very likely a fake.
Look for the number 925 stamped at the base of the clasp and on the pendant itself. Real Tiffany pieces always have this, and a clasp or pendant lacking this mark is a sure-fire sign of a fake.
Lift the necklace to get a feel for its weight. A real Tiffany necklace is heavy. Tiffany uses .925 sterling silver, and it feels dense and weighty. If your necklace feels flimsy and light, it's a fake.
Look for a seam on the pendant. Like the chain links, the pendant on a real Tiffany necklace is soldered and looks nearly seamless; the front and back look at first glance like one solid piece. If there is an obvious seam between the front of the pendant and the back, it's a fake.
