Not Kidding, Lady Gaga's Diamond Necklace Took Over 365 Days to Make

There are a lot of reasons to buzz about Lady Gaga's shimmering look this evening at the Grammy Awards. For starters, the singer-slash-actress stepped out in a metallic silver dress by the recently re-vamped Celine—an '80s-inspired strapless number with a large asymmetric ruffle. But everything else about her look shimmered, too, from her silvery tresses and metallic shoes to the diamond necklace that's about to make your jaw drop.

Gaga accessorized her Grammy Awards look with a Tiffany & Co. diamond necklace that apparently took over a year to make, according to the jewelry brand. The necklace, which has over 91 carats of diamonds, features "an ice motif that required the most skilled craftsman and harnessed technique to accomplish," says the brand. Has your jaw dropped yet?
