What’s Snaky, Easy to Wear and Scaled With Diamonds?

While the haute jewelry world continues to revel in chunky collars adorned with oversize gems, Tiffany & Company’s design director, Francesca Amfitheatrof, has instead gone for a radically casual take on the oft-interpreted diamond-encrusted necklace. Evoking a snaky, sinuous form, this 27-inch piece swings insouciantly against the body, accommodating itself to the wearer’s mobility rather than limiting it. Crafted from more than 100 carats of marquise-cut diamonds in subtly graduating sizes and affixed to an almost-invisible platinum armature, it’s the ultimate in throw-it-on luxury.
