Deep green is the colour that makes silver look expensive and gold look antique. This one is a rich emerald-toned cubic zirconia, round and faceted, held low in a smooth bezel with the metal wrapped completely around it. The darker the stone, the more the setting matters — a closed bezel gives the green a solid edge to sit against, so it reads as depth rather than as a dark spot. Each earring is 925 sterling silver with a slim post and butterfly back, in the smaller of our two sizes.

Green sits beautifully against auburn and dark hair, and it is the one colour here that carries into evening without any effort. Wear the pair for something quiet and grown-up, or use one as the deepest note in a stacked ear. Available in gold, rose gold and silver. Hypoallergenic sterling silver keeps them kind to sensitive lobes, and the small size means they stay comfortable under a pair of headphones or a phone held to your ear.
