Horn is a really interesting jewellery material – it’s light, malleable, and lends itself to a lot of designs. Case in point: this bracelet by Ashley Pittman, set with emerald, sapphire, pink tourmaline, amethyst, turquoise, and ruby in brass bezels. This collection uses natural horn carved by a women’s cooperative, fair-trade semi-precious gemstones, bronze and other materials indigenous to East Africa.

It’s available from Bergdorf Goodman and also comes in dark horn and different widths. This one sells for USD $1,350.
