Motley x Alessandro Petrolati - Onyx and Mother of Pearl Ada Ring

Oh, the perfection of circles. New to Alessandro Petrolati’s Geometry ring series, it's the Yin Yang two-tone hues of onyx and mother of pearl that captured our hearts. Check out its four silver feet - when you're not wearing it, use it as a freestanding mini sculpture. Also available in onyx and malachite, quartz and mother of pearl, blue agate and onyx, red and pink agate. Every piece of Motley jewellery comes beautifully packaged and gift-ready, with its own free travel pouch and polishing cloth (whether that gift's for someone else, or for you).

• 925 sterling silver

Fed up with settling for good-looking jewellery that would eventually break, friends Cecily and Ilana set up MOTLEY with one mission: to make the best design accessible to everyone. Every collection is created in collaboration with a top designer and crafted using the materials and techniques used in fine jewellery.
