My Finita claw set stud earring design is a simplicity itself, and this pretty, open setting lets the light pour in to the stones making them sparkle all day. And like my Theresa studs, they are part of my interchangeable collection of earrings, becoming the centre of attention in my halos: purple amethyst Finita's sparkle even more with a Cactus diamond halo, and green chrome diopside Finita's feel uplifted with the gold Shippo halo.

Taken from the Greek word "amethystos", meaning sober; amethyst quartz has illustrious calming properties, protecting wearers with a sense of tranquillity and soberness. Famed for its regal deep purple colour, February's birthstone is said to enhance your focus and open your mind to critical thinking and clarity, and to also protect from inebriation. It is often worn by bishops set in a ring. Most are sourced from alluvial deposits in Brazil, Madagascar, Zambia and Uruguay, and Cassandra likes to juxtapose their splendour with rubies and aquamarine, or even green African garnets.
