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.

Vitreous iolite stones appear in deep blue shades, enrapturing admirers with their strong pleochroism, an optical phenomenon that makes the gemstone appear to have different colours when observed from different angles. With these strong polarising effects at varying angles, it's said vikings harnessed the stones' powers to determine the position of the sun on overcast days.
