Also known as potentilla, these little five-petal flowers are certainly common enough, but still uncommonly sweet. I had them on my mind this second spring of Covid lockdown -- eager for winter and the pandemic to be over! -- and these are the result. Small studs, diameter about 8 mm, making them a perfect leave-in-always earrings. Available in all four Disegno colours of 18k gold: yellow, rose, green and (shown here) white.
