Jewelry Design Irises Ring by Larissa Moraes Irises is a double ring inspired by a painting by Vincent van Gogh. The painting shows blue flowers with long, sword shaped leaves. In the ring, the flowers are represented by blue sapphire and by London and sky topaz, while sculptured gold forms the leaves in movement. The ring is made of 18 karat gold by hand, with a matte finish and prong settings. The piece is light and comfortable to wear. The intent is to bring the colors and forms of nature and painting into a wearable object.
