Cloud Ring by Bibi van der Velden

The intriguing design of this ring by Bibi Van der Velden, with its highly ingenious contrasts of shape and texture, would seem alone enough to render it deserving of the shapeliest of fingers. But it has a rather unusual and exciting extra twist. For the ring’s ultra-modern, cumulonimbine undulations are not moulded from some state-of-the-art composite but carved from the tusks of a beast that lived as much as four and a half million years ago – mammoth ivory discovered by Bibi herself on a trip to the frozen wastes of Siberia. Quite a story to wear on your finger, this remarkable piece has been created exclusively for 20ltd.com and is available in only 10 editions.
