David Hensel is a fascinating sculptor, painter and jewellery maker. He received some not altogether welcome publicity some years ago when the Royal Academy Summer Show exhibited a plinth without the sculpture that should have stood on  it. He has made a number of commissions for me and my family, but he is now concentrating on sculpture and painting, so this ring is amongst the last pieces of jewellery he has made, each piece of course unique.

The face is carved from walrus ivory, whiter than appears in the photos, set in oxidised and partially gilded silver with gold pin-point eyes, signed in monogram on the reverse. The head is 1 1/8 inches: 28 mm crown to chin, and the finger size UK M: USA 5
