I did not know that Walter Schluep passed away March 23 at the age of 84 until I saw an obituary for him in the April 23 issue of the Globe and Mail. It’s detailed and well worth reading:
I feel fortunate to have five pieces by this talented designer. You can see them here.
This 18k gold necklace with an abalone inlay is one of my favourites; it can also be worn as a brooch and the unique rectangular chain feels substantial in the hand.
