Black Cabochoned 1970s Egyptian Revival Triple Strand Collar De Chien Necklace is a dramatic yet classic way to wear black. The architecturally curved and shaped collar sits perfectly on the neck as the three bands come together in the back. The center is 1 5/8 inch wide. The piece is approximately 14 1/4 inches around. There is a 2 1/2 inch space in the back now, but is does have some give, and you should be able to adjust it to your neck.
