I've always loved traditional graduated roundel necklaces adorned by the Navajo people. Finding the variety of discs to produce these beauties has taken years. I buy 4 separate strands to put these pieces together. Sold in 28, 32 and 36 inches. The disc centers are around 3/4 in diameter tapering to 3/8ths. Sterling stamped cones and pure silver toggles. Photos coming soon! Also offered with Spiny Oyster
