In creating this remarkable necklace I selected huge end drilled Chinese Turquoise nuggets, sterling silver Bali bead between each turquoise nugget and an adjustable sterling silver lobster claw and chain closure. The necklace can be adjusted from about 18" to 20". The nuggets vary from 7/8" to 1 3/8" x 5/8" to 1" x 3/8" to 5/8". The turquoise nuggets are really, really big! I bought this strand of real Chinese Turquoise 20 plus years ago before dyed magnesite want-be-turquoise flooded the market.
