This is a beautiful Abalone Shell Sun Pendant necklace.  The metal is silver plated over copper and the 18" Plus 2" extension (Total possible length 20") is imitation leather.  The Abalone shell in the center of the sun is just gorgeous! Abalone shell is known for its color of green with blues, purples and pinks running thru. Because these are made of natural abalone shell...no two are alike but all are similar as the pictures. Unique for yourself or as a gift!
