Abalone Shell Golden Earring 1.5 Inch Gold Filled Abalone Shell Earring. 1.5 Inch The abalone shell is the crown jewel of the Pacific; its iridescent colors are enchanting. Abalone is a member of the same mollusk family that includes clams, oysters and mussels. Some call the Abalone's iridescent shell lining Mother of Pearl (which is what the lining of the oyster is also called). This lustrous lining is made of alternating layers of calcium carbonate and conchiolin. Abalone shell lining has been highly prized by jewelry makers for centuries; perhaps because it reminds us of the beauties of the ocean on a sunny day. Simply cool beach jewelry. Wearing it will make you feel light hearted and adventure hungry.
