Avalon Shell Abalone Shell Pendant Top Avalon shell refers to the nacre found on the inside of an abalone shell. This nacre is formed by layers of calcium carbonate, and it reflects light to create an iridescent shine. Size: 1.5cm Stored at home after purchase Unused It shines with an iridescent color depending on the viewing angle and is very beautiful. I think it will look great on a knit sweater even in the coming cold season. *Since there is no necklace from the beginning, only the pendant top is for sale.
