Each Abalone Shell is polished to reveal their beautiful Iridescent color and brightness. Sustainably collected for smudging, art & crafts, and smoke cleansing. Available Sizes: 4 - 5 inches *DISCLAIMER* Items pictured are representations of what we have in stock. The items you receive might vary slightly in color and size, as they are all natural products. All Abalone Shells are hand picked and checked carefully before shipping. Abalone shells are natural products, so they will burn if you leave anything burning for a long period of time. The blemishes caused by fire are another form of their natural beauty. (To protect their beauty a little longer I suggest adding sand to the abalone shell.)
