Its a big handful of sheer beauty- filled with iridescent swirls of color- gold, silver & rainbow tones throughout! These are available in 3 sizes. This listing is for ONE shell, carefully packaged. Megastraea (astraea) undosa, common name the wavy turban snail, is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails. This species is native to the coast of California. All of our shells are real & unique. The majority of the shells we sell are intended for crafting purposes & are not specimens (unless otherwise specified); meaning that most will show evidence of their lives in the ocean. There may be natural variations such as but not limited to: growth marks, pinpoint holes, chipped points or edges, calcium build up, etc. WE DO NOT SELL “PERFECT” SHELLS- our shells are natural, beautiful, & imperfect.
