Abalone (from Spanish Abulón) are medium-sized to very large edible sea snails.
The shells of abalones have a low and open spiral structure, and are characterized by several respiratory holes in a row near the shell's outer edge. The thick inner layer of the shell is composed of nacre or mother-of-pearl, which in many species is highly iridescent, giving rise to a range of strong and changeable colours, which make the shells attractive as decorative objects, and as a source of colourful mother-of-pearl.
The dust created through the grinding and cutting of abalone shell is dangerous; appropriate safeguards should be taken to protect a person from inhaling these particles. An N95-rated dust respirator, a ventilation system, and wet grinding are requirements to working the shell safely.
