The ability of a mineral to hold together is known as its hardness. It is a measure of a mineral's resistance to scratching or abrasion. Hardness is determined by the strength of the atomic bonds within the mineral's crystal structure.
Pearls are organic gemstones produced within mollusks like oysters and mussels. They have a smooth, lustrous surface due to their layers of nacre, a crystalline substance that gives pearls their iridescent glow. They are relatively soft, ranking around 2.5-4.5 on the Mohs scale of mineral hardness.
