Certaines cellules du manteau sont responsables de la biomin\u00e9ralisation (la s\u00e9cr\u00e9tion de carbonate de calcium dont sont constitu\u00e9es la coquille et les perles) dans l\u2019hu\u00eetre perli\u00e8re, tout comme les humains ont des cellules qui sont uniquement responsables de la production osseuse. Ces cellules de manteau d\u00e9plac\u00e9es peuvent se regrouper, former un \u00ab sac perlier \u00bb (un ballon de membranes cellulaires produisant les perles qui se gonfle \u00e0 mesure que la perle grossit) et commencer \u00e0 former une perle qui peut cro\u00eetre au fil du temps.<\/p><p>Cette l\u00e9sion du manteau qui peut donner lieu \u00e0 la formation de la perle naturelle gr\u00e2ce au d\u00e9placement des cellules pourra se produire par exemple \u00e0 la suite d\u2019une attaque de l\u2019hu\u00eetre par un animal. Beaucoup de perles fines se d\u00e9veloppent dans le manteau car le manteau est le seul organe capable de secr\u00e9ter du carbonate de calcium et donc de former des perles sans intervention humaine.<\/p><p>Cette explication de la formation de la perle fine exclut la th\u00e9orie r\u00e9pandue du grain de sable principalement parce que le sable est inactif et ne p\u00e9n\u00e8tre jamais activement dans les tissus externes du manteau.
