The present invention relates to, in a method for crystallizing skeletal remains after cremating a dead body, a method for preparing a crystal of skeletal remains, comprising: (S1, a bone powder preparation step) recovering cremated skeletal remains, removing foreign matter therefrom, grinding the skeletal remains and then gathering the same (S2, a composition mixing step) preparing a composition of one natural mineral selected from lithium (Li), silicon (Si) and barium (Ba), a yellow soil powder and a natural vegetable essential oil in a predetermined ratio, and putting the same into a desired mold, and (S3, a mixture melting and crystallization step) carrying out crystallization by melting the mixture of skeletal remains at a predetermined temperature for a predetermined time, and then cooling the same and (S4, a separation and finishing step) separating the same from the mold frame so as to finish the same. Compared with a conventional prior art, the present invention intended to lower a melting temperature and add a deodorizing effect and an insect-proof effect, and intended to add an aromatic function to a crystal of skeletal remains so as to facilitate storage and accommodation, and selected, as a mold, a mortuary tablet model or a tombstone model so as to allow reverent storage in a normal household.La présente invention concerne, dans un procédé de cristallisation de restes de squelette après crémation dun corps mort, un procédé de préparation dun cristal de restes de squelette, comprenant : (S1, une étape de préparation de poudre dos) consistant à récupérer des restes de squelette incinérés, à en retirer les matières étrangères, broyer les restes de squelette et les regrouper (S2, une étape de mélange de composition) consistant à préparer une composition dun minéral naturel choisi parmi le lithium (Li), le silicium (Si) et le baryum (Ba), une poudre de terre jaune et une huile essentielle végétale naturelle dans un rapport prédéterminé, et les placer dans u
