On peut distinguer les sceaux \u00e0 encre, tr\u00e8s utilis\u00e9s depuis l’antiquit\u00e9\u00a0en Asie orientale et qui permettent de signer des documents de papier, et d’autre part les sceaux en relief qui impriment un motif sur une mati\u00e8re molle qui va durcir rapidement\u00a0: argile humide,\u00a0cire \u00e0 cacheter\u00a0chauff\u00e9e \u00e0 la flamme, plomb.\u00a0D\u00e8s l’antiquit\u00e9, il a \u00e9t\u00e9 remarqu\u00e9 qu’il \u00e9tait extr\u00eamement difficile de r\u00e9aliser un faux sceau convenable \u00e0 partir de l’empreinte authentique d’un sceau en relief.<\/p>\n

Cachet en nacre taill\u00e9e d’\u00e9poque Charles X.

Objet de collection dont les plus anciens exemplaires datent de quatre mill\u00e9naires avant notre \u00e8re. Le cachet fut d’abord utilis\u00e9 pour apposer la marque personnelle d’un personnage pour garantir le contenu d’une boite ou d’une enveloppe, authenticit\u00e9 d’un document. On utilisait d’ailleurs aussi le terme sceau. Le petit cachet personnel est en effet utilis\u00e9 en\u00a0 Europe depuis le moyen-Age.<\/p>\n

Pendentif cachet en or jaune 18 carats orn\u00e9 de pierres fine. Epoque : 1910-1920.

Ce peut \u00eatre une bague mont\u00e9e d’une intaille de pierre dure, ou un chaton d’or grav\u00e9 en creux. Mais plus nombreux sont les sceaux emmanch\u00e9s, form\u00e9s d’une pierre dure grav\u00e9e en intaille: cornaline, grenat, saphir, cristal de roche, agate; certains sont m\u00eame des intailles antiques. Ces petits cachets sont parfois des bijoux que l’on pend \u00e0 une cha\u00eene ou \u00e0 la ch\u00e2telaine; comme les bo\u00eete , c’est souvent un objet de cadeau.<\/p>\n

Ces cachets sont de tailles variables: on en trouve de minuscules ench\u00e2ss\u00e9e sur de jolies\u00a0\u00a0montures d’or cisel\u00e9, d’autres mont\u00e9s sur poign\u00e9e d’or, de pomponne, d’argent cisel\u00e9, de nacre, de pierre dure, de bois.<\/p>\n
