Gr\u00e2ce \u00e0 leur prix accessible, les diamants de synth\u00e8se offrent des possibilit\u00e9s de choix totalement nouvelles.&nbsp;<\/p>\n<p><b>1) Poids | Taille (Carat)<\/b><\/p>\n<p>Les diamants s&rsquo;expriment en carats (1 g = 0,2 ct). La taille de la pierre joue \u00e9galement un r\u00f4le essentiel dans la brillance du diamant, et nous recommandons de choisir des diamants \u00e0 partir de 0,3 ct (environ 4,50 mm, selon la taille), que nous proposons. La pierre parfaite se situe entre 0,80 et 1,50 ct, mais cela d\u00e9pend ensuite de chaque client. Ce qui est trop grand pour l&rsquo;un peut \u00eatre trop petit pour l&rsquo;autre, nous vous laissons donc juger vous-m\u00eame quelle est la bonne taille de diamant de synth\u00e8se.&nbsp;<\/p>\n<p><b>2) Couleur (Color)<\/b><\/p>\n<p>Ici, la recommandation est claire : \u00ab incolore \u00bb. La couleur, avec la taille, fait partie des deux facteurs cl\u00e9s du choix. Les diamants sont \u00e9valu\u00e9s selon les 4C (color, cut, clarity, carat) et la couleur est class\u00e9e sur une \u00e9chelle de D \u00e0 Z, o\u00f9 D correspond \u00e0 une pierre parfaitement incolore et chaque lettre suivante indique une couleur d&rsquo;un degr\u00e9 inf\u00e9rieur. La cat\u00e9gorie des diamants incolores comprend les lettres D | E | F. Les diamants de synth\u00e8se ont g\u00e9n\u00e9ralement une meilleure couleur que les diamants naturels et sont donc souvent disponibles dans ces teintes premium, alors que les diamants naturels courants sur le march\u00e9 atteignent une valeur de G-H.&nbsp;<\/p>\n<p><b>3) Puret\u00e9 (Clarity)<\/b><\/p>\n<p>Les inclusions internes des diamants peuvent \u00eatre consid\u00e9r\u00e9es comme leur empreinte digitale. Chacun en a de l\u00e9g\u00e8rement diff\u00e9rentes, situ\u00e9es \u00e0 des endroits diff\u00e9rents et de tailles diff\u00e9rentes. Les diamants de synth\u00e8se sont plus purs que les diamants naturels. Les inclusions influencent la r\u00e9fraction de la lumi\u00e8re dans le diamant, c&rsquo;est pourquoi nous recommandons de privil\u00e9gier les degr\u00e9s de puret\u00e9 IF, VVS1, VVS2, VS1. Tout le reste repr\u00e9sente, de notre point de vue, des puret\u00e9s en dessous de la moyenne.&nbsp;<\/p>\n<p><b>4) Taille (Cut)<\/b><\/p>\n<p>La taille est la magie m\u00eame qui transforme un morceau de pierre brute grise en un diamant \u00e9clatant et magnifique. Les tailles ont elles aussi leur propre \u00e9valuation, que vous trouverez sur le certificat du diamant avec les autres param\u00e8tres des 4C. Si une pierre est mal taill\u00e9e mais poss\u00e8de la meilleure couleur (D) et la meilleure puret\u00e9 (IF), elle perd de sa valeur, car personne ne veut d&rsquo;une pierre qui ne scintille pas. Nous recommandons de vous en tenir strictement aux tailles les mieux not\u00e9es : IDEAL, Excellent, Very Good. La combinaison id\u00e9ale est Ideal | Excellent | Excellent ou 3x Excellent.<\/p>\n<p class=\"\">Si vous avez une question concernant les diamants de synth\u00e8se, envoyez-la-nous \u00e0 :
