Tanzanite

Les tanzanites sont garanties d’origines naturelle par gemmologue diplômé.

Attention aux lots imposants de plusieurs centaines de carats de « Tanzanite » proposées à petit prix ou sans réserve, il s’agit le plus souvent de Quartz de faible valeur, teinté en bleu (ou de béryl/quartz teinté en vert pour l’Émeraude, idem en Rubis). 

Variété : Tanzanite 
Nombre : 4 pièces
Poids : 4.52 carats soit 0.90 gramme
Taille : cabochon
Dimensions : ≈ 7 x 5 mm ±
Couleur : bleu à bleu-violet 
Clarté : inclusions visibles, très belle qualité 
  
• Envoi sous 3 jours partout dans le monde en mode postal suivi et recommandé.
• Possibilité de grouper les commandes pour réduire les frais de port.
• Une garantie gemmologique est jointe à chaque commande.
• Je suis gemmologue diplômé de la GEM-A de Londres. 
• Chaque gemme ou chaque lot de gemmes est bien identifié avant sa mise en vente.
• Je réponds à toute question dans les 24 heures.
