December birthstone

La pietra dei nati in dicembre è blu: tanzanite, turchese, zircone.

Tanzanite
Scoperta alla fine del 1960 in Tanzania, si trova esclusivamente in questa piccola zona del mondo. La tanzanite presenta un colore blu-violetto intenso; spesso viene trattata termicamente per ottenere questo colore. Spesso acquistata come alternativa allo zaffiro, è aumentata in popolarità e oggi è apprezzata più per la propria bellezza e brillantezza che come sostituto dello zaffiro.


Zircone
Deriva dalle parole arabe zar e gun, che significano oro e colore; lo zircone si trova in una vasta gamma di colori come blu, giallo, arancione, marrone, verde, incolore e  rosso (il colore più pregiato). Per molti anni lozircone incolore è stato utilizzato come imitazione dei diamanti. La saggezza popolare attribuisce allo zircone il potere di alleviare il dolore, stimolare l'appetito, proteggere i viaggiatori da malattie e lesioni, garantire un caloroso benvenuto e per evitare gli incubi, garantendo un sonno profondo e tranquillo. I principali giacimenti di zircone sono l'area Chanthaburi della Thailandia, l'area Palin della Cambogia, e la parte meridionale del Vietnam.

 Turchese
 Il nome turchese deriva dall'espressione francese Pierre tourques o pietra turca; nato nel XIII secolo, descrive una delle più antiche gemme conosciute. Il turchese varia dal blu verdastroalle sfumature di cielo blu  e la sua trasparenza varia da trasparente a opaco. IL turchese è abbondante ed è disponibile in una vasta gamma di formati. E 'più spesso utilizzato per perline, cabochon, sculture e intarsi. Anche se la sua popolarità oscilla nella moda, è un favorito perenne nel sud-ovest americano.
