About Amblygonite
A ambligonite é um mineral de fosfato de lítio, alumínio e flúor que ocorre em cristais de coloração que vai do branco ao amarelo pálido, verde claro e por vezes azulado. Embora não seja uma gema comum no mercado, os exemplares transparentes são muito apreciados por colecionadores de minerais raros e por joalheiros que procuram pedras incomuns. O nome deriva do grego "amblygonios", referindo-se aos seus ângulos oblíquos de clivagem. Encontra-se principalmente em pegmatitos graníticos, frequentemente associada a outros minerais de lítio como a espodumena e a lepidolite.
