About Simpsonite
A simpsonite é um mineral de tantalato de alumínio muito raro que forma cristais hexagonais tabulares, normalmente creme, amarelo pálido ou incolores, com um lustre vítreo a gorduroso. Ocorre em pegmatitos ricos em tântalo, sendo os exemplares mais conhecidos provenientes da Austrália Ocidental. A sua raridade extrema e a pequena dimensão dos cristais tornam as pedras talhadas uma raridade absoluta para colecionadores especializados.
