About Star Ruby
O rubi estrela é uma variedade de corundo que exibe um asterismo de seis raios, causado por inclusões aciculares de rutilo orientadas em três direções e visíveis ao mover a pedra sob luz focada. Os melhores rubis estrela provêm de Myanmar e exibem uma estrela nítida e perfeitamente centrada sobre uma cor vermelha rica. A pedra estrela mais famosa do mundo, o Rubi Estrela do Rajá, com 138,7 quilates, encontra-se no Museu Americano de História Natural.
