Rare quartz with inclusions of star golden rutile from Novo Horizonte, Bahia, Brazil. Rutile develops six rays radiating from a central hexagonal crystal of hematite. It is an epitactic association between rutile and hematite. This delicate star would hardly have been preserved if it hadn't been preserved by the quartz that grew on it. Hard to find piece for high level collector.
