A beautiful complex lattice of rutile crystals in polished quartz. These rutile crystals have bright silvery lustre that really catches the light, looking almost metallic. With magnification, the rutile crystals are very three-dimensional. Of course, enclosed in the quartz every intricate detail is preserved, and the quartz is highly transparent.
In addition to rutile, there are two small rhombohedral crystals that at first glance look like they could be siderite, but as luck would have it, the cut at the back of the piece revealed that these rhombohedral crystals are hollow – they are pseudomorphs of goethite after siderite. Inside one of them are tiny crystals of pyrite.
Anyway, this is a super rutile in quartz first and foremost, from the John S. White collection.
