Rare Red Beryl Perched on a Garnet Replaced (Pseudomorphed) by Hematite with Sanadine Feldspar Coating with Bixbyites ? Location: Thomas Range (Topaz Mountain) Juab Co. Utah. Thumbnail (see photo for more details). Here we have a really interesting and rare combination specimen. We have a garnet that has been replaced (pseudomorphed) by hematite with and outer ?shell? of Sanadine feldspar crystals with a red beryl crystal perched on it with Bixbyites. When it comes to red beryl Utah is the place. Red beryl was first discovered and described by Maynard Bixby from the Thomas Range (type locality) in the late 1890s. By the way Maynard Bixby also first discovered and described bixbyite from this same locale. First let me just say that the combination of these minerals (on the same specimen) is rare. The beryl is sharply formed and has a raspberry pink color. The ?original? garnet crystal has been pseudomorphed by hematite and then over coated with a ?coating? or ?shell? of well-formed and sharp white to off-white colored sanadine feldspar crystals.
