Ametrine (polished slab) (680 carats)

Item Description

This is a unique variety of Quartz from the finest occurrence in the world. Ametrine is a naturally occurring purple and yellow bi-color variety that is formed by a unique twin law ("Brazil Law Twinning") where two separate individually colored crystals are intergrown to form an alternating "radiation" pattern of purple and yellow triangles when viewed down the c axis. This two colors are oriented from these crystals to cut the famous bicolor gemstones. Here we have a natural, bi-color purple and yellow, colorful polished slab of Ametrine. The piece is nearly water clear in areas and shows true NATURAL (UNHEATED) yellow Citrine, which is incredibly rare in nature. A very cool representative "slab" of this material that is only found in one place in the world in this quality and capacity! Weight = 680 carats (130 grams).
