14.8 x 4.4 x 3.9 cm. This is a large crystal of "ametrine" (combination of yellow and purple tones) quartz from Bolivia, which got its weird form and silky luster from natural etching. If you hold it up to the light, you can see that it is very gemmy through the center; these are sometimes cut into stones, often showing the multiple colors. This one has a beautiful purple glow and a golden band running through the center/top.
