I’ve added great new specimens to the website in this Mexico Update. The update includes several mineral species for which Mexico is famous, including adamite, austinite, wulfenite, danburite and datolite.

I’ve just added the first of many specimens to come from the John S. White quartz collection. This is a superb quartz collection with wonderful specimens spanning quartz varieties, habits and localities of all kinds.
