| General Info: |
Agate (achates) was named from the river Achates, now the Drillo, in Sicily, where the stone was first identified. It is cryptocrystalline quartz (micro crystals) usually with a banded pattern (although not always). |
| Additional Information |
| Needle Peak is located Brewster Co. Texas, S. of Terlingua and a little west of Big Bend national park. There are a multitute of moss colors found in this ara. (Also sagenite, and pompom agate.) My experience has been that the darkest green mosses will under-cut very easily, whereas the other colors seem to cut very well.
