Callahan Posted January 29, 2023 Share Posted January 29, 2023 Is this agate petrified wood? Most beautiful ones I have ever found. Color of honey and dark colored crystals are translucent Found in college station Texas in creek. Brazos river valley area. The watershed valley is loaded with p wood. I lightly sanded bottom and top of first rock in pic. many mineral experts please let me know if this is any rare due to size or what it is etc ? thanks bryan.

daves64 Posted January 29, 2023 Share Posted January 29, 2023 I'm thinking these are honey (or golden or amber) calcite. 1 5 Accomplishing the impossible means only that the boss will add it to your regular duties. Link to comment Share on other sites More sharing options...
Callahan Posted January 29, 2023 Author Share Posted January 29, 2023 Yes I agree after researching a little. Not the hardest material either. I could sand bottom pretty easy. Learned something new thank you. 1 Link to comment Share on other sites More sharing options...

Coco Posted January 30, 2023 Share Posted January 30, 2023 16 hours ago, Callahan said: It can also look like zoned quartz. To tell the difference between quartz and calcite, pour some vinegar on it and see if it bubbles. If yes, it’s calcite, if no, it’s quartz. You can also do a hardness test, quartz is harder than calcite.
