I have a rock that weighs 1172g and is about the size of a large fist. Resembles amber, did the hot needle test and didn't notice anything. Did the acetone test and nothing happened. Feels heavy and maintains warmth. Maybe glass? The black dots are paint from a spray gun. Any advice would be nice. I dont know a geologist. Thank you for your time.
Thurston County Washington
What a lovely agate!! Thurston county has a rich geologic history between the accreted terrain underneath the glacial sediments and the recent volcanics from Mt. Rainier. The Washington DNR geology website :https://www.dnr.wa.gov/geology is a good resource. If you want to learn more about the local geology, another good link is Nick Zentner's video series out of Central Washington University. http://www.nickzentner.com
The Department of Natural Resources there in Olympia has geologists on staff, as do the local community colleges and the Olympic NF Supervisor's Office. They should be available when our shelter in place is lifted.
The reason the agate looks like amber is because agate, a quartz mineral, can be translucent and comes in a variety of colors. Quartz is resistant to erosion and can often be found well rounded, due to being rolled around in rivers. You are very observant! What a nice find!
