This thing is dark orange when shining light through it, and looks brown when shining light at it. But yes, I am in NW Indiana....lol.Glacial gravels follow northern Indiana border. I sent samples for assay to assayer in Randsburg CA area once. Assay came back glaucophane a common mineral found in Japan. Yes, abundant glaucophane is found commonly at western coastal ranges often in association with Jadeite. Indiana glaucophane usually bluish gray or blue-green when cleaned with water. Colors can be blackish and a couple pieces were hard enough to be jade, impossible to split just like shrapnel irregular curves shaper than glass. Glaucophane normally splits easy and rubbing on fine black sandpaper gives a clean bluish white powder. If you see yellowish/brown steak or powder it is not glaucophane. It can be lavender also but so rare here.
Thats what a friend said...Orange calcite. Gonna do the scratch test soon. I put them into my tumbler to clean them up some.Found a reference to brown Indiana calcite.
I think you are right, thank you.Google black amber and click on images
You mean on glass?I'm guessing pieces of large garnets. Without density testing, it's almost impossible to be absolutely certain. A streak test would help, too.
