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.
