Here are three specimen and the two smaller ones seem a little different than the large piece.
The large piece is so deep green that it appears black until you get some light on it. Any ideas?
Everyone really needs to trust themselves on their own identification, because 85% of the time their own thoughts tell them what something is..
Just wanted to add here.. Not sure if you've heard of the term "Road Cut" this is where the state has make plans to create new highways and simply cut away parts of mounds or hill sides.. thus revealing a variety of rocks and minerals.. While we have family in TN ourselves.. we tend to encounter these road cuts when new grounds for businesses are being built. The last road cut was are Bojangles near Johnson City.. The wife went into the restaurant while I was combing the hill side.. let's just say.. everyone stopped eating just to watch em search the hill.. ending up finding several ill formed thunder eggs and one was cracked up revealing the crystals inside.
Unless your finding garnets in the area, diopside garnets are unlikely. Stonewhisper is correct in my opinion. The larger bit is a fractured bit of black tourmaline though it looks to have some greening in it. Not to bad for color in the smaller bits.
Good stuff. BruntBear I wanted to ask a question. Does the blue looking Tourmaline turn your fingers that color when you wash the stones. Reason I ask I have a bunch of quartz crystals that has this blue looking stuff that looked black until I soaked it overnight in Super Ironout and it turned the liquid blue in the bucket. When I rinsed them off my fingers were blue black looking. The quartz crystals have a light blue tint to them.Thanks.
