hooked Posted September 21, 2010 Share Posted September 21, 2010 Hi,Can someone please tell me what this is?It is not magnetic, it has a triangle shape to almost everything except the outside, It looks like it has rust one it. and its pretty heavy (dont know the weight)Thanks for the help in advance. Someone offered me a lot of money for it and I would like to know what it is before I sell it. It is larger than a quarter. Smaller than a half dollar.

Bedrock Bob Posted September 21, 2010 Share Posted September 21, 2010 it is a sulphide of iron/copper. Common "fools gold". If someone offered you a lot of money for it, TAKE IT. Quote Link to comment Share on other sites More sharing options...

hooked Posted September 22, 2010 Author Share Posted September 22, 2010 I'm going to guess galena crystalsI think you might be right but im not sure? if it is what you say, what would this thing be worth? Quote Link to comment Share on other sites More sharing options...
fredmason Posted September 22, 2010 Share Posted September 22, 2010 it is worth whatever you can get...TAKE THE MONEY!!!fred Quote Link to comment Share on other sites More sharing options...
Goldfinger Posted September 22, 2010 Share Posted September 22, 2010 I'm going to go out on a limb and say chalcopyrite.http://www.mindat.org/photo-56163.htmlSteve Quote Link to comment Share on other sites More sharing options...
Bedrock Bob Posted September 22, 2010 Share Posted September 22, 2010 The funny thing is that galena, chalcopyrite and iron/copper sulphides are all CUBIC. These crystals are not. Galena is always dark and lead colored (that I have seen)and rhombodedrical (yes, I know this is not the correct word) and chalcopyrite is peacock ore (to my best knowledge)and is multi colored and CUBIC. I have buckets full of sulphide crystals that look EXACTLY the same but they are not "triangular" (I believe triangular is the wrong word...tetrahexagonal? Rhombohedrical? Confusaximal?)they are CUBIC.The key to the ID is the shape of the crystals. I dont think any of us are correct so far except Fred. Quote Link to comment Share on other sites More sharing options...
Johnno Posted September 22, 2010 Share Posted September 22, 2010 I want to playhttp://www.mindat.org/min-3314.html Quote Link to comment Share on other sites More sharing options...
fredmason Posted September 25, 2010 Share Posted September 25, 2010 Jonno, come to the Gold basin Outing and we can play...Where is Reno Chris when we need him...it could be a psuedomorph...pyrite that replaced or formed over something else...take the money!!!Fred Quote Link to comment Share on other sites More sharing options...
Johnno Posted September 25, 2010 Share Posted September 25, 2010 G'Day FredWish I could. I think that's what Kat and I need. But I'm afraid it has to be put on hold. I'm going to miss out on your great food as well as all the great people. But there's always next year. Seems like you've adjusted to retirement pretty well. Now you just need to find that productive hole and you will be on cloud 9CheersJohnno & Kat Quote Link to comment Share on other sites More sharing options...

It is weird I have never seen anything like it no matter what size the "triangles" are, the are the exact same shape. It is very heavy for its size also. I would really like to know what this is and I know you guys are trying but I cant seem to find anything that is this shape...It looks like a triangle but its not, its kinda like a 3D beveled triangle from any angle you look at it.Thanks Quote Link to comment Share on other sites More sharing options...
fredmason Posted September 29, 2010 Share Posted September 29, 2010 I mentioned Reno Chris...have you contacted him? You might want to compute its specific gravity...that could give you a clue...especially if it is a morph of some type...good luck and remeber I said it first...take the money!!! just teasing....fred Quote Link to comment Share on other sites More sharing options...
