Presumably Something Cool

[JustinT]

I found this rock in CO south of Lake Granby near the river. I have not a single clue as to the specifics. The larger rock weights approximately 272 grams. A small portion broke off during my flight home back to MS, so I decided to crack it open! I am unsure if it is even a meteorite, but it is still pretty cool!

Hi Justin. Welcome to TreasureNet. Because of the fiery entrance into the atmosphere, it should show sign of some melting. Most meteorites are comprised of iron.

What are the characteristics of this rock that made you think "meteorite"?

 

[Art_Blade]

Use magnet to check iron content but doesn't look like a meteorite. Maybe next time....

It almost looks like a type of kimberlite - could be worth more than a meteorite :O (which means look for diamonds) I'd double check your meteorite theory first before you go smashing it to bits then if it isn't look for shineys

Thanks for the replies, y'all! A miner from CO said it was a moon rock, so I took her word for it. This does look like kimberlite. I don't want to jump the gun, but there are clear gems embedded EVERYWHERE! There are also shades of green (looks like copper that's been oxidized or some form of tarnish). A friend from high school is offering to professionally slice the rock. Any advice for me? I'll also post my new findings in the gem and mineral forums if allowed. Thanks again!

My advice is not to let your friend do anything unless you're there for the entire process. Doesn't take much or long to cut a slice in order to be sent to a lab or wherever. It most likely isn't a meteorite though. So, in that case, a slice isn't needed at all, and you just need to strategically smash it to check the insides for hosted diamonds. If there are any ore minerals you'd be able to scoop them up and pan them still.

I have begun the smashing process. It feels cool to mine for diamonds in my backyard lol I'll add photos of any, if any, finds!

show some pics of the innards...i'd like to see if it was a kimberlite...it would look almost like a breccia with little bits and pieces of a bunch of different minerals in it

 

[JustinT]

The last photo is through a magnifying lens. It looks cool if nothing else.

Doesn't look much like a kimberlite close up and I'm not that well versed to tell you exactly what it is, but it did look cool ...keep looking though, and you will find something. Meteorites are my favorite to look for because they require no special set up circumstances or location to be there. Gold chooses where it wants to be and if you don't live near a gold bearing area, you will have a hard time finding it. Meteorites don't listen to mother nature, they attack it

All I can tell you for certain is that it is not a meteorite. Sorry I cannot tell you what it is.
