Strange Rock Found. Need Help!!

[DiamondMiracles]

I found this rock by this creek that isn't even a mile away from Lake Erie. It was cool looking with the Water Horse egg look. The rock was very heavy too. When I found it, the rock had a crack straight down in the middle. Since I'm not an expert and I don't collect rocks, I decided to crack it open. Inside I found this black rock with tons of other crystals/rocks inside of it. I'm a research geek so I decided to see what it is. I looked all over online and couldn't find a thing that could help me. My parents said that the black rock is coal. I'm really confused because the crystals inside look exactly like diamonds. My mom and I did research from gems, diamonds, crystals, meteorites. Nothing seems to fit this rock.

The exterior suggests that its a pegmatite and the interior that of a basalt origin. Considering the shape its probably a remnant from glaciation in the region. Neat shape.
The exterior shows the most detail. Basically its a conglomeration of large crystals that has survived time to be as you found it.

Run it through a rock crusher and pan it! If you find free mil gold (which you just mite) hunt it's brothers and sisters. Some pegmatites, especially dark ones, are gold bearing.

We are currently doing that right now. Thank you so much!

What you have might be a weathered piece of kimberlite. Kimberlite looks like a breciated stone and has crystals enclosed. It looks like there were a couple of garnets...red/orange in color. One way you can tell for sure, is take a piece of the rock with the clear crystals and either remove the crystals or soak the whole small piece with the crystals (including the seperated crystals) in a plastic container for 24 hours using a solution of hydroflouric acid (which is obtained at Walmart at the rust remover shelf, and is in a bottle called WHINK). Be careful, that solution is very dangerous even when weak. If the crystals show signs of etching under a microscope, then they are not diamonds. Diamonds are pure carbon and impervious to the acid.
