Funny Green Rock…

[david bull]

So, I was out hunting arrowheads and ran across this funny looking rock.At first I thought it was a piece of glass but it seems to be made into the rock…

The only explanation I can come up with is it has quartz in it.
Maybe it came from outer space?

Do a search on green quartz crystals and go to images. Most of the results are links to its "healing power" and and places to purchase them. It could be worth more than just a very nice find. Very cool rock! It pays to keep your eyes open.

If you’re anywhere close to a University go see the Geology Department. Excellent free information.

I'm thinking Emerald.
Numerous ice ages have ground across the continent. Dragging materials from Canada south. Here along the shore of lake Erie in Ohio. All the way south of Columbus. Is mostly all glacial till and meridian material brought down from Canada. I believe that could be from Canada.

Canadian emeralds

According to his field notes, it was a rainy afternoon in August 1998 when Bill Wengzynowski, then a geologist exploring for base metals in the Finlayson district of the Yukon Territory, spotted something green. Thinking at first that it might be...

The metal looking rock around the beautiful green crystal could be chromium. A typical dopant that creates emerald in quartz matrix.
I truly hope you've found something truly special.
Don't break it up. So much more valuable in matrix.
I think you've found something really special.
Go back and look for it's Friends ...

It's beryl and the color says emerald. Wow. The host rock is quartz and was in a very coarse pegmatite base that broke away. That is one fine specimen.

Very cool! Everybody wants to hunt with you for arrow heads!

Hardness Test can help -
The hardness of a mineral is determined by scratching the mineral with a material of known hardness.
The materials that Geologist’s use to test mineral hardness are a set of minerals of known hardness called the Mohs Hardness Scale.
There are ten minerals in the Mohs Hardness scale assigned numbers from 1 to 10, where 1 is the softest mineral possible and 10 is the hardest known mineral.
The ten minerals and their hardness numbers are listed below:
1 talc
2 gypsum
3 calcite
4 fluorite
5 apatite 6 orthoclase (a common form of potassium feldspar)
6.5 Glass
7 quartz
8 topaz
9 corundum
10 diamond.

The natural angle of the cleavage can help too

Be nice to locate the cake it broke away from.

Whatever it is it's stunning.

Looking at it closer it appear to have 6 sides or hexagonal. Half of it imbedded in the host rock. R2-D2
Typical of calcite or quartz.
Both stones are most likely the same material.

I do not think it's tourmaline as the crystal structure isn't right. This crystal is not triangular in cross section. Usually tourmaline has somewhat rounded faces with striations sometimes. https://geologyscience.com/minerals/tourmaline/ This specimen is hexagonal and smooth faces.

What State?

North Carolina has some Emerald Deposits.

Odds of finding something like that have to be more than one in a trillion! Congratulations on your incredibly beautiful find!

I’m thinking maybe this was a trade item. I can’t say where for obvious reasons, but I have found lots of Indian relics in this area.
