Translucent Green Rocks

[Gypsy Heart]

Can someone help me with these. Found today in Northern Wisconsin along a riverbank. Some were on top and others I dug up They range from milky green to translucent green. I am holding one up to the kitchen light to show how you can see through some of them. Any idea?

Ok It doesnt break or splinter like glass. It was found away from any homes or buildings along a river that had no road close to the spot ....was about 1/4 mile through woods.....I am not saying it isnt glass slag....but then how did it get there? And there is alot more there in the river bank.

When I hold it up to the sun or light...I can see through it...its hard...I have to really hit with a hammer to try and break it.

Ok then,I'm going with the kryponite idea,Send me a chunk and I'll see if it makes me sick !

Beryllium? spelled right?

Maybe?

Beryllium, atomic number 4, is a brittle, steel-gray metal found as a component of coal, oil, certain rock minerals, volcanic dust, and soil.

Are you thinking of beryl?

On the link I gave (http://www.webmineral.com/help/Hardness.shtml)
It mentions different things, you have to rub them together to get hardness.
Example: You have an unknown mineral it does not get a scratch with your finger nail but it does by calcite which means it between 2,5-3 in hardness.

I remember a green rock I had as a kid in my collection that I thought looked simmilar. I thought it was Beryllium. Maybe Beryl. It was just a wild guess. http://periodic.lanl.gov/elements/4.html

"Beryllium is found in some 30 mineral species, the most important of which are bertrandite, beryl, chrysoberyl, and phenacite. Aquamarine and emerald are precious forms of beryl".

 

[Eu_citzen]

"Beryllium is a constituent of about 30 identified minerals, but most are rare. The most common beryllium mineral by far is beryl, 3BeO·Al2O3·6SiO2. This is a hard (Mohs 7.5-8.0), relatively light (spgr 2.75-2.80) found in granitic rocks, pegmatites, mica schists and similar environments, occasionally in huge crystals. One crystal was 9 m in length, and weighed 25 tons. Beryl is typically full of inclusions, milky but translucent, and of a greenish color. Clear crystals, which are much smaller but can still be of considerable size, are valuable gemstones. Pure beryl is clear and transparent, but small amounts of impurities color it very"

Could also be Jade your reffering to..

Miz Gypsy,I was thinkin ( I know scary huh ) My brother just bought onea them new fangled testers that will tell ya if it is glass,diamond,ruby,tourmaline etc.and i was thinking that mabey there is a jewelry store around your parts that may have one.So perhaps you could have it tested to solve this mystery ! I'm still stickin to the glass theory,I dont think there would be bubbles in a naturaly formed mineral,unless it were perhaps volcanic. But then again i been known to be tupid sometimes !

 

[Bigcypresshunter]

I dont think its Beryl nor do i believe its in the Beryllium family now. I should not have mentioned it because i dont know enough about it. I just threw that thought out there thinking someone more knowlegable than i on minerals would comment. It has been many years since I had that rock in my kid collection and I just remember it being green.

Hi Gypsy Elf
I like everyone else am guessing, but it looks like quartz the way it is fractured. I facet gemstones, there looks to be one or two in the picture that could be cut into a nice gemstone.

I would say quartz too, or possibly the lighter part of a chrysocolla sample or a light colored aventurine quartz.

I’ve found similar looking samples while out prospecting.

Good Luck and HH.

aventurine is also a variety of Quartz.
Gypsy any updates?
Yeah mineral shops can Id it, but not every one has one close by.

I've worked on chrysocolla slab walls that parts of were light and some parts dark. Some areas are a quartz chrysocolla mix. All of us prospectors know that chrysocolla and or quartz (preferably rusted quartz) are two of the minerals associated with Gold.
The mineral chrysocolla can be fat or lean in copper, the more copper, the darker the color.

I’m not arguing that Gypsy Elf's sample is chrysocolla, I'm only saying that I have found samples that resemble what is pictured.

And a light colored aventurine quartz:

 

[kieser sousa/rip]

I have to say it does look abit like aventurine If not for the BUBBLES.

 

[bedpanmoneyman]

Looks like aventurine to me Gypsy. I don't think you'd find anything from the beryl family of gemstones in your neck of the woods.

 

[rockhound]

Looks like green aventurine to me also.

 

[kieser sousa/rip]

I think that whatever they are they are pretty cool ! Wish I could find some.

 

[spiffyman]

very nice specimens

Gypsy,
Your stone is green calcite. does it at all feel waxy like? if so, you have green calcite...I am 99percent sure of it..

She seems pretty certain. What do you think GypsY? http://www.healingcrystals.com/Calcite_-_Green_Calcite.html Calcite - Green Calcite - These natural Green Calcite chunks glow with leaf-green color and are slightly translucent.

 

[kieser sousa/rip]

Kinda looks like it but NO bubbles.
