Poison Green Moldavite

Posted by Kristi Hugs

Oh, jeez, leave the poor guy alone. He's just trying to make a living....

It does whet my appetite for a piece of that most excellent rock, though. I never heard of moldavite before.

Does anyone sell it sans "ayurvedic fire" or jewelry?

I was taught that a Moldavite is formed when a meteorite impacts the soil and fuses the terrestrial quarts into glass and the patterns form from the cooling of the glass as it’s blasted through the air.
I don’t have problems with minerals and energy but do have a problem with metahippies who don’t know what they are talking about. Too many of them out there.

I never heard of moldavite until i watched a show last night and seen them. Anyways when i was a child about 8 years old i was playing in a stream like kids do flipping rocks looking for crawdads and i found this big green chunk of i thought was glass but thought it was neat so i kept it. Im 43 years old now and still have it today. It never really crossed my mind that it coukd be anything else but glass. But i always wondered why it was so thick i. Never seen glass that thick before and it is green with bubbles in it. Its a big piece id say 6 inches by 4 inches and pretty heavy ill have to take pics soon as i remember where i put it. But deffinetly going to hunt it out snd see if its moldavite or just a big piece of green glass.

> green with bubbles

The bubbles exclude moldavite.

Being found, assuming it wasn't transported by humans (trading?), on the North American continent should also exclude it from being moldavite. By definition, moldavite is "A green natural glass originating from the impact of a meteorite in Bavaria 15 million years ago", so I would consider the NA continent outside the zone of this tektite deposition.

And yes as Uwe states, visually identifiable bubbles would exclude a tektite.

I think perhaps the Minestry of magic should be consulted on this one.

Hi Danny,

Could you post a picture?

In my region (Pennsylvania, USA), a big chunk of green glass-like material with bubbles would almost certainly be slag. Slag is a waste product from iron furnaces, which operated in the area for the better part of the last two centuries. Another possibility is that your rock is a piece of waste glass from a glass plant, depending on where you are located.

Without a photo, this is just speculation on my part.

Only note - visible bubbles do not exclude tektites. See these examples of great bubbles in moldavites:
And small bubbles are absolutely common in tektites.

Thanks, Lukáš. In fact, very large bubbles.
Gregg Little April 02, 2019 06:42PM
Sorry, I stand corrected as tektites do get bubbles. Though they do appear to be isolated and more rounded compared to slag glass where there are often many bubbles with irregular and stretched appearances, probably due to flow.
Sorry, only registered users may post in this forum.
