New Members AnnaNova Posted July 23 New Members Share Posted July 23 Hello everyone, I am very new here, but I have been a very passionate amateur collector of pretty stones and minerals I am able to find around. Earlier this summer, I was diving at a beach in the Aegean Sea and found several interesting rocks that I would be happy to identify. Starting with the green mystery - I found it buried in the sand under the water. I realize it might be man-made, but it does not feel painted. When I tried to chip it with another regular rock, the other one got painted green but the green one didn't really chip or show any colors underneath. I know very little about these things, but I am wondering if this could naturally happen somehow. The other peculiar thing about this is that the stone is oddly light in weight. It is 10cm x 5cm. At the same beach, again underwater, I found some suspicious bones that I will post in the Fossil topic for identification, but I also found some other large rocks that had obvious veins in them. When I cracked them open, they turned out amazing. If you can point me to what these are as well, I will really appreciate it. Link to comment Share on other sites More sharing options...
Ludwigia Posted July 23 Share Posted July 23 I'm not at all sure what your green stone might be, but the veins in the other rocks are either quartz or calcite. Calcite would fizz under a few drops of a weak acid like vinegar essence, quartz would not. 1 Greetings from the Lake of Constance.

ynot Posted July 23 Share Posted July 23 The green piece looks like malachite, but that would not be "light". Could be melted then beach worn plastic- see if it will burn.(red hot pin.) The rest look like quartz/agate with crystalized vugs. 1 Link to comment Share on other sites More sharing options...
New Members AnnaNova Posted July 24 Author New Members Share Posted July 24 Thank you both for the information provided! For the green one, I tested and it is not plastic, has the exact feel and effect of stone, it is very hard actually, I could barely scratch it.

Unusual green color and shape, looks more like an industrial remain than a natural stone. But, never seen one like this before Edited July 24 by rocket 1 Link to comment Share on other sites More sharing options...

A streak test - color? Specific gravity? Link to comment Share on other sites More sharing options...
