Hi,

what locality is the specimen from? Did you test the hardness etc? Difficult to say from the pic.

Am from czech republic and I found him in nature, is approximately 15 cm high. Already me at home costs several years and a little on him seated dust. Photo is acquisition mobile with speed lamp, stone is without preexposure darkly green when almost black with little ones shiny crystals, he looks like metal but is lightweight with porous surface. Give out of him break off tiny parts perhaps 1 millimeter big but are hard. A according to different pictures what am found, really he looks like silicon carbide.  Thanks for responses and excuse my English

Hi YAMAnth,

yes, it is SiC. No doubt!

in other words (in summary): artifical garbage  - Sorry

SiC alias Carborundum !

You should however keep a little piece of it, as it is extremely hard - around 9,5 Mohs  and therefore the ideal tool to identify diamonds, if you ever happen to find some ;-)

Hello,

First of all: Check the hardness! If >9 then most likely SiC.

If you like the piece, keep it! Nice or ugly, treasure or garbage depends on yourself!
