Hi, really only guessing with photo’s but at first glance it looks like it could be chalcedony except chalcedony has a hardness of 7. other than that could be a garnet?? hessonite. realistically you need to get an RI and specific gravity and this should give you a good idea on the stone.
Are you interesred in buying gem stones?We have got a lot gem stones but we don’t have many international buyers.If anybody can help with this,that would be really appreciated.
