Any views about this stone on the basis of SG and its appearance.

I would guess rose quartz, but keep in mind I'm not that familiar with physical properties of minerals yet, so there could be visual clues that I don't know to look for that would give it away for someone else.

I can't tell what color it is. Why didn't you photograph it on white?
Buy sounds like a quartz or chalcedony variety.

I have used dark colour cloth to properly expose the stone in the photo. On white color background stone might not be exposed properly.

To calibrate exposure, put a dark cloth next to the stone and move the camera until the brightness level of the full image is right for the camera to not over or under expose. Then crop out the dark cloth in the final photo. Good trick for opals on some cameras as well.

I don't get it. You can't crop out any effect the dark background has on the appearance of the stone, can you?

To clarify the dark surface is put beside the stone, not beneath it.

Duh, OK, I'm awake now. :-)
It didn't really need clarification, just reading ability. I was still thinking about the awful red background.
