Hi there

I live in the lizard in sunny cornwall and have been fasinated with the rock and crystals we have down here, but me and my brother have been finding some wonderful specimens that i will be posting pictures of with this post hopefully,but more to the point....we were left by my great aunt a gem that glows a vivid orangey red kinda like a burning ember under a white LED..ive tested the hardness as much as i can by mostly trying to scratch the surface with a piece of topaz and nothing happened..no scratch notthing so the more i look into it the more we belive its a ruby but we are just trying to verify if it is or not so any hints or tips will be a big help.
Thanks alot. Tony. Just tryed to add pic no good so ill find another way. Thanks.

Hi Tony, and welcome to the site.
The shot is probably a quartz geode, or part of one, anyway.
If you read thru the posts, you will see, over and over, the futility of trying to ask for an I.D on a stone, unless you post photos, and other info to help define what you have.
take it to your local gem/mineral club, always a way to get opinions if you don't wish to pay for the I.D

Hi Unknown Gems and welcome.
Rather looks like quartz to me as well.
There are a few tests you could do to narrow down this unknown gem :wink:

The mineral is in the form of botryoidal masses, which narrows it down quite a bit. I'd feel safe in calling the mineral cruptocrystalline quartz or microcrystalline chalcedony (not true chalcedony). It is a nice specimen.

Humph. I see xls no botryoidal masses.
I'm not sure the term cryptocrystalline is still being used. Microcrystalline, yes.

The photo above is botryoidal chalcedony.
