In order to post multiple photos in the same post, you need to use the PREVIEW button after uploading the first photo. This will open another set of dialog boxes that you can use for the next photo. When you are finished with the next photo, you can hit the preview button again for a new photo. you can do this up to 15 times, and when you have checked everything, then hit the SUBMIT button to post all your photos.

HI Steven!
Ok, there are different opinions regarding the quality of a red corundum, especially regarding up to which clarity a red corundum should be called a ruby. I studied gemology in Germany (Idar-Oberstein), and their opinion (which is what I learned) is that a corundum should show the two lines in red at the spectroscope to be considered a ruby, which means it MUST contain chrome ("Ohne Chrom kein Rubin!"), no matter how clear it is. The same rule is said for emerald among green beryls as well.

I agree except it NOT ruby; Ruby is the gemmy clear form which this clearly isn’t, just red/pink corundum. There is enough misinformation out there with regards to valuable gemstones. While ruby is a red corundum is true, the reverse is absolutely not, red corundum is merely red corundum, not Ruby unless it's clear. Ditto with sapphire which is all non-red corundum.
As a mineral forum I think we should be setting an example and being as accurate as we can be. And not encouraging the scammers out there by reinforcing their lies or getting peoples hopes up about fantastic wealth. I find it disappointing the ruby be presented here as an answer when it so very clearly isn't. |

| Maybe the label wasn't wrong for this specimen being from North Carolina? Chunky Gal Mountain, Clay County NC seems to be a possible location for this specimen assuming the green minerals could be Actinolite or another Amphibole? Anyone here familiar with that locale?
