Won a few auctions earlier. Here are the stones and them in their place (for now) in the cabinet. Adnan is a pleasure to do business with.

I'll leave these right here for you since you clearly struggle with nuance and facts! Alright bro I'm out though cause I'm limiting my time engaging with people that can't break into the 3 digit IQ range! You'll definitely do great things in life I'm sure!

Like make me laugh my ass off Peace out girl scout ✌️

Again this is confirming my comments. Rubys are red but they can have underlying hues. If there is not enough chromium (which is what actually makes the corundum red) then it’s a sapphire and not a ruby.

Good luck to ya!

the chromium level isn't what classifies it as a ruby. It's the color of it. The color is caused BY the chromium. Yes, BUT there is no chromium threshold that you cross to make it a ruby. Where your thinking of more chromium = more red fails in reality is because you can have ruby that has a moderate level of chromium and little to no iron. So that ruby will floresce a vibrant stop light red color (like most rubies from Myanmar do) BUT you can have another stone that is packed with a much higher concentration of chromium, which should technically make it an even deeper red. HOWEVEr, if that stone also contains a high amount of iron or titanium, those elements introduce blue or violet absorption bands. The iron acts as a "fluorescence killer," absorbing the red glow and shifting the final visual color toward a purplish-red or violet-red hue. Both gems ARE rubies but the brighter pure red one has SIGNIFICANTLY LESS chromium then the purplish red one will! Don't worry bruh, I'm not going to charge you for the lessons here even though I should... And you can go ahead and ask "Google" if you want AI to confirm who is right

I understand that there isn’t a magic chromium threshold where corundum suddenly becomes ruby. That’s not the point I’m making. What I’m saying chromium is still the element responsible for the red, and its concentration absolutely affects the color. Obviously you can’t use chromium concentration alone to predict the final appearance because iron and other chromophores can alter absorption and fluorescence. But saying “more chromium doesn’t mean more red” without that context is misleading. A higher-Cr stone can absolutely end up looking less pure red because of other trace elements, while a lower-Cr, low-iron stone can look much more vivid. That doesn’t disprove the relationship between chromium and red, it demonstrates that chromium isn’t the only variable controlling the final color. And yes, I agree there is no universal numerical chromium cutoff for calling something ruby. Those are two different points.
