https://www.ebay.com/itm/313532311827 <<is this fake?

I'm kind of a newb, but I can see this guys fingers are still green from what appears to be a dye? Is this really just pink sapphire ruby, that has been dyed green?

I got a hexagon blue sapphire one time and it looked pretty convincing blue in real life, but under a light, it was red/purple colored. Does this mean it was also was dyed? I have several Rough Rubies that are legit, no way it was faked you can tell by looking at it. (with the exception of one that looks like it was sliced with a blade to make it more hexagon.)

Are there green / blue hexagons this big with the triangles out there for a cheap price that have similar characteristics to the ruby? Tell me everything you know!

I love natural hexagon rocks, because it reminds me of collecting them in video games!

Regards,

There is nothing about the posted stones on eBay which resemble natural emeralds.

Emeralds should look like this. Cosquez Mine, Colombia:

They look a bit like this 1360+ carat emerald available here for $54.

These appear to be dyed corundum as you've guessed, given the shape and raised triangles on the terminations. They even glued some black stuff on to try and mimic matrix. Not a very convincing fake, to the point I wonder why they'd bother with such a bad fakr, but crystals of this type (maybe a particular mine in India?) tend to be an unattractive sickly grey-pink and are often dyed--their lack of porosity and transparency means the dye basically has to coat them to give a noticeable color and isn't likely to be long lasting, as you can see from where that color shows through.

These look like the "rubies" I have. Are these corundum, or sapphires? If they are faked, they sure found a neat way to do it...

If I could find the same consistency in other colors that would be nice.

I recently bought something similar to this https://www.ebay.com/itm/313277704405 for 26USD best offer.

I also got these, that look just like the picture. https://www.ebay.com/itm/313479791263
And I also got these https://www.ebay.com/itm/353268001668

What did I really buy? I like them regardless if they are natural. :D

Newguy, your question of what did I really buy? Is what ever your reason for purchasing them is. You tell us which you have because you liked it. I have purchased much of the same direct from the tradeshow countertops, but sold as what it is, it's when it is sold masked as something that it is not can be the problem for some. The last eBay item in your list I found interesting as it is facet grade Ruby of course it is, Mozambique questionable, as much of this type of material is Rose cut faceted, glass filled and dyed and Indian, makes it facet grade but not what most in the industry consider to be faceting grade material .

Not red enough to be ruby, at least in the very recent western sense of the word, so pink sapphire or pink corundum depending how picky you want to be.

To be clear, the examples in thr first post are fake emerald, real low grade corundum or sapphire.

Pictured in the second are classic littlr crystals, lots of locales produce similar little ruby/pink sapphire crystal sticks. Those should be fun if they actually send what's pictured, and you might even get some sheeny star material. The first one cpuld be Indian corundum. I'd be suspicious of it because the color and translucency are a little unusual for what's commonly available. It may be lead glass filled, oiled or resin filled, treatments which are even done on really cheap rough that could never be faceted even after treatment.
Overall, some of these could be fun specimens of corundum, others may be too manipulated to have much value outside of mild novelty.
