There are/have been alexandrites of tens to hundreds of carats offered on the Asian market... The largest I've ever personally seen was 400-odd carats with a Gubelin cert. So size is not as unheard of as it seems, but the quality of the stone above would far surpass all of those (absolutely none of them were what you'd call "proper" quality, meaning a clear unmodified one color to clear unmodified another; most were visibly brownish or yellowish in one or both colors).

So based on that and based on its very suspiciously even looking color (looks exactly how a synthetic/simulant does when flooded with incandescent light), most likely not natural - but you can always get it checked.

No. it's probably synthetic corundum or glass. There's absolutely no color change either.

Alexandrite colour change is usually blue/ green in daylight to purple/ red in incandescent light. It’s rare to get an Alexandrite over 2 carats and rarer still to get a flawless one. There are other colour change gems ie garnet, sapphire and fluorite. Synthetic Alexandrite in huge sizes were very popular in the 60s and 70s (normally a purple or pink to red colour) and there is a current impressive synthetic that shows the blue green colour to violet red.
This is my very small Alexandrite.

My guess is synthetic corundum based on the clarity, size, colour change, cut and setting.

Is the stone in the OPs photo even meant to show a color change? I just assumed it was incandescent/yellow light in both photos.

If one of them is meant to represent daylight then OP, not alex, and not really a color change stone either. 99% chance that it isn't natural. Alexandrites should have a very clear and distinct daylight color either between yellowish green and green, or between greenish blue and bluish green. And then change into what the above two photos show under yellow light.

I would say 99,99999999999999999% fake or synthetic something.

Not the first one here - not the last one...
