Is this alabaster mirror fugly or not?  

yeah I thought of that too ...
as in a reflecting pool. You could look at the night sky without looking up. Like when you are blazed and dozing off...?
But seriously, I agree most with tktoo... the scale is what struck me first. It's massive. Very striking though.
Mark, I like that you bravely try different stuff. I like your lack of fear, and your openness to critique. Not everybody has the ability to do that.
I like round stuff. This reminds me of my 1980's mirror with the thin black rubber edge. it's the only thing I still have from that time. I think it came from the original "Z" Gallery, when everything in it was black and white. Now the Z gallery makes me want to barf.

So many thanks to all.
I actually had the patio in mind when purchasing the beast. I then had my handsome maintenance man drill holes and hang the plump piece. He was not able to hang it high enough on the chosen exterior wall due to the exterior wall lighting. So...inside it came, and he drilled another round of holes, and rehung as shown above. Perhaps I have yet to see an eye pleasing marriage between "light classical" and MCM, but somehow this one is growing on me. I also enjoy overscale -sized mirrors, as they do add considerable visual space to a room...but possibly the chunky/clunky frame is what is killing this wall/look. I so appreciate all of your input. What if I were to hang a couple of vintage meat cleavers on either side of the mirror? or install a curtain rod above it and hang some tie back drapes? But I'll probably just re-donate it to a fav local charity.
What would Liberace do?

ps. I do like the way that the stone mirror frame helps the nasty tiled stone (building) support beam in the lower posted snappy.

It's a keeper
The scale is great, The molding work is simple, and the material..... fuggetaboutit. You have a very good eye my friend.

so shoot me
I think it kinda works

I love alabaster,
especially when it's simply done and on a scale like this (vs some fussy little tsotchke). I like this mirror frame a lot. But my first and lasting impression, no matter how many times I look at the pics and try to talk myself out of it, is that it's too heavy for the sideboard under it.
buzzed on nothing stronger than dark chocolate,
*spanky*

In the photos
The mirror certainly becomes the focal point of the room. If that's what you're going for, then cool.

I want my pants to be the focal point of every room....every day...every night...
why not?
Aunt Mark

Well
Whenever you're not in the room... the mirror wins.

Its a portal, to a universe where Mark is obliged to wear burlap underpants and the only thing he has to to drink is Claytons.

You folks are too damn funny.
Bahahahaha!

FTW!
Now I just have to rid my head of the image of Mark in burlap skivvies.

Reflect on this...
Dear Aunt Mark,
Love massive round mirrors and THAT one is fab!
Love that it is not wood framed and feels organic with the stone; adds a cool elegance that can reflect 'hot pants' while adding the shine and bling that all interesting rooms need reflecting light and life.
I have mixed massive round mirrors (although none as wonderful as that one) with low long lean credenzas before and found it works best for me if I center it (think Art Deco vanity sort of) ...but the trick I think in my humble opinion is to lower it to just above the furniture piece ( 3- 6 inches or so)...that anchors the mirror and the furniture together and I think would create a wonderful juxtaposition between the warm wood and cool stone almost touching...then the weight might better hold that side of the room as an illusion of one stronger piece.
To my eye, when it floats so high above and is clearly so heavy it distracts me slightly with thoughts of the horrors a crash would wield and the pants that would no longer be 'SMASHingly' reflected....
and that would be a shame 😉
