I LOVE that it's a Montana sapphire and unheated! Nice, big size and the cut, as @mellowyellowgirl said, is fabulous. I also agree with her that this is a unique shade which may not be for everyone. I wouldn't expect too much in terms of saturation. I assume your wife has expressed a desire for this specific sage green coloration?
 
Beautiful. To add to the above, the color has a strong gray overcast which is not always a bad thing, Gives it a 'seafoam' color in this example. Could be more saturated (less gray, generally considered better), but you almost definitely won't find that in a large no heat Montana without a lot of time/searching. I'm also not sure if would it be the 'same' color family if we changed this parameter really - it would likely be more dominant green or blue (intuition, not an expert).
Maybe theres a comparisons at these dealers who have nice Montanas, if you haven't seen them already.
But overall great stone if she likes this color.

It's almost sort of a soothing green, isn't it? Andrew calls it "silvery" and "muted," which I think are perfect qualifiers. I like this color too, despite the gray.

Usually those descriptors are red flags, but it seems to work here, yes - of course, assuming it stays pretty in most lights ( though I know you mostly care about natural light)

You are so right about that! Usually red flags, but sort of inherent to/desirable for this particular shade. You nailed what I was trying to say. :)
 
As long as you believe your wife will love the colour, this will be an excellent buy. Beautiful stone, well cut, has character and won't go dark no matter what.

Ansokutejy agree.
But I’ll add
Plural. Colors. It’ll be shifty. Moody.
Some people really like this aspect - some don’t. How silvery is silvery green? It is still lively at its most shifted or desaturated? A lot to consider in lighting environments she’ll be in, frequently or no, especially for an engagement ring not an occasional ring.
Is your wife involved in this pick?

Wow Montana Sapphire sliglty greyish blue green (seafoam) is my favorite Sapphire color. Absolutely stunning piece of nature Art. The inside of a Montana Sapphire is one of a kind, under loop or microscop is an fantastic world like under water world. I call these guys mystic river stones. Super rare to get Montana Sapphire with more green than blue, most stones are to included and must heat, than the stone mostly more blue or remove the green completly. And unheated with so small inclusions, super cool in this size. I would be very happy when im ur wife!
 
Good cutting and the stone looks very clean and sparkly.

DK :))
 
Ooohhhh, I absolutely love this one! My avatar ring is a color shifting sapphire and I absolutely adore it. I love that the color is unique and hope your wife loves it too!
 
Okay I finally realized what this color reminds me of - less saturated alexandrites in daylight color! Still not identical of course.

That is very hard to describe. Normally green blue sapphires sell as teal and must be have more blue than green color in this stone. This one is blue green the stone has more green than blue color. The dichroism of green Sapphire is mostly yellowish-greem, or yellow green, rarely bluish green. From Eldorada bar i have read a few weeks ago, that they have been found which without yellow dichroism. It gives also a mermaid called sapphire that has 50% blue amd 50% green but i cant believe that it really exist an stone that has exactly the same % of both colors.
Blue green is very very often a secondary deposit found, otherwise the stone were green blue. In the past it gives not really much blue green or green sapphires, because the most sapphires are heated (for jewelry and to improve clarity) and than change to green blue or other blue tones.
From Montana the blue green sapphires has normally a very very good color and msytic glowing look because they are silky but not completly, only parts in the sapphire. When it is darker outside or rain than the stone has an very nice clear color glowing look. Color in it is
normally slightly grey/silver + blue, green and yellow from dicrhoism or inclusions. U can have pale yellow or golden yellow and on the other side from the stone icy blue or robins egg. Otherwise u can have a silvery mint green and light cyan or stronger blue and without silver. Also the stone can looks silver without coloration, when the light is strong enough. Also you can habe darker green only indoor with yellow, or if the stone is very unsaturated than u can have indoor silvery minr to. You can made 10 pictures in differen lightnings the stone will always have an other color than before.
