I have an ideal cut diamond and it turns steel grey too.  I had a F1 moissanite when my husband and I first started looking at rings and stones and noticed it too took on a grey appearance in the sun, but it was much less crisp and almost milky in appearance.  My husband didn’t care for the moissanite at all so I returned it.

I think it’s completely normal.

I think both diamonds and moissys do this. I have a very “moody” stone… And mine is almost always steely grey, and sometimes it look grayish blue. Its actually what I like about my stone.

How interesting! I haven’t experienced this with my diamond yet (but I’ve only had it for a little while). Curious though

I have a sapphire and it does the same thing. It’s this fantastic brilliant blue in clouds, but steely grey in direct sunlight.

I have an F1 H&A and while she is white most of the time she does take on a steel gray on occasion!

What I’m about to say might be dumb. I have no idea how white moissanites are made, but I know that diamonds with strong blue fluroescence will turn gray in the sun.

Maybe they use some sort if blue “something” to balance out the yellowness of the moissanite? And that shows in the sun? I have an untreated moissanite and it it’s kinda yellow and dull on cloudy days and very sparkly on sunny days.

My current diamond doesn’t turn gray in the sun, but one of my old ones did. I think it just has to do with the way they’re cut. Mine is super sparkly in indoor light, indirect light, cloudy days and dim light. But in direct sunlight I just see all the facets and it’s more white/black if that makes sense?

My diamond doesn’t turn gray in the sunlight, if anything it sparkles more

I’ve seen this happen with *all* kinds of stones.. diamonds and moissanite.  But specificall off brand moissanites, not so much the c&c’s.  And I’ve never owned the F1, just the FB.  Beautiful ring though 🙂

My morganite does this too. In fact, I prefer when it looks steely gray lol.

My 7mm FB can look grey in my car on cloudy days (outside, it looks white):

This is about as much sun as I’ve seen in the last 2 weeks:

Inside at home by the window:

Starbucks lighting lol:

Harsh tungsten lighting can make it look grey, but it seems to depend on the angle at which it enters the moissanite and how intensely. *shrug* 😕
