Spotting the best of 3 diamonds, help appreciated

[thrill_of_the_hill]

another one taken just now with same lighting - its often white but sometimes looks grey

under slightly brighter light its white again

My diamond is also a whiteflash ACA, I color, VS2 (but much smaller than yours at 1.84 ct)

Mine similarly goes gray in sunlight/bright light. It sparkles like the dickens in ambient light, spotlights, Costco lights are the best!

I found this post to explain what is happening. I'll be honest, I don't understand all the optical terms, but I found comfort in it

Thanks for the link, Ive just read it and see a few people have this "problem" - it appears to be more noticeable with ideal cut diamonds (mine is also a Whiteflash ACA)
Does it bother you? Is it something given the choice you would return and exchange? The experts I showed said to return it, as they said it is white from the sides and upside down yet grey on the top even in the same lighting. Should I try another expert appraiser?

It doesn't bother me, but mine doesn't seem as extreme as yours (and maybe this is because of the smaller stone size).

I figured that because it is such a fireball in most lighting settings (probably 98% of where I spend my time), I would rather have that than something that sparkles better in direct sunlight but looks dark indoors

An ideal cut stone generally goes dark to the eye in bright lighting. Diamond color is diamond color and they are colored graded in a face down position. There are tint variables too shouldn't be a concern with an ACA diamond. I think you are seeing something that is quite normal in terms of darkness. Diamonds only reflect back the amount and type of lighting they are viewed in.

You are experiencing an optical phenomenon, this has nothing to do with I colour, it would happen with a D colour stone. AGS isn't as known in the UK but you are receiving wrong advice and I find it hard to believe these so called experts are blaming bad grading for what is quite obviously nothing to do with body colour of the diamond. It's well known that ideal cut stones can take on a darker body in direct sunlight. Also dirt and fingerprints are much more problematic in certain lights so clean your diamond. You have the pinnacle of well cut stones which excel in ambient lighting. Being in the UK, bright sun isn't too much trouble for you...(apart from this last week)
