Here's a perfectly pure, Natural Earth Mined Light Gray Diamond.
As you can see, blue and gray are related. Not that his is, in any way, a blue diamond.
Still....there's something very cool any steely about this stone. .
And it does this while really sparkling and even flashes of fire..
To me, the diamond is eye clean.
Of ocurse, my eye s ain't what they used to be:).
Still- the clarity is just not an issue here.
