I am thinking of getting this ring, ( I am new) I havent seen it in person, I am curious because I was sent several photos, most of them the stone looks pretty white, but in this one, which looks like it was taken outside in natural light, looks blue and brown to me? It is graded as k color... wondering if the blue/brown i am seeing is a sign of bad coloring, (i have read that k is a 'slight yellow' but thats not what i see here) or it will just change depending on the lighting, or if anyone has seen a stone with this coloring? thanks!
