Diamond Grading
Can a casual observer tell anything about the value/quality of a diamond ring just from seeing it on your hand

Other than the size of the diamond, can an experienced or knowledgable observer "tell" if a diamond is of high quality, top-notch cut/color/clarity, or a cheap lower grade diamond. I mean by casual looking, not examining with loops or anything. Could anyone even tell the difference between a diamond and a CZ just by a quick glance?

Yeah you could, if you could tell the signs of the difference of the colors, the shine and also the style and the look of the loop or ring
