    Since there’s no cost whatsoever, I’d go with the 2 ct.  Why not!  Looks great.  But realistically, IMO it’s not worth paying tens of thousands of dollars for a rock, so I’d say <1 ct if it were actually me in real life.  (My finger is size 6, my ring is 0.7 ct and I love it.)

    @IheartUFC:  I do not mean to be snarky or stupid but how is this possible?

    Notice how the difference becomes smaller and smaller as the carat size increases.

    Granted I don’t have a diamond, but here’s the mossy chart of estimated ctw size to mm width.  Diamonds are cut different I know but I would think it would be close to the same.  According to this 1/2 ctw=.25-.5mm

    I love the 2ct size!! I am a size 4, and I have a 1.75ct center stone. I just love the way it looks. I would think the 2ct on the size 6 would be comparable.

    @IheartUFC:  Hm… just curious.

    Rearding the question I like a bit big so 2 ctw= 2.5 or size 6 finger.  I have a size 5 finger and like the 2ctw look so I am bias.

    @aliciapdx:  @IheartUFC:  it’s because carat size measures volume (or maybe area?), and the mm measures width.  If you think back to high school algebra, volume (and area) increase faster than width as spheres get bigger.

    It’s the same for the moissy chart.  At the lower end, a smaller increase in carat size is equivalent to an 0.5 mm increase.  At the higher end, you have to increase carat size by a whole 0.5 to get the equivalent 0.5 mm increase.  It’s the same for diamonds (and any sphere), which is what the OP meant.

    The reason it doesn’t seem to add up is because “carat size” is a misnomer. Carat is a measure of WEIGHT not size. That’s why a 1ct stone can look like its only .75 or as big as 1.25 depending on how shallow or deeply it’s cut. The mm equivalent is taken from the size of the ideally cut stone of each shape.
