Not an enormous difference but you can see that the 1/3 carat are bigger. they are .16 or so each as opposed to .12 or .13 each and at that size you can see that much of a difference.
I gave my niece .25 ctw earrings and also gave my son a single earring of that size. .25 is a nice size. You can definitely see it and both of their earrings look nice, even though not ideal cut or even especially white (maybe J color I think? Set in yellow gold).
I own a pair of .10 ctw and on my particular ears you can't see those especially well. They are also something like I2's and don't have much sparkle. But they are in a pretty buttercup setting and I wear them as a second earring a lot of the time. they are a sentimental gift from my husband.
Normally (without the buttercup setting) .10 ctw is so small that my son complained that he felt that the diamond was about to go backwards through his ear hole . with Tiffanys, the bezel may help with this issue? Also, they are probably a good color and a great cut.
Whiteflash should be awesome if you get their ACA's in melee--I have large whiteflash earrings and it is amazing how much they sparkle. Even in rotten lighting conditions. When my other diamonds aren't sparkling, those babies still sparkle and I think that really small earrings (I don't count .25's as really small) would be awesome from them (although not cheap. I'd hate to tell you what I paid for my 1.81 ctw--my bigger pair.)
