Retail jewelers will carry a small to medium selection of diamond earrings, but you will find a greater selection online. All you can do is make sure the backs are good ones and they work well and that means on both earrings. Try putting both earrings on and taking them off several times.

Explanation of Cut, Color and Clarity of This Diamond
Cut Quality The ideal cut diamond is a very precise mathematical equation, where diamond proportions and angles are cut to optimize the diamond's superlative optical properties, in particular it's high refractive index and color dispersion, to create a diamond of unequaled beauty with perfect balance of brilliance and fire. In layman's terms, the diamond is cut to make it the most beautiful diamond so it retains its intrinsic value.
Color An E color diamond is extremely rare and slightly less expensive than a D but is so similar that most people won’t be able to tell the difference. You pay a serious premium for an E color diamond. Diamonds of this color grade will appear colorless even when observed face down.
Clarity IF clarity diamonds are internally flawless. diamonds of IF clarity exhibit no inclusions and may have insignificant blemishes that are extraordinarily difficult to see even under high magnification. Diamonds of this grade of clarity are extremely rare and expansive.
