Make sure that the light is reflected evenly out of the diamond with no dark spots. Less expensive jewelry may be more cheaply cast or stamped, leaving the marks of the mold or stamping that have to be filed off afterwards. Fine precious metals are too expensive to be used in any except the most finely made jewelry.

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 G color diamonds are next to colorless. G color may be somewhat slightly noticeable when compared to diamonds of better grades, but this grade offers excellent value. G-color diamonds are the most rare of the near-colorless diamonds. Its extremely faint tint will only be noticeable to a trained gemologist.
Clarity The stones of SI2 clarity have inclusions which are fairly easy to see under a loupe with 10X power magnification. Such inclusions may be visible to an unaided eye depending on their location. SI2 clarity diamonds of G or H color look nearly perfect when mounted. For those looking for near perfection these sure come close.
