Buying Tips

Buying Tips

  • Cut is the most important of the 4Cs because it has the greatest influence on a diamond's sparkle.

  • Even if a diamond has a perfect clarity and color grade, if it has a poor cut, it may appear dull.

  • When diamond cuts are made with the proper proportions, light is returned out of the top of the diamond (which gemologists refer to as the table). If the cuts are too shallow, light leaks out of the bottom; too deep and it escapes out of the side.

  • To maximize your budget, choose the highest diamond cut grade your budget allows. We suggest a cut grade of Very Good or better.
