Before You Buy

Remember, no other factor has a greater effect on a diamond’s appearance—so choose the highest cut grade you can afford. We recommend an Ideal, Excellent, Very Good, or Good cut so that you are acquiring a diamond that is in the top 25% of all diamonds.

The 4 C’s


To learn everything you need to know about buying diamonds, keep your focus on the 4C’s: cut, clarity, color, and carat weight. Each of the 4C’s affects a diamond’s appearance and influences its price.

The Fifth C: Confidence


We offer certification from the foremost gemological laboratories—GIA, GCAL, EGL, IGI, and AGS. You have the confidence of knowing that their appraisal of cut, color, clarity, and carat weight are recognized throughout the world. To further protect your investment, many of the diamonds are laser inscribed with the certificate number for identification purposes.

Shape


Every love takes shape in a different way—and forms under different conditions. The same is true for the many interesting shapes that can emerge from a rough diamond in the hands of a master cutter. Each shape has a style of its own that best displays the reflective attributes of a diamond.
