A diamond's shape refers to its form, which is largely dependent on the shape of the rough crystal from which our cutters begin. The Round Brilliant shape is the most popular, comprising approximately 80% of all diamonds. All other shapes are collectively referred to as fancies.
Cut or make is the term commonly used to refer to the quality and professionalism of a diamond's craftsmanship. Cut is an extremely important characteristic in determining the overall beauty of the diamond. For this reason we only select the highest cut grades available.
Every diamond is carefully inspected by experienced experts for its outstanding cut.
- Shallow Cut
- Excellent Cut
- Heavy Cut
Color is graded on the lack of color present in a diamond. Color found in diamonds presents itself as varying hues of yellow and brown. The less color present in a diamond, the higher the color grade. Color grades range from D-Z with D being colorless or the highest grade.
Online we only offer diamonds with color grades from D to K. We also recommend the color combinations that work best for each specific setting.
Clarity refers to the number and size of small imperfections naturally found in nearly all diamonds. These imperfections, often referred to as inclusions, determine a diamond's clarity grade. The more frequent and greater the size of inclusion the lower the clarity grade.
Clarity grades range from FL-I3. We only offer GIA® certified diamonds from IF to SI2. Along with color guidance, we recommend the clarity combinations specific to each setting.
- I2 - I1
- SI2 - SI1
- VS2 - VS1
- VVS2 - VVS1
- IF - FL
Carat is a measure of a diamond's weight. A carat is one fifth of a gram. The larger the carat weight, the more rare and valuable the diamond. A diamond's physical appearance is not only influenced by its carat weight, but the quality of its craftsmanship also has a significant impact. Properly proportioned diamonds will look larger and more beautiful than most poorly cut diamonds.
The diamonds we use in our settings are F-H color and SI1-2 clarity exclusively, unless specifically noted. Every GIA® certified diamond offered for sale is certified to exhibit no or at the most, medium fluorescence.
The certified round brilliant cut diamonds offered for sale in this collection have been certified as exhibiting either "excellent" or as a minimum "very good" cut, polish and symmetry the two highest grades offered by GIA®. In the case of fancy cut diamonds our collection also includes diamonds certified as "good" polish and symmetry. Presently GIA® does not offer cut grades for fancy cut diamonds.
Every certified diamond offered for sale in this collection has been hallmarked. Our hallmark is registered with the United States Patent & Trademark Office and provides the purchaser with a lifetime warranty and guarantee that their diamond is natural, untreated and purchased from legitimate sources not involved in funding conflict and in compliance with United Nations resolutions.
Each GIA® certified diamond has also been inscribed with a registered serial number. This added security will greatly simplify identification of your diamond and will conclusively establish your title and ownership if required.
