About Our Seattle Diamonds

The Cs impact the B – for Brilliance 

Diamonds are rare, treasured gems from Mother Nature to humankind. They have been gifted for centuries to captivate hearts, signify commitment and celebrate special occasions. At Fox’s, we select only the finest diamonds and partner with designers who share the same standards of excellence to provide spectacular brilliance. We are happy to share our knowledge and demonstrate the different properties that make every diamond truly unique. Some of the most special diamonds you will find at Fox's are vintage and antique diamonds from Single Stone. These sustainable diamonds were cut by hand in the late 19th and early 20th centuries, and given new life in beautiful handcrafted settings.

diamond cut


Contrary to popular belief, the cut of a diamond is not about shape (such as: round, emerald, pear, etc.). The cut of a diamond is an appraisal of how well the facets interact with light. The cut is crucial to the stone’s overall beauty and value. It is also the most complex and technically difficult to analyze. The cut of a diamond is made up of:

Brightness – the white light that reflects from the surface and inside of a diamond.

Fire – the color you see reflected from the diamond.

Scintillation – the interplay between light and dark areas of the stone that give it sparkle when it moves

diamond color


Most diamonds used in jewelry are evaluated on the absence of color. A perfect diamond has no hue, and consequently, a higher value. The color scale starts with the letter D, which is colorless, and extends to Z, with increased presence of color.

Diamonds come in many colors including yellow, pink, brown, black, green, blue and even purple and red. A fancy colored diamond uses a different color scale based on color saturation. Some diamonds emit fluorescence. This occurs when the diamond is exposed to ultraviolet radiation before it is mined. Fluorescence may not be visible unless the diamond is placed under ultraviolet light.

diamond clarity


The Gemological Institute of America uses a scale with eleven clarity grades ranging from FL (Flawless) to I3 (Included to the third degree). If a diamond has an inclusion it is not always visible to the naked eye. Clarity is graded based on the number of inclusions, their size, color and placement within the stone.

diamond carat


The weight of a diamond is measured in carats. One carat is equivalent to 100 points. It’s important to remember that a diamond’s value is determined using all 4Cs to determine its value and rarity. For example, a 1 Carat diamond can be more valuable than a 2 Carat diamond due to differences in quality on Cut, Color and/or Clarity.
