Diamonds are the world's most exquisite gemstones; the hardest transparent substance known to man. Diamonds have been revered and sought after for thousands of years. Their ability to reflect light and create an explosion of sparkle and fire ignited imaginations and passions all over the world. When purchasing a diamond; the 4Cs; Cut, Color, Clarity, and Carat are important to consider. It is a combination of the 4Cs that determine a diamond's beauty and value. Learn more about the 4C's and our frequently ask questions.

The Four C's About a Diamonds Beauty and Value

The cut of a diamond is vital to release the fire and brilliance of the stone and as a result, cut is regarded as an important component of the 4Cs. When a diamond is cut to specific proportions, light will reflect from one facet to another and disperse through the top of the stone resulting in a display of fire and brilliance. Diamonds that are cut too deep or too shallow lose light as it spills through the sides or bottom of the stone resulting in a dull and less brilliant appearance. Diamonds come in a variety of shapes and new variations are being designed as alternatives to more conventional shapes.
Diamonds range in color from colorless to near colorless, to yellow or brownish yellow. The most valuable and highest quality diamonds have no color in them. Color is rated on a scale that ranges from D-Z. (D-F) Colorless, (G-J) Near Colorless, (K-M) Faint Yellow, (N-R) Very Light Yellow, (Q-Z) Yellow, and (Z+) Fancy Yellow.
Every diamond has natural markings. These markings are referred to inclusions. Often invisible to the unaided eye but when viewed under a jeweler’s loupe or microscope at 10X magnification, these inclusions may or may not be visible. The fewer and smaller the inclusions, the more valuable the diamond becomes. IF- internally flawless, no natural characteristics visible under 10x magnification. Extremely rare. VVS1-VVS2- very very slight- minute characteristics, extremely hard to see under 10x magnification. VS1-VS2- very slight- very minor characteristics. Difficult to see even under 10x magnification. SI1-SI2-slightly included- slight characteristics that can be seen under 10x magnification. I1-I2- included- characteristics are visible to the naked eye.

Diamond FAQs

A: A diamond is a mineral composed essentially of carbon that has crystallized at extremely high temperatures and pressures. In nature diamonds form 93-124 miles or more below the earths surface. Diamond is the hardest of all known natural substances (10 on the hardness scale)
A: Most consumers who make purchases of significant value come with important certified documentation. Houses have deeds, vehicles have titles and registration, but what about something as important as a diamond? A diamond grading report isn’t an appraisal but a scientific blueprint of your stone’s exact qualities. GIA’s heritage as a research and educational institution means they are trusted to provide accurate, unbiased diamond evaluations. A diamond grading report or GIA Certification provides an expert analysis of a diamond's quality based upon the 4C’s of a diamond grading. The GIA diamond grading report also contains a plotting diagram that clearly shows the diamonds unique inclusions and other clarity characteristics. It undergoes a technical screening process, determining it’s potential as a synthetic or simulated, and also to ensure that the color is natural. Another Valuable Certification is AGS.
A: Certain diamonds emit a subtle blue glow when exposed to ultraviolet rays. Many light sources including the sun, fluorescent office lights, and “black” lights emit ultraviolet rays. In normal lighting conditions, fluorescence cannot be seen. In a few cases, diamonds with very strong fluorescence may look slightly “cloudy”.
