Explore The 4 Cs of Diamonds

People often confuse a diamond's cut with its shape. Diamonds are cut into a variety of shapes depending on the nature of the rough stone. The most popular cuts are round, marquise, oval, pear, heart, and emerald. The one right for you is largely a matter of personal preference.

No matter the shape, however, a well-cut diamond is the work of a master diamond cutter. When a diamond is cut to good proportions, the diamond is able to handle light better, creating more scintillation, more sparkle, and making it look even more fantastic on you!

Diamonds come in a wide range of colors, from faint yellow to brown to very rare pinks, blues, greens, and other colors known as "fancies." The best color for a diamond is no color at all. Totally colorless diamonds allow white light to pass through effortlessly, and the light disperses as rainbows of color, creating an incredibly beautiful effect.

To determine a diamond's clarity, we view it under 10-power magnification with a trained eye. Most diamonds contain very tiny natural inclusions. The fewer and smaller the inclusions are, the less likely it is that they'll interfere with the passage of light through the diamond. More than any other gemstone, diamonds have the capability to produce a maximum amount of brilliance.

A diamond with no interior or exterior inclusions is very rare and, therefore, more valuable than those that do. The clearer the diamond, the clearer your choice!

A diamond's carat-weight is quite simply the weight of the diamond measured in carats. One carat is divided into 100 "points" so that a diamond of 75 points weighs 0.75 carats. Carat-weight is the easiest of the 4 Cs to determine. Two diamonds of equal weight can have unequal value depending on their cut, color, and clarity.

Fine quality can be found in diamonds of all shapes and sizes.

"My fiancé and I dealt with Center Gold for an engagement ring and we were more than happy with the results. The ring came out beautiful and had everything I was looking for. The staff was beyond helpful and worked with my fiancé every step of the way. Renee went above and beyond to make sure everything was perfect. Even two months after being engaged, she still is there to answer any questions or concerns. Very professional place, will definitely be back for our wedding bands. Thank you, Center Gold!"
