The 4 C’s to Buying Diamonds

Diamonds may be a girl’s best friend, but guys consider them the enemy because guys don’t know much about them. Knowing about the 4 C’s when buying a diamond can help you with another C (and it’s an important one): Cost.

Make sure you understand the 4 C’s to a diamond. Visit to learn all about them.

Cut Diamond buyers often mistake cut for shape–a diamond’s cut refers to its reflective quality, and the perfect cut will reflect light up through the center of the stone. Have you wondered why some rings sparkle and others don’t? This is why. If you’re looking for a ring that sparkles the most, cut will be very important to you. You should get a diamond cut grade of Good or better in order to have your ring reflect majority of the light that enters it.

Color- A colorless diamond is the rarest and most valuable diamond, so the more color a diamond has, the less rare it is. The color system ranges from D (the highest grade and colorless) to Z, which means the diamonds have a light yellow color. Unlike school, grades D, E, and F are the best and most valuable. The differences between these three grades can’t be detected by the untrained eye, so if you’re looking to save but still want the highest color, a diamond with an F on the color scale is perfect. If you’re looking for a great value, any diamond with a G, H, I, or J grade (near colorless) will be great for you–because they have traces of color, setting them in a white gold or platinum setting will offset the color of the diamond. Additionally, if a warm color appeals to your loved one, you can spend half the money buying a K diamond than you would on a G one.

Clarity– A blemish on your skin makes you freak out, but diamonds naturally contain blemishes (or inclusions), though most cannot be seen by the naked eye. Therefore, a diamond without any blemishes is considered rare, which means it is very valuable. An internally flawless diamond has no blemishes that can be detected by the naked eye. If you’re looking for the best value, a diamond with very very small inclusions (VVS) or very small inclusions (VS) will give you a gorgeous diamond with a small blemish or two. Then again, don’t we all have a small blemish or two?

Carat– Often mistook for size, carat is the weight of the diamond. Diamond carats range from .25ct (which is 4.1 mm), .50ct, .75ct, 1ct, 1.25ct, 1.50ct, 1.75ct, 2+ct. For those who want the best value, getting a lower carat diamond with a higher cut will make the ring sparkle. After all, size doesn’t matter, right?
