Buying a diamond? What do you need to know to be a savvy diamond shopper? It all starts with what is called the “4 Cs” of diamonds. Master the 4 Cs and you’ll be well on your way to choosing the best diamond for your budget.
This article refers to GIA throughout. GIA stands for the Gemological Institute of America. GIA is a nonprofit institution committed to protecting and educating the public in the field of gems and jewelry. GIA created the 4 Cs to describe the characteristics of a diamond and is an excellent resource to consumers.
Diamond cut refers to the way a diamond is faceted and the way those facets reflect light, not the shape of the stone (round, princess, emerald, etc.) Cut is an important characteristic to consider when choosing a diamond and has the most impact on a diamond’s sparkle. A well-cut diamond will have more fire, brilliance, and will generally look larger. A poorly cut diamond will look, well, pretty much the opposite.
Diamond cut is measured on a 5 range scale from excellent to poor.

Diamond color is measured on a scare from D-Z, and actually measures the lack of color in a diamond.
Colorless Diamonds - The Rarest, Highest Quality,
Near Colorless Diamonds - No discernable color. Better Value.
Faint Color Diamonds - Budget-friendly. Looks great set in yellow gold.
Pro Tip: Color will be more visible in larger diamonds. Settings can also impact color. A white gold setting will make a diamond with more color look more yellow, or a colorless diamond look icier. A diamond with more color will often look better in a yellow gold setting.

Clarity measures the presence or absence of inclusions in the diamond. Inclusions are small imperfections in the diamond kind of like birthmarks. There are many different types of inclusions, but the good news is that most aren't visible to the naked eye.
Pro Tip: Very slightly included and very very slightly included diamonds are often the best value, and inclusions in this range are almost always only seen under 10x magnification.

Diamonds are measured by their weight, not the physical size of their dimensions, and a diamond's carat weight has the biggest effect on price. That being said, bigger is not always better when it comes to diamonds. A diamond's shape and cut play a big part in how large a diamond will look.
Pro Tips: Buy "shy." A 1.90 carat diamond will cost considerably less than a 2.00 carat diamond, and the size difference will be barely noticeable. Also, keep the ring size in mind when choosing a diamond. A diamond is going to look larger on a ring size 6 than a size 8.

Limitations of the 4 Cs
Like snowflakes, each diamond is 100% unique. Because each diamond is unique, two diamonds that are graded the exact same will look slightly different. This is where buying a diamond in person becomes important. Being able to compare two or more similar diamonds can be an invaluable step in choosing the perfect diamond for your taste and budget.
This is one of the biggest downsides to buying a diamond online, and the biggest upsides to buying in person.
