What Makes a Good Diamond? The 4C's



Carats measure the weight of a diamond. All else being equal, the higher the carat weight, the more valuable the diamond. 



With the exception of yellow, pink, and blue diamonds, the less color, the more expensive it is. Since carats are a measure of weight, it doesn’t necessarily reflect the dimensions of a diamond, making it extremely important that you see it in person to experience its unique shape and beauty. Not two are ever the same! 



Clarity refers to the number of inclusions and blemishes. It’s extremely rare to find a diamond without any markings, making those inclusion and blemish-free pieces the most valuable of all. 



Though most people find it hard to quantify, the Cut of a diamond has three attributes:

• Brilliance - The light the diamond reflects
• Scintillations - A diamond’s sparkle
• Fire - How light travels through a diamond

What Makes a Good Diamond? The 4C's

GIA Gradings System

The Gemological Institute of America (or GIA) is a nonprofit institute focused on gemology education and research. The institute has a number of easy-to-understand grading systems to assist in properly rating and grading diamonds.

Clarity Scale

The GIA International Diamond Grading System aims to make diamond grading more transparent and understandable. The scale ranges from flawless (FL) to diamonds with obvious inclusions (13), and is done by a skilled grader using 10x magnification. 

The complete scale:

Flawless (FL)– No visible inclusions or blemishes

Internally Flawless (IF)– Some blemishes with no visible inclusions

Very, Very Slightly Included (VVS1 and VVS2)– Some very difficult to see inclusions are present

Very Slightly Included (VS1 and VS2)– Inclusions are clearly visible, but are characterized as minor

Slightly Included (SI1 and SI2)– Inclusions are noticeable

Included (I1, I2 and I3)– Inclusions are obvious, potentially affecting transparency and brilliance


Color Scale

Much like the Grading System, the GIA Color Scale aims to make understanding a diamond's colorlessness easy so you can make an informed purchase. Starting with absolute colorlessness, the scale runs from D-Z and includes 5 tiers.

Colorlessness- D-F

Near Colorless- G-J

Faint- K-M

Very Light- N-R

Light- S-Z
