What if you could own one of the world’s most costly diamonds?

Well, you can! That is if you have millions and millions of dollars. We are your local Austin diamond buyers and before we reveal the jaw-dropping figures, let’s first discuss what determines the cost of a diamond.

How To Examine A Diamond Like A Pro

First things first

There are 4 major factors to determine how much a diamond is worth, know as the 4C’s of diamond grading.

# 1 The Cut

Simply put, this refers to the shape of the diamond as well as the proportions, symmetry and polish.

# 2 Clarity

There are 11 Grades to determine your diamonds clarity. The fewer inclusions, or blemishes in a stone, the better the clarity grade.

# 3 Color

This refers to diamonds that lie within the color range, not “fancy” color diamonds that are blue or red. Actually, the less color, the more valuable the stone is.

# 4 Carat

As most people already know, this is a way to measure the size of a diamond.

You can learn more about the 4C’s from the Gemological Institute of America (GIA)
