Diamond Education

Because the best decision you can make when it comes to buying a diamond is an informed one, we have created this guide to educate you on the four Cs of diamonds. You will learn how to understand cut, color, clarity, and carat weight of diamonds.

This easy-to-read guide will give you the tools you need to buy your quality diamond with confidence.

The cut of a diamond refers to much more than its shape. A diamond's visual beauty is a reflection of its cut, which determines its brilliance, or sparkle. A poor cut can reduce the brilliance of an otherwise perfect diamond, while a great cut can set an average diamond on fire. Sea of Diamonds exclusively carries diamonds that have been carefully cut to maximize their brilliance and we encourage you to learn about how to consider this important C as you purchase a diamond.

Color is the presence or absence of yellow tint in a diamond. When it comes to color in diamonds, less is definitely more. Colorless diamonds are the rarest and accordingly, they are priced the highest. To help you choose a diamond that appears colorless to the naked eye, Sea of Diamonds has assembled a collection of diamonds with the highest grade of color as well as this guide, designed to educate you on the color range of diamonds and how to select the diamond that is perfect for you.

The clarity of a diamond is determined by its identifying characteristics. Consider clarity as the diamond's internal thumbprint. No two are exactly alike. The impact on the diamond's quality is influenced by the size, number, location, and type of inclusion. Diamonds with very few inclusions are the most valuable as they are the rarest. Sea of Diamonds provides not only the information you need to determine the grade of clarity that is right for you, but also a wide range of stunning, clear diamonds to choose from.

Carat Weight:
While you may already know that a diamond's weight is expressed in carats, this guide is intended to inform you about the exponential rise in value of larger diamonds due to their rarity. Because purchasing a diamond requires you to consider each of the four Cs, we can help you to give the right amount of weight to the size of your diamond and chose the one that will fit your budget and look dazzling in its setting.

Carefully reviewing the grading report of a diamond is imperative to ensure that you are getting the diamond you want. This report, also known as the diamond certificate, verifies significant characteristics of a diamond, including its cut, color, clarity, and carat weight. Sea of Diamonds is pleased to educate you on the importance of this valuable document.


Although diamonds are extremely hard and resilient, care is needed to protect your investment. Learn how to keep your diamond brilliant, secure, and beautiful for a lifetime.
