This process doesn’t have to be stressful; it is a creative and touching way of expressing your love. Learning what to look for in a diamond will help you evaluate its quality, and therefore, its value and price. You may have heard of the four Cs – but what exactly are they?


The cut is often considered the most important characteristic to consider when buying a diamond because it will determine a diamond’s sparkle. This isn’t the same thing as the diamond shape. Cut is the diamond’s arrangement of its facets and quality of craftsmanship. The cutter’s work will determine the overall appearance of the diamond. The grades range from “excellent” to “poor.”

The vast majority of diamonds have inclusions due to their creation process. This can create unique characteristics, both externally and internally, that aren’t always visible to the naked eye. The fewer inclusions there are, the higher the clarity grade. The GIA established a diamond grading system and clarity scale to allow you to navigate your way through the world of diamonds. These terms are universal. The clarity scale ranges from internally flawless to included, and we would be happy to explain the differences between them.

Another important detail when you are buying a diamond is the color. The diamond color scale ranges from D-Z. D is considered colorless, and diamonds get increasingly yellow the further you go down the scale. Additionally, for those not looking for a white stone, colored diamonds are called “fancy diamonds” and can be anything from yellow to pink.

Carat Weight

Lastly, the carat weight is another key feature of your diamond. Size can also reflect the stone’s rarity as large stones are scarcer. If all other factors are equal, the higher the carat weight, the more expensive the stone is.
