Diamond Cut For Engagement Ring

When considering a diamond engagement ring, you’ve probably deliberated heavily over the shape – referred to as the cut by many, although this is actually the way in which the diamond is finished and how it reflects light. According to our recent research, the classic solitaire diamond is the most popular shape for many people in 2017 so far, with 51% of people purchasing this traditional style for their engagement rings!

Let’s take a closer look at diamond shapes and the features of each one, which might help when making that all important purchase:

Classic solitaire: Also referred to as a round brilliant, this classic diamond shape is loved by many and is ideal for those who want an easy to wear piece of jewelry that still sparkles beautifully. Round diamonds never go out of fashion, so you can’t really go wrong.

Heart: Best reserved for those true romantics who want a statement piece of jewelry, heart shaped diamonds are pretty but most commonly seen in pendants and bracelets rather than engagement rings. Although, Lady Gaga did famously have one during her engagement to Taylor Kinney so the style could see a resurgence in popularity.

What are considered the best diamond cuts for engagement rings?

A diamond cut is what determines its grading and therefore the price it is sold for. When cutting a diamond, the idea is to cut it to ensure the most amount of light is reflected. There are three types of cuts: shallow, ideal and deep.

A shallow cut is one of the least sought after as the light is not reflected and simply passes through the diamond. A deep cut is similar but a little light is sometimes reflected back up. An ideal cut is when light enters the diamond and is reflected back up. These all determine how the diamond sparkles in the light and is one of the biggest factors when people are choosing their engagement rings. 


Diamond cuts are graded in five types:

·      Ideal or excellent cut – This diamond reflects almost all the light that enters it.

·      Very good – This diamond reflects a large amount of light but is lower in price.

·      Good – This is the most affordable option but the diamond still offers plenty of sparkle.

·      Fair – This diamond reflects a small amount of light but is one of the most affordable.

·      Poor – This diamond cut will come with a very low price tag but won’t sparkle as brilliantly as others.
