What is a 3 Carat Diamond Stone?

Understanding the 4Cs of a 3 Carat Diamond Engagement Ring 

4 Cs of a diamond are 4 grades that ensure radiance, beauty, and sparkle. Read on to understand each one of them. This will greatly help you to purchase your 3-carat diamond engagement ring.

  • Cut- It is one of the most important factors that determines how effectively your diamond handles light. The light handling capability refers to brilliance, fire, and sparkle.A poor cut quality doesn’t work with a 3-carat diamond. 

Different shapes of diamonds demand different cuts and expert know-how to maximize the brilliance. Cut simply means how it was created from coarse. If you have two diamonds with a 3-carat weight for each. The one with a fine cut will be expensive than the other. 

  • Color- It is easier to notice the color or hue present in a bigger diamond. But it doesn’t mean that you must choose a D color grade diamond for an engagement ring. Choose from G to I color grade diamonds for platinum or white gold setting. G color grade is usually looking flawless with white metals.  

If you go for lower grades like H or I, then choose a yellow gold or rose gold to set your diamond. It will help to mask the yellowish color of the diamond.

  • Clarity- Only 1% of diamonds are flawless in the whole world. No two diamonds have the same clarity grade. The lesser the inclusions, the higher the price.

As you are looking for a big diamond, you must be aware that a 3-carat stone is susceptible to imperfections due to its size. And you don’t want your fiancé to notice that.

To prevent embarrassment, choose an eye-clean diamond with VS2 or higher clarity grades. The term “Eye Clean” means the inclusions are not visible to the naked eye. 

  • Carat- The fourth C is the carat that means the weight of the diamond. As we are talking about a 3-carat stone, its weight details are already mentioned earlier in this article.
