For every woman, a diamond engagement ring is a valuable piece of jewelry. It represents love and devotion, so it is necessary to go for rings perfect in shape and size, and 1-carat engagement rings have become a go-to choice.


It is significant to bear in mind that a carat is a weight measurement and not the size of a diamond.  A 1-carat diamond measures from 6.11mm to 6. 53mm.


This variety happens due to the shape of a diamond and the way it’s cut. Some diamonds cut more deeply, causing the weight to conceal in the bottom of a diamond. A 1.5-carat diamond is a size in between a 1ct and 2ct diamond with a size that is visually larger.

The table below shows that diamonds of the same carat can vary in size, so they’re smaller than round diamonds.

To get the accurate size measurement of a diamond: it is best to use a jeweler’s scale. A 1 Carat Diamond Ring is ideal for engagement rings, but only for distinct shapes.


Cut grades are very significant in the size of a one-carat diamond and can even make a small diamond appear large.  For example, if a finger’s average width is 17mm, a 1ct diamond ring will cover around 38.2% of the finger’s width.


A 1 Carat Diamond Ring is sizable enough to be noticed on a finger and a substantial start for those looking to buy significant diamond rings.

What Setting is Best for a 1 Carat Diamond Ring?

Let’s dive into these.

Any style will look great on a 1-carat ring. A 1-carat solitaire diamond ring may look big in that setting, but for a 1 Carat Diamond Ring to be substantial, a halo setting is best. Smaller diamonds surround the center stone, maximizing sparkle and size.


This setting type for a 1 Carat Diamond Ring is a unique touch of class and elegance. There are single and double halos, both of which are an excellent blend of trendy design, impeccable technology, the masterpiece skills of knowledgeable jewelers, and the grace that results from the combination of antique and modern fashion.


The extra shine provided by the smaller stones in a halo setting visually broadens the size of a 1 Carat Diamond Ring.

The two types of halo settings are:


  • Single halos settings feature smaller stones firmly wrapping the center diamond and often making it appear as an illusion of a large diamond. 


  • Double halo settings have two halos encircling a center stone, making a 1 Carat Diamond Ring appear large and creating more sparkle and protection.
