A great carat standard for a diamond ring is 1 carat. It allows room for the diamond to be as brilliant and fiery as it can, while also maintaining a grandiose aesthetic for the eye. While 1 carat diamonds all weigh the same, it’s important to look at several features of the diamond to make sure you are getting the best bang for your buck. A carat is a measuring unit jewelers use to identify how heavy the diamond is. Carats are 1 out of the 4 C’s of Diamonds.

Pricing the Diamond Carat:
Diamonds are all priced according to their carat weight. An example of how a Diamond is priced: a diamond weighing at 0.5 carats would be worth $750 if each carat was worth $1,500 per Carat. Diamonds aren’t just only priced based on the carat weight, however. They are also priced based on a variety of factors from different reports and other diamond features.

Diamond Carat vs. Size
These two are confused very often and are actually two completely different things.
The Diamond Carat refers to the actual weight of the diamond, while the Diamond’s Size deals with the visual appearance of the diamond. A higher carat doesn’t always mean that it will look bigger and a bigger size doesn’t exactly mean that the diamond will be heavier. All diamonds are cut and formed differently.
It is extremely important to consider many components like how the surface area and depth of the diamond affects the way the diamond looks in terms of brilliance, reflections, and shape.
How to Find the Best Valued 1 Carat Diamond:
The goal of purchasing a diamond is to get the best quality diamond without being overcharged.
The first thing to look at is the certification. GIA and AGS Certification is one of the greatest factors in the pricing.
Next, you’ll want to look at the following features of the diamond:
- Cut: Try to find a cut with an Excellent Grade to maximize brilliance. Cut is extremely important for bringing out the diamond’s reflective qualities and widely known look.
- Color: Colorless diamonds are probably your best bet. Colorless diamonds put out more emphasis on the fiery and brilliant look of the diamond.
- Clarity: Clarity grades of VS1 and VS2 are the preferred grade. This grade would help hide and inclusions or flaws in the diamond.
- Shape: 1 Carat diamonds can come in many sizes. You can pick any shape you want that fits your preference and taste.
- Reputation: When you buy a diamond from a reputable company, you can ensure that you’re buying at high quality and a fair price. The companies we recommend are Blue Nile, James Allen, and White Flash.
