Carat for Your Thoughts?

Ring Advice

Jewelry shopping can be intimidating. That’s why we started Ask Holden, our blog where we answer your FAQs, break down scary industry lingo, and guide you in finding the perfect piece of jewelry.

At Holden, our goal is to provide you with the highest quality lab-grown diamonds. As a Climate Neutral-certified company, we’re committed to minimizing our environmental impact while crafting wedding and engagement rings that you can feel good about.

Carat, not to be confused with karat, measures the weight, and therefore size, of a diamond. A carat weighs 0.2 grams - about the heft of a paperclip. Check out the difference between the various sizes and shapes of our lab-grown diamonds in the image below.

Carat Size Diamond Shape Comparison

Keep in mind that diamonds are priced per carat, but price per carat actually increases as diamond weight increases. Not only is color more identifiable in larger diamonds, but large rough diamonds without inclusions are more rare and difficult to grow compared to their smaller counterparts.

At Holden, we offer most stone shapes from 1.0ct to 5.0ct with the option to choose the color, clarity, and cut grade of your stone. You can learn more about the differences between the 4 Cs (cut, clarity, color and carat) here.
