Benefits of a 1ct diamond

If you were to ask 1000 people what the best centre stone size for an engagement ring, the majority would likely respond with the 1ct Diamond. At the same time, for most people, the higher the number of carats, the better. But this also comes with a price, as diamonds increase in price exponentially with the increase in carat weight. So, just go find the balance between the beauty and the price of a diamond. We hope this guide to 1ct Diamonds will be really helpful and help you make the best purchase. If you want to know more, go to our article: how to choose a diamond.

How big is a 1-carat diamond?

Not all 1 carat diamonds are the same size. So, we will help you understand how different diamond shapes at the same carat weight compare.

A 1-carat Round diamond should measure around 6.5 mm.
Pear and oval-shaped diamonds are wider and more flat.
Round and Asscher cuts tend to run deeper.

If you’re looking for the most carat for your money, look no further than a Marquise. This flat, generous diamond shape not only elongates the finger but looks nearly twice as big as round.

Settings for our range of 1 ct diamonds

The whole carat diamond is the ultimate classic and the most popular size for all rings settings, from simple solitaire to the chic halo. As for the colour of the setting, a white metal band can act like a mirror to reflect and amplify the diamond’s size. Rose gold or yellow gold band could serve as a dramatic counterpoint to the diamond, making it look bigger.
