About mined 1 carat diamonds

The price difference between 1-carat mined diamonds and lab-grown diamonds can vary depending on various factors such as quality, cut, color, and clarity. In general, lab-grown diamonds tend to be more affordable compared to their natural counterparts. On average, lab-grown diamonds can cost around 50% to 60% less than mined diamonds of similar quality.

The price of a 1 carat mined diamond can fluctuate based on quality factors like color, clarity, cut, and carat weight, as well as market conditions. Additionally, whether the diamond is naturally mined or lab-grown impacts its value. On average, a 1 carat natural diamond can range in price from approximately $2,000 to $20,000 or higher. As the carat weight increases, the price tends to rise exponentially. Looking for a larger diamond? Check out our 2.5 carat diamonds and 3 carat diamonds.

The size of a 1 carat diamond can vary based on its shape, cut, and other factors. However, as a general approximation, a well-cut round diamond with a 1 carat weight typically has a diameter of around 6.4 to 6.5 millimeters. Other diamond shapes, such as princess, oval, or emerald, may have different dimensions for a 1 carat diamond. It's important to consider that carat weight refers to the diamond's mass, not its physical size, so the actual dimensions can vary depending on the specific cut and proportions of the diamond. Check our complete range of radiant cut diamonds and emerald cut diamondsalong with their dimensions and 4Cs.

Opting for a 1 carat diamond is an excellent decision. On average, engagement rings bought in the United States have a average carat weight of 0.9 carats.
