The price difference between lab-grown diamonds and earth-mined diamonds can vary depending on a number of factors, including the size, colour, clarity, and cut of the diamond. However, as a general rule of thumb, lab-grown diamonds are typically 20-30% less expensive than earth-mined diamonds of the same size, colour, clarity, and cut.
For example, a 1-carat, colourless, VVS1 clarity, round brilliant lab-grown diamond can cost around \$2,000 to \$3,000. A 1-carat, colourless, VVS1 clarity, round brilliant earth-mined diamond can cost around \$3,000 to \$4,000.
The price of lab-grown diamonds is expected to continue to decrease in the coming years, as the technology for growing diamonds in a lab improves and the demand for lab-grown diamonds increases. This is good news for consumers who are looking for an affordable and ethical alternative to earth-mined diamonds.
