A 1 carat lab diamond typically costs between $800 and $2,500 depending on cut, color, and clarity. A comparable mined diamond of the same quality can cost $4,000 to $8,000 or more. That gap has widened in recent years as lab diamond production has grown. Lab grown offers significantly more stone for the same budget.
