About
Natural diamonds are formed over billions of years deep below the earth's surface, under extreme pressure and high temperature. They rise and become accessible by volcanic eruption.
Lab-created diamonds are produced in a lab within weeks or months, using specialized technology that mimics the extreme heat and pressure of a natural diamond's growing environment.
For a side-by-side comparison, see our Natural Diamonds vs. Lab-Created Diamonds article.
Value
Neither is inherently higher quality, as both lab-created and natural diamonds are available in a range of color, cut, clarity, and carat weights.
A natural diamond has historically maintained its value. However, since lab-created diamonds are relatively new, it is unknown if they will retain their long-term value.
Just as with natural diamonds, lab-grown diamonds are available in a wide range of price points. Whether natural or lab-grown, the value of a diamond depends on the 4 Cs: Cut, Color, Clarity, and Carat Weight. However, lab-grown diamonds are generally viewed as the more budget-friendly option, as they typically offer more size for the same cost.
Yes. Just like a natural diamond, a lab-created diamond can be insured. Generally speaking, the application process, policy terms, and proportional costs are identical to what you would expect for a natural diamond.
