1. Are synthetic diamonds the same as lab-grown diamonds?
Yes. Lab-grown diamonds can also be called synthetic diamonds, artificial diamonds, and cultivated diamonds. That being said, lab-grown diamonds are a more professional name.
2. How do you grow diamonds?
There are currently two methods for growing diamonds: high pressure and high temperature (HPHT) and chemical vapor deposition (CVD). Each process works best for diamonds of a particular size and color.
3. Where are lab-grown diamonds produced? How long does it take to grow diamonds?
Scientists, engineers, and technicians all over the world grow diamonds in high-tech facilities. This is where important diamond production takes place: in the United States, Belgium, Russia, India, China, and Singapore, among others.
It takes 7-10 days to grow a 1-carat rough laboratory diamond, and about a month to grow a 3-carat diamond. If you try to grow a diamond faster, the crystal will break. Therefore, there is a physical speed limit to how fast diamonds can grow.
4. Is lab-grown diamonds cheaper than mined ones?
Yes. Lab-made diamonds tend to have a lower retail price than natural diamonds of the same quality. Lab-grown diamonds are priced according to their quality, just like mined diamonds. We are often asked how much is a 1-carat lab-grown diamond. The answer is that it depends on the quality, just like mined diamonds.
5. Are laboratory diamonds graded by a third party?
Yes. Almost all lab-grown diamonds are graded and certified by a reputable professional gemstone identification laboratory such as GIA, IGI or NGTC. We provide grading reports of any diamond to our customers and can verify these reports by looking for ids on the website.
6. Do lab-grown diamonds change color over time?
No. Lab-made diamonds do not fade, discolor or become cloudy over time.
