More Options
A lab grown diamond is one that has been manufactured in a controlled laboratory environment. Using the popular methods of Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT), scientists can now create diamonds that optically look like earth-mined diamonds, contain the same chemical and physical attributes and even receive certification through the Gemological Institute of America (GIA).
Natural diamonds are created under the pressure of earth's crust over millions of years, then they are mined, cut and polished. A Lab Grown Diamond is placed through the same circumstances, only in a lab setting. In fact, the process used to create a Lab Grown Diamond cuts down the grow time significantly, from millions of years to a couple of months. Then, the Lab Diamond is also cut and polished.
2：Are Lab Diamonds Real?
YES. Lab Grown Diamonds are just as real as diamonds that are mined from the earth. They have shape, size, color and clarity grades, just like Natural Diamonds. Both Natural and Lab Grown Diamonds have the same physical and chemical properties and both come with diamond certifications.
3：Lab Diamonds vs. "Real" Diamonds - What are the Differences?
The differences between Natural Diamonds and Lab Grown Diamonds cannot be seen with the naked eye. Natural Diamonds have tiny amounts of nitrogen, while Lab Grown Diamonds have no nitrogen. This is actually one of the signifiers gemologists use to identify if a diamond is lab grown or natural.

4：Are Lab Grown Diamonds Good?
Generally speaking, the answer is Yes. A perfectly cut, internally flawless diamond is quite expensive and rare whether it is a Lab Grown Diamond or a Natural Diamond. Lab Grown Diamonds and Natural Diamonds exhibit varying amounts of internal "inclusions" likened to fingerprints and are referenced and graded accordingly by accredited gemological labs. Lower clarity graded Lab Grown or Natural Diamonds may have inclusions that can be seen by the
"naked eye". The cut & color is also very important in determining whether a diamond is excellent, very good, good, or poor.
