About Lab Grown Diamonds
Lab grown diamonds are created using two technologies that recreate the extreme heat and pressure found beneath the earth’s surface: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both begin with a tiny diamond seed and build a full crystal atom by atom, producing a stone with the identical crystal structure as a mined diamond.
Because the only difference is origin, lab grown diamonds are graded on the same 4Cs by the same independent laboratories. The result is a larger, higher-quality diamond for your budget, with no compromise on beauty or durability.
Lab Grown Diamond FAQs
Are lab grown diamonds real diamonds?
Yes. A lab grown diamond is a genuine diamond with the same chemical, physical, and optical properties as a mined one. The only difference is origin: it is created in a laboratory rather than extracted from the earth, and it is not a simulant like cubic zirconia or moissanite.
How are lab grown diamonds made?
Two methods recreate the conditions that form natural diamonds: HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). Both start with a tiny diamond seed and grow a full crystal over a few weeks.
Are lab grown diamonds cheaper than natural diamonds?
Typically 40-70% less than a mined diamond of equivalent carat, color, clarity, and cut, so you can choose a larger or higher-quality stone for the same budget.
Will a lab grown diamond pass a diamond tester?
Yes. Because it is the same material as a mined diamond, it reads as diamond on a standard tester. Specialized lab equipment is needed to distinguish lab grown from mined, which is why every certified stone is laser-inscribed with its report number.
Are Diyona lab grown diamonds certified?
Every Diyona lab grown diamond is independently graded and certified by IGI or GIA, the same laboratories that grade natural diamonds, with the full 4Cs, measurements, and origin on the report.
Are lab grown diamonds conflict-free?
Because they are created in a controlled laboratory, lab grown diamonds involve no mining and their origin is fully traceable. Many shoppers choose lab grown for that transparency.
Will a lab grown diamond last?
Diamonds are the hardest known material, a 10 on the Mohs scale, lab grown included. With normal care it lasts generations and never clouds or fades.
How fast does Diyona ship?
In-stock lab grown diamonds ship free within 2-5 business days, fully insured, and are backed by a lifetime warranty with free returns.
