Are Man-made, Synthetic, or Lab Grown Diamonds Real?
Yes. Laboratory-grown diamonds are real and are not fake diamonds. Man-made diamonds are 100% carbon and have the exact same chemical properties as mined diamonds. Lab created diamonds are grown by recreating the conditions underneath the Earth that result in diamond growth: pressure, heat, & carbon. Learn more about why lab diamonds are not fake.
Lab grown diamonds are not the same thing as diamond simulants such as cubic zirconia, moissanite, or a CZ with a diamond like carbon (DLC) coating. Learn more about lab diamonds vs diamond simulants.
Is a Cubic Zirconia (CZ) the Same Thing as a Lab Grown Diamond?
No. Diamonds are made entirely from carbon, whereas cubic zirconia contains zero carbon! CZs are much weaker than diamonds and have different light performance and patterning. Any jeweler can easily tell the difference between a diamond and an inferior diamond simulant such as CZ or moissanite.
Is a Synthetic Diamond the Same Thing as a Lab Grown Diamond?
Yes. Laboratory grown diamonds can be referred to as lab created diamonds, grown diamonds, synthetic diamonds, man-made diamonds, cultivated diamonds, or cultured diamonds. That being said, we believes that synthetic is a scientifically inaccurate term for laboratory grown diamonds.
Can a Jeweler Tell That a Diamond is Lab Grown?
No. Our lab diamonds and natural diamonds of the same quality look the same, even to a trained eye. Traditional jewelers' tools such as microscopes or loupes cannot detect the difference between a laboratory-grown diamond and a natural, mined diamond.
The low-cost diamond testing tools used by many jewelers are designed to test between fake diamonds (CZ, moissanite) and diamonds. These cheap tools are rudimentary and are not able to accurately differentiate between mined and grown diamonds.
The gemological equipment needed to reliably determine if a diamond is mined or grown is quite complicated and costs over $10,000. The most accurate detection method, Photoluminescence Spectroscopy, requires deep freezing the diamonds to −320°F (−196°C)! Most jewelers do not own such equipment due to the high cost and complexity.
That being said, all of Ada's lab diamonds above 0.50ct are graded by third party, non-profit gemological organizations and certified as lab grown with a microscopic laser inscription. A jeweler can utilize a microscope and look up the unique ID of the diamond in a public database. We are proud of the origin of our diamonds and do not try to hide the fact that they are lab grown.
