Common Questions
Are lab-grown diamonds real?
Yes. Lab-grown diamonds are real diamonds with the same chemical, physical, and optical properties as mined diamonds. They offer the same brilliance, durability, and beauty as natural diamonds.
Do lab-grown diamonds sparkle the same as natural diamonds?
Absolutely. Lab-grown diamonds have the same fire, scintillation, and sparkle as mined diamonds because they are made of the same material — pure crystallized carbon.
How does the environmental impact of lab-grown diamonds compare?
Lab-grown diamonds are created in controlled environments without traditional diamond mining. Their overall environmental impact can vary depending on the energy sources and production methods used. If this is important to you, ask what production or sourcing information is available for the specific diamond.
Are lab-grown diamonds certified?
Yes. Our lab-grown diamonds are independently graded and certified by respected laboratories such as IGI and GIA, using the same standards applied to mined diamonds.
Do lab-grown diamonds last forever?
Yes. Lab-grown diamonds are just as durable as natural diamonds and are suitable for everyday wear. They rank 10 on the Mohs hardness scale, making them one of the hardest materials on earth.
