Lab-Grown Diamonds vs. Natural Diamonds
Both are real diamonds. The difference is origin: natural diamonds form underground, while lab-grown diamonds are created in a controlled environment.

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.
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.
Are lab-grown diamonds ethical?
Lab-grown diamonds are considered a more sustainable and responsible alternative to mined diamonds. They are created using advanced technology with a lower environmental impact and without traditional mining practices.
Do you offer free shipping?
Yes. We offer free insured FedEx shipping across Canada and the USA for all orders over $400. For orders under $400, a flat shipping fee is applied at checkout, which still includes full insurance and tracking to ensure your jewellery arrives safely.
