LAB GROWN OR NATURAL?
Which one is right for you?
Both are real diamonds — same crystal structure, same independent certification. The difference is how they were formed and what you pay for them.

Diamonds FAQ
Questions, Answered Simply.
What most people want to know before choosing a diamond.
Yes. Lab grown diamonds have the same chemical composition, crystal structure, and optical properties as natural diamonds. They are graded by GIA and IGI using identical standards.
Origin and price. A natural diamond formed in the earth over billions of years. A lab diamond is grown in weeks under controlled conditions. The physical result is identical — the cost is not.
Not with the naked eye. Even trained gemologists need specialized equipment. The sparkle, hardness, and appearance are identical in both.
It means an independent laboratory — not the seller — has graded the diamond on cut, color, clarity, and carat. Every diamond on Brilliance comes with a grading report from GIA or IGI.
Lab diamonds have lower resale value than natural diamonds. If long-term value retention matters, natural is the better choice. If maximum size and quality for your budget is the priority, lab grown wins.
