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.
