FAQ
Are lab-grown diamonds fake?
No — they are 100% real diamonds grown via CVD/HPHT, chemically identical to mined stones. Only the origin differs.
How much cheaper than natural?
Roughly 60-80% on the same design. A 0.30ct ring (Silver 925) starts at 21,000 THB with a natural stone vs just 8,000 THB lab-grown — and a full 1.00ct lab-grown ring starts around 18,000 THB.
Will it cloud or fade over time?
No. At 10 Mohs hardness — the same as natural diamond — it never clouds or changes color, and ZILVY lifetime care is included.
