FAQ
Are lab‑grown diamonds real diamonds? Yes. They share the same chemical composition and optical properties as mined diamonds; the only difference is their origin.
Do lab‑grown diamonds have resale value? The resale market is still developing; values can be lower than those for natural diamonds. However, their lower purchase price offsets depreciation, making them a smart choice for many buyers.
Will lab‑grown diamonds lose their sparkle over time? No. Like natural diamonds, lab‑grown diamonds maintain their brilliance indefinitely if properly cared for.
