Lab-Grown Sapphire generation techniques

- **Verneuil Process**: low cost, high yield, but bubbles and color bands may be present.

- **Hydrothermal**: closer to the natural formation environment, high clarity, uniform color, higher price.

- **Flux-Grown**: produces large gemstones, but has a long growth cycle (several months).

Lab-Grown Sapphire

- **Composition**: Same as natural sapphire (Al₂O₃ with iron/titanium coloration).

- **Hardness**: 9 Mohs (second only to diamonds), suitable for everyday wear.

- **Color range**: from light blue (Sky Blue) to deep royal blue, and can also be cultivated in pink, yellow, etc. (non-blue is called “colored sapphire”).
