21.25CT High Quality Lab Grown Emerald Necklace 925 Sterling Silver

Weight:(21.25)CT

Stone:(Lab-grown emeralds)

Lab-grown emeralds are emerald gemstones created in controlled laboratory environments using processes that mimic the natural formation of emeralds. They have the same chemical composition, crystal structure, and optical properties as natural emeralds, but they are usually more affordable, clearer, and ethically sourced.

### Key Details about Lab-Grown Emeralds:

* Composition: Made of beryl (Be3Al2(SiO3)6), like natural emeralds.

* Appearance: Often more transparent and have fewer inclusions than natural emeralds, though some are intentionally grown with "jardin" (natural-looking inclusions) for authenticity.

* Growth Methods:

* Hydrothermal: Simulates conditions in the Earth's crust; results in high-quality, natural-looking stones.

* Flux-growth: Uses a molten flux to dissolve nutrients; slower but can produce cleaner crystals.

* Price: Typically 30–70% less than natural emeralds of comparable size and quality.

* Durability: Same as natural emeralds, with a hardness of 7.5 to 8 on the Mohs scale, but still somewhat brittle due to internal inclusions.

* Ethical & Eco-Friendly: No mining is involved, which appeals to eco-conscious buyers.
