Lab Grown Emerald
A lab-grown emerald is a gemstone that is created in a laboratory using processes that simulate the natural conditions under which emeralds form in the Earth's crust. These lab-created emeralds have the same chemical composition and crystal structure as natural emeralds but are produced in a controlled environment. They are typically grown using the hydrothermal or flux methods, which involve the use of mineral precursor materials, high pressure and temperature conditions to encourage emerald crystal growth. Lab-grown emeralds can closely mimic the appearance and properties of natural emeralds, including their vivid green color and lustrous transparency, making them a more affordable and sustainable alternative to mined emeralds.
Here are few key points about Lab Grown Emerald
Lab-grown emeralds have the same chemical composition as natural emeralds, primarily consisting of beryllium aluminum silicate with trace amounts of chromium and/or vanadium that give them their green color.
Both lab-grown and natural emeralds have a Mohs hardness of 7.5 to 8, making them moderately hard gemstones. This means they are more susceptible to scratching than rubies or sapphires.
Lab-grown emeralds can be produced in various shades of green, ranging from light to deep green. The presence of trace elements like chromium and vanadium influences the precise shade of green.
The specific gravity of lab-grown emeralds is also similar to that of natural emeralds, around 2.67 to 2.78.
Lab-grown emeralds are often cut and faceted to enhance their appearance and sparkle.
Lab-grown emeralds offer an ethical and sustainable alternative to mined emeralds, as they do not contribute to the environmental and ethical concerns associated with emerald mining.
