Amazon Quiz: Which color is an emerald?
Pink
Purple
Green
Yellow
Answer: Green
The gemstone Emerald is a form of the mineral beryl that is tinted green by minute quantities of chromium or at times vanadium.
On the Mohs scale, beryl has a hardness range of 7.5-8. The majority of emeralds are heavily incorporated, making them generally weak in terms of toughness (resistance to breakage). Cyclosilicate is what makes emeralds.

Emeralds are rated using the four fundamental criteria—the four Cs of connoisseurship—as are other coloured gemstones: colour, clarity, cut, and carat weight. In grading coloured gemstones, colour is typically by far the most significant factor.
However, clarity is ranked as a close second in the grading of emeralds. For an emerald to be regarded as a top gemstone, it must have a high degree of transparency in addition to the pure, verdant green hue specified below.
The green vanadium-bearing beryl was included to the definition of emerald by the American jewellery industry in the 1960s. Vanadium emeralds bought in the United States as emeralds are therefore not regarded as such in the United Kingdom and Europe. In America, phrases like “Colombian emerald” are frequently used to distinguish between traditional emeralds and the new vanadium kind.
