Emerald – $500,000/Kg

This lovely variation of the Beryl gem has high financial value as well as aesthetic appreciation. Emeralds are usually mined from Egypt, Austria, Pakistan, and a rare type can also be found in Columbia.

The green stones can go as high as $500,000 per kilogram, their value decided by a number of factors like clarity, color, rarity, and structural integrity. They come in many hues ranging from blue-green to yellow-green, with the core hue being green. Emeralds make for exquisite engagement rings despite their high pricing. What we wouldn’t give to own one!
