Description from the seller

2 emerald stud earrings / new

Set in 925 sterling silver

Total weight: 8.6 ct / 1.72 g

8.5 mm x 6.3 mm x 16.4 mm

New and unworn


Emerald is a dark- to light-green variety of the silicate mineral beryl with the chemical composition Al2Be3[Si6O18]. The color of emerald, whose range of variation extends from a dark blue-green to a light yellow-green, is caused by small impurities of chromium (Cr3+) and vanadium ions (V3+).

Just as the pure mineral beryl crystallizes, emerald crystallizes in the hexagonal crystal system and typically forms hexagonal, prismatic to columnar crystals with a glassy luster on the surfaces. Its Mohs hardness of 7.5 to 8 is comparable to that of beryl.
