Aquamarine is the bright blue variety of beryl species. Its colour can be pale to dark blue or greenish blue which is caused by iron trace elements. Aquamarine derives from the Latin words “aqua marina” which mean water of the sea. Depending on the transparency of the stone which can be anything between transparent to almost opaque, aquamarines are cut into faceted gems, cabochons, beads or carvings and occasionally rough crystals are left intact in their hosting rocks and sold as gorgeous rough specimens. Usually, aquamarines look clean when seen with the naked eye. A typical inclusion of the stone is what is known as “rainfall” consisting of parallel growth tubes. Aquamarine’s lustre is vitreous, it rates 7.5-8 on the Mohs scale which makes it suitable for jewellery that has secure settings to protect the stone from wear.;Stone Size: 22.4x9.2;Carat Weight (ct): 7.46
