Description

A rare 2.50ct Black Opal mined in the Welo Region of Ethiopia in 2015.

Certified by HKD Gemmological Laboratories Canada in May 2015.
Outstanding play of colour with dominant red and green flashes

Opals are formed from centuries upon centuries of seasonal rains that leach microscopic silica particles from sandstone, carrying them deep into underground fissures and cavities. As the deposited materials dry, the microscopic silica spheres become compressed into a closely-packed lattice. As light travels through this microstructure, it creates a dazzling kaleidoscope of flashing rainbow colors, called play-of-color.
“They say you can see the whole universe in opal, that’s how old they are. ”
