A large fine Rainbow Opal weighing a total of 3.07 carats (treatment: smoked) from the famous Welo region in Ethiopia.
Directly from the famous Wollo Province, the epicenter of East African opal deposits, this exceptional gemstone combines natural purity with artful smoking (light opals are exposed to the smoke of a fire to achieve this hue) – for a deep black base tone and maximum color play. Color play varies depending on the lighting!
The hydrophane, water-containing opal shows an intense, three-dimensional spectrum of red, green, blue and gold — rarely seen in this saturation and size.
Natural silica gel structures in the stone bend the light into the finest microarchitecture — a mineralogical wonder.
With 3.07 ct, this is an impressive investment and collector's stone.
Raw or platinum-set: a symbol of style, rarity, and substance.
Invest in geological excellence with lasting value.
The stone comes from the Semien Wollo Highlands region, and is therefore referred to as Welo opal.
