Welo Opal – The Precious Stone of Ethiopia

Welo opal, also known as Ethiopian or hydrophane opal, is one of the newest and most exciting opal discoveries in recent years. Found in Ethiopia, Welo opal is prized for its unique characteristics that make it a true gem among the precious stones of the world.

What is Welo Opal? Welo opal is a variety of hydrophane opal found primarily in Ethiopia.

It is a type of precious opal that exhibits a unique play of color, or fire, when viewed from different angles. Welo opal is known for its translucence, which allows light to pass through it and create stunning optical effects.

Unlike other types of opal, Welo opal is considered a hydrophane opal. This means that it has the ability to absorb water and change its appearance when wet.

When dry, Welo opal is known for its bright, vivid colors and translucence. When wet, the colors can become muted and the stone may appear more opaque.

History of Welo Opal

Welo opal was first discovered in Ethiopia in 2008 in the Wollo region. The discovery of Welo opal caused a stir in the gemstone industry, as it was one of the first major opal discoveries in over a century.

Since its discovery, Welo opal has quickly gained popularity among collectors and jewelry designers alike. The gemstone has been used to create stunning pieces of jewelry, and its unique properties have made it a favorite among gemstone enthusiasts.

Characteristics of Welo Opal

Welo opal is known for its unique characteristics that set it apart from other types of opal. The gemstone exhibits a stunning play of color, or fire, that is caused by the diffraction of light as it passes through the stone.

This creates a mesmerizing effect that is often compared to the Northern Lights. Welo opal is also known for its translucence, which allows light to pass through it and create stunning optical effects.

When viewed from different angles, the gemstone can appear to have different colors and patterns, making it a true gem among precious stones. One of the most unique characteristics of Welo opal is its ability to absorb and release water.

When dry, the gemstone is known for its bright colors and translucence. When wet, the colors can become muted and the stone may appear more opaque.

This makes Welo opal a truly unique gemstone that is prized for its distinctive appearance.

Crazing in Welo Opal

One potential issue with Welo opal is crazing. Crazing refers to the small cracks that can appear on the surface of the gemstone over time.

While crazing can impact the appearance of the gemstone, it is not uncommon in opals and does not necessarily indicate a lack of quality. To prevent crazing, it is important to take good care of Welo opal jewelry.

This can include avoiding exposure to harsh chemicals or extreme temperatures, and storing the jewelry in a way that minimizes the risk of damage.

Gem-Quality Welo Opal

Gem-quality Welo opal can be quite valuable and is often used in high-end jewelry designs. To be considered a true gem, Welo opal must meet certain quality standards, including color, clarity, and cut.

Color is one of the most important factors in determining the value of Welo opal. The gemstone should exhibit a vibrant, consistent play of color that is not too dark or too light.

Clarity is also important, with gem-quality Welo opal exhibiting minimal internal flaws or inclusions. Finally, the cut of the gemstone can also impact its value.

Gem-quality Welo opal is often cut to highlight its unique play of color and translucence, while also maximizing its size and overall appearance.

Conclusion

Welo opal is a unique and fascinating gemstone that is prized for its stunning play of color and translucence. While it can be subject to crazing, with the proper care and maintenance, Welo opal jewelry can be a valuable and beautiful addition to any collection.
