Once used by early man as tools, Ethiopian opals have only begun to be mined in the 1990s. Usually found in a round nodular form within a 3 meter thick layer of welded volcanic ash, these opals are plentiful, yet only about 1% of these nodules contain any color at all, let along the striking diversity of color that this piece exhibits. These amazing gems are so new to the market, yet they are gaining in popularity at an exponential rate. To find one of such large size and exquisite beauty is a rare treasure.
