A fine set of four oval cabochons showing the remarkable play of color that makes Ethiopian Welo opal so highly prized. Each stone displays shifting flashes of red, orange, green, and blue across a translucent to semi-translucent body, creating a lively display under light. Welo opals are formed in volcanic deposits and are known for their ability to show multiple colors from different angles, an effect called opalescence. These gems are excellent for jewelry or for collectors who appreciate the dynamic beauty of natural opal.
