In the realm of opal, recognition is paramount; it helps identify the stone’s origins and value, ensuring that collectors make informed decisions. Here’s a closer look at the primary varieties of Ethiopian opal:

Welo Opal

Welo opal stands out as one of the most sought-after varieties. Hailing from the Welo region, this opal showcases a remarkable interplay of colors, often exhibiting vibrant reds, blues, and greens that can leave onlookers spellbound.
