Dark Base Ethiopian Opal from Welo – 4.72 grams

A striking Ethiopian opal featuring a darker body tone that enhances its vivid play-of-color. Bright flashes of red, orange, green, and subtle violet ripple across the surface in bold, flowing patterns, giving the stone strong visual depth and contrast.

This piece is partially backed by natural host rock, framing the opal and adding specimen character. All of the exposed opal material shows gem-quality color and brightness, with no additional cutting material extending behind the rock. What you see is the full extent of the opal, making it ideal as a collector specimen or for careful cutting depending on the desired result.

The darker base combined with intense color makes this a particularly eye-catching piece from Welo.

Please Note: Ethiopian opals are hydrophane and can absorb moisture. Water exposure (including during cutting) may temporarily affect their appearance, but as the stone dries, its color will naturally return over time. These opals should be stored in a dry environment. Avoid prolonged exposure to oils or chemicals, as oils can be absorbed and may permanently affect the appearance.
