Opal is a vitreous or dull mineraloid of white, yellow, red, orange, green, brown, black to blue. Although it is still regarded as a mineral species for historical reasons, opal is not a true mineral in the accepted sense of the word as it is variably composed of poorly crystalline material (mindat.org) Johannes Schmidt (talk) 14:04, 29 February 2024 (EST)
