Any Effenbergerite is a good Effenbergerite, considering how rare this species is, and how few specimens ever come to market. This is small, but it hasseveral spots of eye-visible Effenbergerite crystallization upon it and should be considered significant enough to add to any rarities suite. TYPE LOCALITY and as far as I can see on MINDAT, the ONLY locality for this species.
