An absolutely astonishing, Pakistan-quality aquamarine from the famous but small Fano Mine just over the border from San Diego County proper and so close enough for this collection...it is extremely significant as a California beryl crystal but beyond that it is a superb display-quality aqua by any standard. This is a well-known specimen in San Diego circles and is regarded as the finest aqua from this small mine that has produced the finest gem aqua crystals in San Diego, though only a few of them and only many years ago!
