This mine produced the world's finest liroconite specimens more than 150 years ago in the early to mid 1800s. Perched nicely here on quartz crystals are several, intensely blue, very lustrous, liroconite crystals, to 5 mm across. This is a pretty very old, specimen almost never found in dealers stocks. The color intensity and saturation here are top quality, and it is a rich specimen for the price compared to what I have seen over in Munich, in Euro pricing, especially. I buy Every GOOD ONE of these I see, that I can get ahold of - and i've had a whopping dozen or so in 20 years!? That tells you something of the rarity.Joe Budd Photos
