Comment: **NOT A NATURALLY FORMED CRYSTAL** This is a specimen of quartz shot through with glittering acicular crystals of lepidocrosite - a lot rarer, of course, than the rutile-in-quartz specimens you see from Brazil. It has been cut from rough crystal (these are not the natural faces), then brought to a very high polish. Though the high reflectivity of the lepidocrosites makes them appear silvery, you can see flashes of red, as this is their real color - a gemmy red - you sometimes see lepidocrosite included in quartz specimens from Brandberg, though not in the acicular form - and in those, you can clearly see the red color. incredible for what it is, though a lapidary (polished) object of art
