Klein Spitzkopje is famous for topaz, not for beryl. It is the location from which Charlie Key sourced much of the first colorless topaz for treatment to London Blue in the 1980s, and has been very productive. However, aquamarine from here is rare, and intact crystals all the more so. They have a shocking, intense blue color saturation that is hard to describe (we hope the video will convey it), subtly different than what you see from Brazil or Pakistan. I would say the color is "robust" in a way hard to quantify, but the human eye can see it anyways. Few large gemmy crystals of this size survived the cutting industry which is much easier for miners to access there. This is complete all around, undamaged, and has never been to a lab for professional cleaning (we can see pocket iron staining), so it should brighten and improve with lab work if desired. However, Bill was a purist and preferred his crystals as natural as possible, if they were naturally good - as this is. It survived the last 40 years or so in the beryl collection of Bill Larson/Pala Intl, on display in their company gallery in San Diego (it comes with the old laminate label from the 1980s).
