Arkansas Adularia Quartz Crystal Point

$28.00

So here is something special! Arkansas quartz is always lovely, but these adularia included points are rare and interesting, too. "Adularia" is a varietal name for a potassium feldspar of simple, prismatic habit. It is the name for the wedge-shaped, pseudo-orthorombic form of orthoclase found most commonly with Swiss Alpine quartz, and it's quite unusual for it to show up in American quartz, and this is found in the Hamilton Hill Mine in Arkansas. The adularia is the white specks inside these crystals. It looks like kosher salt, and is present in all three crystals. I suspect, but have yet to confirm that the golden specks are golden adularia, as they all have the same crystal structure.

Quartz crystal mining was begun at Hamilton Hill shortly after the Civil War by William Hamilton and John Neal. Hamilton worked the deposit for about 25 years. Work at the mine had been restarted a few times since and has produced some outstanding large specimens. Then in 2013 the mine was reopened by it's current owners and has been producing some great stuff again. So far they have hit a major pocket of adularia and quartz combination specimens which are unique in quality and size for North America.

That's a lot of info, I know, but I wanted to share some info about what makes them so special. These are great for American mineral collectors, quartz collectors, included quartz collectors, and odd quartz lovers.
