Hyalite opal mineral / gem specimen Spruce Pine NC fluorescent unique locale
Back around 1970 or so, a buddy and I stumbled across a pocket of hyalite opal in a very small prospect just off the road, not far from the McKinney Mine in Spruce Pine, North Carolina. To the best of my knowledge the prospect had no name. I’ve been unable to find it since—it may have been destroyed years ago during road improvements—so, as far as I know what I have here is all there is, forever, from that locale.
The pocket itself was about as big as an end table, horizontal, with hyalite on both the top and bottom surfaces. The pegmatite on the top was already starting to fracture and some of the pieces had fallen; others were loose enough that you could pull them out by hand. The hyalite on those specimens was attached to the matrix.
Curiously, the hyalite on the bottom had detached from the pegmatite and was just lying there, loose. It was also a slightly different color from the hyalite above—a little more of a tan-golden color, whereas the hyalite from up top was very pale, close to colorless.
It’s fluorescent, in the green color typical of hyalite from other Spruce Pine locales such as the Chalk Mountain Mine or McKinney Mine.
I’ve got a couple of specimens in my cabinet but the rest of this is just sitting and that’s no way to treat perfectly good specimens. With that in mind, I’m going to put up a series of auctions on eBay to release these to people who will love and admire them properly.
ABOUT THIS BATCH:
Batch #4
These fragments are different from the previous auctions for small pieces in that they are on pegmatite matrix. For scale, the black foam tray is 7-1/8” x 9-1/4”. Some of the hyalite is nearly clear, some is tannish to cream colored. As you can see from the photos, they vary in how strongly they fluoresce. Some of it is that no matter how I tried, I was having trouble juggling both my phone and the UV light—some of the lower, center specimens are actually better than they look in the photo. Note that the two largest pieces just don’t have that much hyalite on them. Some of the smaller pieces are fairly thickly crusted.
In total, the hyalite weighs 206 grams. Just to be conservative, I’m going to call it 200 grams.
The matrix is pegmatite, meaning quartz, feldspar, and mica, with a few garnets or, more precisely:
Albite, var: Oligoclase
Mica, var: Muscovite
Mica, var: Biotite
Garnet, var: Almandine
Quartz
