# SMQ-63, $30.00 50% Discount - Sale Price $15.00
Dims: 1.90x0.60x0.53in (4.82x1.52x1.36cm) .... Wt: 0.320oz (9.00g) .... Loc: Devels Head, Douglas County, Colorado, USA
Another Devil's Head smoky specimen, this one consists of 3 crystals (two intergrown), the largest of which is tapered and all of which are quite transparent, although black. But with the aid of a bright light and a loupe, it appears that the black is caused by minute black inclusions instead of radiation damage as with many smoky quartz crystals.
# SMQ-62, $30.00 Sold!
Dims: 1.66x1.01x0.59in (4.21x2.57x1.49cm) .... Wt: 0.64oz (18.0g) .... Loc: Devils Head, Douglas County, Colorado, USA
This does not appear to be the typical radiation-darkened smoky quartz that is so common. Rather, this crystal is quite transparent, yet superficially appears nearly black. But a bright light shows that it is quite transparent, and I suspect (but could not find any sign of proof) that the black is largely a surface effect.
# SMQ-60, $75.00 Sold!
Dims: 3.71x2.52x1.24in (9.42x6.40x3.14cm) .... Wt: 7.4oz (209g) .... Loc: Mexico
This is a "Fenster Quartz" specimen, showing stubby, generally doubly-terminated crystals, largely transparent, partly colorless and partly gray (smoky), and some of the crystals show the stepped faces and partly hollow interiors of Fenster specimens.
# SMQ-61, $98.00 50% Discount - Sale Price $49.00
Dims: 4.01x2.48x2.00in (10.18x6.31x5.09cm) .... Wt: 10.3oz (292g) .... Loc: Ladakh Valley, Lahul Spiti, Himachal, Pradesh, India
I wasn't certain how to characterize this specimen. It's clearly quartz, and my first impression was smoky quartz. Close examination reveals that most of the gray-to-black coloration is due to thousands of tourmaline crystals, not radiation-induced damage (the source of blackness in most smoky quartz crystals). Peering through one of the clear faces and down the long axis of a few of the crystals convinced me that there was sufficient (although pale) grayness to qualify as smoky quartz. In any case, the individual crystals are slighly flattened, doubly terminated, tapered, and generally have a dull luster, although some facets are exceptionally clear. Also, some of the tourmaline crystals can be seen to protrude from one quartz crystal, through the air, and back into another one - a very unusual feature.
