3.5 x 2.6 x 2.4 cm. An aesthetic and classic cluster of splendent, twinned, wine-red rutile crystals perched on matrix from Graves Mountain, Georgia. The rutile crystals exhibit textbook crystal structure and they are pristine. An excellent rutile piece from the Ryan Bowling Collection and collected by Terry Ledford, a well-known Georgia locality field collector.
10.1 x 8.0 x 4.9 cm. A fine cabinet combination piece from the Morchnerkar area of Austria. Lustrous anatase crystals to 3 mm are scattered on a jackstraw matrix of very glassy, transparent quartz crystals. Sagenite or mesh-like, herringbone-patterned, wine-red rutile needles are located near the anatase crystals. Ex. Rolf Wein and Josef Stuckl Collections.
Sharply twinned rutile from a very unusual pegmatitic locality. This is rare material, that apparently was mined last year and appeared on the market at an Italian show early this spring. 2.7 x 2.5 x 1.5 cm
2.4 x 1.0 x 0.1 cm. A razor-sharp thumbnail of North Carolina rutile, an elongated crystal that is lustrous as glass and terminated on top. Ex. Carlton Davis Collection.
3.5 x 3.2 x 2.6 cm. Cavradi hematites are a classic, treasured by the strahlers who find them in alpine mountain clefts. This is a superb miniature of excellent quality. It features a 3-dimensional 2.7-cm crystal , freestanding and fully exposed, on contrasting white matrix of feldspar. The crystal has fat beveled terminations, not the thin blades you often see. It is accented by small, bright red rutile crystals which grow on the surface and serve to highlight the incredible metallic lustre around them. And, lastly, the back of the crystal is freestanding above the matrix and is half-exposed above the matrix. From a private European collector specializing in Swiss classics.
A single quartz point so richly included that I am not sure there is as much quartz as rutile in the upper half! A really unusual piece not for the association per se, but for the sheer extravagance of the inclusions. 3.2 x 3 x 3 cm
4.4 x 3.6 x 3.5 cm. A superb miniature Georgia rutile by any standard, historic or not, that happens to have ended up already in Europe by the 1890s. The accompanying label from the collection of Dr. Carl Riemann dates the piece to the 1880s-1890s. The crystal is intensely lustrous, has the rare and desirable red flash when lit strongly, and is complete all around. Also, note the sharply visible twinning atop the termination. Ex. Helmut Bruckner and Dr. Carl Riemann Collections.
A superb rutile specimen, showing the classic elbow twinning and the highly desirable deep red color and striated lustrous sides. The longer twin even has a perfect termination! You would be hard-pressed to find a better rutile at a reasonable price 5.1 x 2.5 x .5 cm
A very large (up to 1 cm thick!) crystal with rutile's classic high luster, deep red color, and striated sides. The major termination is good, but not perfect. Brazilian rutiles of this size and quality are simply not that common, even though lesser pieces are very common. 4.2 x 1.1 x .8 cm
3.3 x 2.5 x 0.6 cm. Glittering golden crystals of rutile shooting off a shiny-metallic platy crystal of hematite, from Brazil.
An aesthetic and sharp cluster of three lustrous, dark-red rutile crystals nicely mounted on matrix. They meet at the apex of each and perhaps this is some weird twinning?? 3.6 x 3.3 x 3.0 cm
9.8 x 8.7 x 3.1 cm. This is a bizarre Pakistani specimen, quite different from any rutile I have seen before from this region. It is a very aesthetic piece with a crosshatched cluster of pipe-like (for lack of a better word) rutile crystals that runs along the plate of albite and green titanites, like irrigation pipes with a few outlets sticking up here and there. Ex. Richard Kosnar Collection (he specialized in minerals of the world's alpine type deposits).
2.4 x 0.6 x 0.4 cm. A classic geniculate or knee-bend twinned thumbnail rutile crystal from a historic locality - Stony Point, North Carolina. This is a beautifully gemmy, parallel-growth, reddish-brown crystal. Ex. Carl Davis Collection.
8.7 x 5.2 x 3.9 cm. This is a huge, 340-gram specimen from this very famous old locality. It is a little bit worn, has some very minor damage on the sub-terminations, but overall is in surprisingly good shape for such a large, old, and soft crystal. Note the term "rutile money" on the label, perhaps indicating how these were traded around like money at the time? According to MINDAT: Of Genth; "Finest locality in Sadsbury township, for the principle locality for Rutile in Chester County PA. Considerable quantity of Rutile had been collected in the early to mid 19th century, Doubly geniculated crystals up to a pound in weight had been found loose in surrounding soils and worked up by manufacturers of dental supplies, for coloring artificial teeth. Also found embedded in Quartz and soils throughout the 7 mile long valley. Note that the mass of this crystal is then pretty close to the largest size reported in the above notation.
