4.3 x 2.5 x 2.1 cm. I received just before the show a parcel from Brazil with about 50 crystals from one single pocket, showing some of the best equant form I have ever seen in the species. These crystals are uniformly fat and deep, not skinny, as from past finds in Brazil. Many, such as this one, were included with golden rutile which adds welcome color flashes on the surface. Also, they have wonderful brown color and lustre, like a fine wood-grained table of high polish. Most xenotime is dull and earthy. Out of the whole lot, this was the finest and most robust crystal, and it is in good condition as well (complete all around). This is MAJOR, of an incredible quality for the species where crystals of this size are normally earthy and dull.
3.9 x 3.7 x 2.7 cm. This sharp, transparent quartz crystal is shot through with golden needles of rutile that sparkly and shimmer in the interior.
10.4 x 8.3 x 5.4 cm. A BIG and RICH specimen of transparent, euhedral quartz penetrated by glittering golden needles of rutile, extending from a platy base of hematite (this association is well-known from this locality).
2.0 x 1.6 x 1.1 cm. A classic, rare, complete rutile crystals form this famous 1800s-era US locality.
2.4 x 2.0 x 1.8 cm. An excellent sixling of rutile. Ex Lawrence Conklin.
5.5 x 3.9 x 3.7 cm. A water-clear quartz crystal all shot through with glimmering, golden needles of rutile.The metallic mineral is hematite, frequently associated with these. The faces of this crystal are so lustrous and clear, it is just a great example of one of these, really striking!
2.8 x 2.6 x 2.0 cm. One titanium mineral pseudomorphing another titanium mineral, it could only happen at Magnet Cove. High luster and a dark gray metallic color highlight this crystal. Ex. Carnegie Museum Collection.
Crystals to 5 mm. Literally hundreds of dark gray brookite/rutile crystals, to .5 cm across, fill up this vial. Ex. Carnegie Museum Collection.
Crystals up to approximately 2 cm. This is a collection of 110 rutile crystals from the emerald and hiddenite deposits of North Carolina. The largest crystals are approx. 2 cm in length and show their internal red highlights. Ex. Carnegie Museum Collection.
5.0 x 4.5 x 4.2 cm. Mono rutiles are known for their flashy luster and sharpness, as seen in this isolated 1.3-cm crystal which has a sheen that is almost metallic in appearance. The faces flash like crazy! From the well-known California collection of Charles Hansen.
9.2 x 4.2 x 2.3 cm. This is a sharp, transparent quartz crystal in great condition (a couple of minor contacts) that is shot through with hair-like crystals of rutile - which you can clearly see due to the extreme clarity of the quartz. Under good light, these rutile crystals gleam like steel needles!
6.2 x 5.6 x 4.6 cm. A brilliantly shimmering and rich rutilated quartz from a most unusual locality! Such pieces, so rich and colorful, are VERY rare for the Swiss alps. This crystal is complete and presents nicely from the display face, though rough on the back faces and broken on the bottom. Ex. Richard Hauck Collection.
6 x 4.6 x 2.2 cm. This crystal has incredible lustre and transparency, showing off the internal rutile crystals which are also so bright they look metallic, and shine out starkly from within! A competition level quartz piece for the Alps, very rare in such quality! Ex. Richard Hauck Collection.
5.8 x 5.2 x 2.7 cm. A polished section of a rutilated quartz crystal showing unusually individual and robust rutile crystals within. From the Cliff Awald Collection(he wrote a pamphlet about inclusions in quartz in the mid-1950s for the Buffalo Museum of Science). Ex. Richard Hauck Collection.
5.3 x 4.6 x 2.7 cm. You are now probably familiar with this combination from Brazil of golden, acicular crystals of rutile with platy-metallic hematite. This specimen looks great from both sides. On one side you have this pretty 30-degree burst on two different levels, and on the other, a large, gleaming plate of hematite with rutile between its spokes. A really rich and pretty one!
