Item #27692 Pyrite 16.0x1.0x8.5 cm Largest Crystal Size: 32mm $140.00 Tea Cove Port au Port Peninsula Newfoundland, Canada A huge cannon ball of a concretion from the amazing locality at Tea Cove. At this locality, pyrit concretions weather out of the shale underwater on the ocean floor and that is where you collect them! At low tide, you walk around in the water, reaching down and picking up the concretions. They, generally, have this nice brownish patina and often have barnacles attached to them, as though to attest that they were, in fact, in the ocean. You can see a couple of white barnacles on this one at the lower right. The crystals range in size and are curved, rounded cubes with minor modifications. Extra postage, please! :) Impressive large cabinet specimen!

There is a sharp 5mm weloganite crystal on one side of the vug that has some very good clusters of dresserite on it. There are numerous sharp, very transparent, colourless dawsonite crystals throughout the vug. Very difficult for me to photograph them with my set-up due to their clarity. At one end of the vug is a sharp, highly lustrous, half-galena crystal. Interesting one!!	Item #27676 Willemite, Hematite 4.0x3.8x2.2 cm Largest Crystal Size: 4mm $45.00 Tsumeb Mine Otjikoto Namibia This specimen is largely composed of interlocking, hexagonal crystals of willemite that have partially intergrown with earthy hematite.

Item #27652 Celestine 8.4x5.5x2.8 cm Largest Crystal Size: 20mm $110.00 Lime City Wood County Ohio, USA This is a handsome and interesting piece! It is a plate of white celestine crystals with a darker core that shows through in center of the terminations. Some people say that these types of celestine crystals from this locality are partially altered to strontianite. I'm not sure. Interestingly, each celestine crystal has a couple of few small calcite crystals in the center of the termination. As well the celestine is fluorescent, although not like in the photo. The crystals show as cramy white on the prisms while the terminations are a yellow colour. I could not seem to get hew fluorescent colours correct in the photo here. Excellent specimen from a classic mid-west locality.

The crystal is also very fluorescent yellow! A few other smaller crystals are also present as you can see from the poor fluorescent picture. You can do better! This location is where the standard zircons for geochronological dating come from! Nice one!	Item #27632 Scorodite, Alunite 10.0x6.5x7.0 cm Largest Crystal Size: al-5mm, sc-1mm $140.00 El Indio Mine Elqui, Coquimbo Chile The front of this specimen is covered with beige crystals of alunite which, in turn are generously sprinkled with balls and crystals of very light blue scorodite crystals.

The catapleiite crystals are colourless, gemmy and very well formed pseudo-hexagonal crystals. Most of the crystals are in the recess between natrolite crystals and difficult to get at with the lens but I've tried to show a couple of the exposed ones. What a great mineral!

Nice one!
Item #27567 Hochelagaite, Analcime, Synchysite, ps. Petersenite 4.3x4.3x3.4 cm Largest Crystal Size: hoch-micro $65.00 Mont Saint-Hilaire Quebec, Canada As an analcime specimen, it doesn't quite make it because of a large contact on the largest analcime crystal. Still looks great though and there are several clusters of tiny balls of the rare niobium mineral hochelagaite here and there on the piece. As well, there are loads of hollow pseudos of synchysite after sharp, hexagonal petersenite crystals. Very interesting piece!
