Item #15103 Celestine 10.5x8.8x6.7 cm Largest Crystal Size: n/a $40.00 Georgetown Ontario, Canada Bright orange crystals of celestine are compacted into a cavity in dolostone. Unusual form of celestine!	Item #17610 Gypsum, var Selenite 15.0x9.0x5.6 cm Largest Crystal Size: 115mm $65.00 Lafarge Quarry Wentworth County Ontario, Canada One big, incomplete but very cool crystal of gypsum sits on top of this limestone matrix.

Item #17620 Dolomite 11.7x8.8x5.2 cm $45.00 Walker Brothers Quarry St. Catherines Ontario, Canada The top of this dolostone matrix shows concentric rings of creamy-pinkish, rhombohedra of dolomite. The rhombs are the curved type so typical of dolomite crystals from this area. A handsome specimen that stands perfectly for display. Excelent!	Item #18691 Marcasite 8.8x6.2x4.5 cm Largest Crystal Size: 2mm $35.00 Flamboro Quarry Wentworth County Ontario, Canada A great-looking, concave plate of marcasite crystals on crystallized dolostone matrix. The marcasite crystals are sharp with a slightly greenish-golden iridescence. A few small calcite and fluorite crystals here and there on the piece. Displays perfectly.
Item #18692 Marcasite 6.8x4.5x3.5 cm Largest Crystal Size: 5mm $35.00 Flamboro Quarry Wentworth County Ontario, Canada Lots of sharp marcasite crystals on this dolostone matrix. Some are bruised. Good locality piece that stands well for display.	Item #17639 Calcite 17.1x13.2x8.5 cm Largest Crystal Size: 19mm $55.00 Beemsville Ontario, Canada A larger, very displayable cluster-plate of calcite crystals. Needs help to stand like this. Looks great!	Item #16973 Calcite 5.3x4.2x1.8 cm Largest Crystal Size: 23mm $35.00 Lafarge Quarry Wentworth County Ontario, Canada A very nice small plate of smooth, lustrous calcite crystals on dolostone matrix. Nice looking and unusual.	Item #18900 Calcite 14.4x10.2x7.9 cm Largest Crystal Size: 23mm $40.00 Lafarge Quarry Wentworth co. Ontario, Canada The vug in this dark limestone matrix is lined with calcite crystals, some of which are larger and a more deep golden colour than the smaller ones. Nice looking!
Item #19775 Calcite 6.6x6.0x4.5 cm Largest Crystal Size: 24mm $55.00 Lafarge Quarry, (Dundas Quarry) Wentworth Co. Ontario, Canada A really nice spray of calcite crystals.

Item #19898 Gypsum 6.1x4.8x3.0 cm Largest Crystal Size: 22mm $35.00 Lincoln Quarry Beamsville Ontario, Canada A jumble of interlocking gypsum crystals cover the top of this gypsum matrix. A nice specimen of one of the less common minerals from that area. Displays very well.	Item #22000 Calcite, Baryte 8,6x7.0x3.2 cm Largest Crystal Size: 38mm $65.00 MacGregor Quarry Amhearstburg Ontario, Canada This specimen is a plate/cluster of calcite crystals showing scalenohedral habit. The crystals are white/creamy in the middle of the crystals and trend to gemmy orange closer to the termination. The calcite cryastals have a dusting of tiny groups of white, bladed, baryte crystals on their upper surfaces. Nice!	Item #24325 Calcite 11.3x5.4x5.7 cm Largest Crystal Size: 11mm $40.00 Beamsville Quarry Beamsville Ontario, Canada This attractive specimen shows light-golden curved scalenohedra of calcite across much of the front of it.

Item #25102 Calcite 4.2x3.6x3.5 cm Largest Crystal Size: 9mm $35.00 Flamboro Quarry Wentworth Co. Ontario, Canada Here we have two botryoidal calcite spheres butted up against each other, in a vug in dolomitic limestone matrix. The bigger ball of the two has a sharp calcite rhomb protruding from its side. The balls glow white under UV light. Also many tiny marcasite crystals present. A great example from this locality. DD	Item #25107 Calcite 3.6x4.3x3.1 cm Largest Crystal Size: 9mm $35.00 Flamboro Quarry Wentworth Co. Ontario, Canada This specimen shows a botryoidal calcite sphere in a sparkling vug in dolomitic limestone matrix. There are a couple of orangey sphalerite micro crystals near the calcite on the matrix as well. Glows white under UV light. A nice example from this locality. DD	Item #25108 Calcite, Sphalerite 3.8x3.5x2.3 cm Largest Crystal Size: 8mm $35.00 Flamboro Quarry Wentworth Co. Ontario, Canada This is a sweet botryoidal calcite sphere in a partial vug in dolomitic limestone matrix from the Flamboro Quarry. The ball has both a small sharp calcite rhomb protruding from its side and a sphalerite crystal on the top. Glows blue-white under UV light and the dolomite has a u/v yellow colouration. A striking example from this locality. DD	Item #26078 Calcite 5.5x4.4x2.8 cm Largest Crystal Size: 24mm $45.00 Lafarge Quarry Wentworth County Ontario, Canada A beautiful specimen of calcite scalenohedr on lomestone matrix.

Item #27961 Gilsonite 4.42.8x3.0 cm Largest Crystal Size: n/a $65.00 Steetley Quarry (Lafarge) Wentworth County Ontario, Canada Here is an interesting one. It is a glob of hard, hydrocarbon sitting in a vug of tiny calcite or dolomite crystals. The label says "gilsonite" and it may well be. I do not know what separated the various hydrocarbons like this from each other. Interesting and unique!
