Photo shows a white crystal of laumontite on calcite crystals. Width of view 6mm. Stack of 65 images. Click on the image below for a higher resolution version.
Found in driveway gravel that was known to have come from the quarry. White flat-laying crystals of laumontite that fluoresces bluish-purple (best under medium wave) with small hematite crystals. Width of view 9mm and stack of 30 images (fluorescent image). Width of view 6mm and stack of 30 images (hematite)....
White (dehydrating) laumontite with colourless chabazite and stilbite. The laumontite is very unstable, and unfortunately not only breaks down itself, but also the matrix. Photo widths 6mm. Stack of 45 images (laumontite) and 65 images (chabazite). Click on the images below for a higher resolution version.

From Level 16, NBHC. See https://rruff.info/uploads/CM46_73.pdf. Laumontite fluoresces blue under LWUV. Laumontite photo: First image: Width of view 6mm. Stack of 80 images. Second image: Width of view 9mm. Stack of 60 images. Click on the images below for a higher resolution version.
Wairakite is one of the rarer zeolite species. It’s typically found around hot springs and forms white dodecahedral crystals similar to analcime. In this case, the white wairakite is completely replacing the elongated, stick-like crystals of another zeolite, laumontite. 35x28x12mm. Width of view 9mm. Stack of 40 images.
Green prismatic epidote with apparent paler tips, white prismatic flattened crystals of laumontite, and green platelets of pumpellyite. Small colourless quartz crystals. Width 9mm, stack of 78 images (epidote). Width 4.5mm, stack of 30 images (laumontite). Ex Bernie and Margaret Day Collection.
Small pyrite cubes with minor octahedral corners, colourless to orange stellerite crystals and white laumontite. Height 4.5mm. Stack of 30 images. Ex Jo Price Collection.
Colourless stilbite crystals on black bitumen. Laumontite intermingled with bitumen. Apophyllite (in second photo) and unknown hexagonal or pseudohexagonal (in main photo) crystals in another cavity. Maybe just apophyllite? Photo width 3.25mm. The calcite is fluorescent.
Single quite large apophyllite crystal with minor white laumontite and greenish pumpellyite.
Blocky opaque apophyllite with minor colourless stilbite and white laumontite on green prehnite. 65x45x10mm. Ex Joe Cilen (7403). Ex Eugene Carmichael (562). Hydroxyapophyllite-(K), prehnite, stilbite, laumontite, from the Fairfax quarry (Centreville Quarry; Sisslers Quarry), Centreville, Culpeper Basin, Fairfax Co., Virginia, USA.
