Good-looking specimen of this rare titanium silicate mineral!	Item #21961 Ussingite 4.7x4.3x3.2 cm Largest Crystal Size: n/a $65.00 Mt. Punkurauj Chibiny Massif, Kola Peninsula Russia A fragment of massive ussingite ranging from light mauve to purple. Rich!

Some were in contact with the other side of the seam but many are fully formed. Nice!	Item #21939 Tyuyamunite, Calcite 6.0x4.4x4.0 cm Largest Crystal Size: n/a $65.00 Valencia County New Mexico, USA The top of this matrix is totally covered with bright yellow tyuyamunite which is in turn largely covered with small, clear, well formed calcite crystals.

This mineralization was claimed and looked at as a source of ore-grade kyanite rock 50 years or so ago but found to be too low grade overall. This specimens looks great and is a nice example of this type of metamorphism.
Item #21895 Vlasovite, Gittinsite, Eudialyte 5.8x3.3x1.8 cm Largest Crystal Size: v-20mm $75.00 Kipawa Complex Abitibi-Temiscamingue Quebec, Canada Quite an exotic association of rare minerals here! The matrix is red-purple eudialyte that has crystals of glassy vlasovite embedded in it. The vlasovite, in turn, has been altered around the edges and in cross-cutting fractures to white gittinsite. So all the white you see in this specimen is gittinsite. Rare!	Item #21893 Eudialyte 8.1x6.2x2.4 cm Largest Crystal Size: n/a $40.00 Kipawa Complex Abitibi-Temiscamingue Quebec, Canada An almost solid fragment of eudialyte from the famous alkaline rock complex at Kipawa. Rich!

In this case, sharp, white, well formed heulandite crystals have formed on much older pyroxene crystals. Nice example!	Item #21891 Stilbite, Heulandite, Pyroxene 7.0x3.4x2.4 cm Largest Crystal Size: s-15mm, h-3mm $45.00 Maniwaki Quebec, Canada Interestingly, very well formed zeolites are sometimes found in very old Grenville openings that have been subjected to low temperature hydrothermal alteration. Here is a good example. The poor pyroxene crystals that form the matrix for very well formed stilbite and heulandite cryustals. The stilbite crystals are present as classic, divergent clusters with an orange-brown colouration. The heulandites are present as well formed crystals with pearly luster on the pinacoids so typical of heulandite. Very nice example!
Item #21890 Zoisite, (Thulite) 3.7x2.4x1.0 cm Largest Crystal Size: 13mm $35.00 Remigny Quebec, Canada Pink zoisite crystals associated with creamy white armenite in white matrix in this unusual specimen.

Pure-white, very long, acicular crystals of pectolite are scattered and intergrown with very light green diopside crystals on rhodingite matrix. There are also some very sharp, colourless prehnite crystals, to 5mm or so, embedded amongst the diopside crystals. The piece is delicate but I think I can package it well to survive to post. Looks great!	Item #21877 Forsterite, Spinel 6.9x4.8x3.2 cm Largest Crystal Size: f-17mm, sp-8.5mm $75.00 Parker Mine Notre Dame du Laus Quebec, Canada The top of this specimen shows a very sharp, tabular forsterite crystal and a couple of sharp, octahedral spinel crystals. There are other forsterite and spinel crystals on the top and bottom of this piece, partially etched out of calcite. Excellent!	Item #21875 Scolecite. Stilbite 9.2x5.4x2.1 cm Largest Crystal Size: n/a $75.00 Lake Asbestos Mine (Mine Lac d'Amiante) Black Lake Quebec, Canada Hemispheres of very white acicular scolecite are thickly scattered on light beige stilbite crystal terminations.

Rare from THE locality!	Item #21869 Pectolite 8.1x5.4x3.4 cm Largest Crystal Size: 12mm $65.00 Lake Asbestos Mine Black Lake Quebec, Canada This specimen shows a vein or seam of pectolite. The pectolite is composed of radiating aggregates of pure white acicular pectolite. An unusual and excellent specimen from this prolific, long closed asbestos mine.	Item #21868 Scolecite 7.5x5.7x4.0 cm Largest Crystal Size: n/a $65.00 Lake Asbestos Mine Black Lake Quebec, Canada The top of this specimen is largely covered with botryoidal scolecite that has formed over stilbite crystals, none of which are visible, except by viewing the side of the piece. The scolecite is composed of tiny, radiating, acicular crystals that form the botryoids. The specimen is actually pure, creamy white not the grayish look caused by the lighting in the pictures. Very nice specimen from one of the "other" large asbestos mines in southern Quebec, near the more famous Jeffrey Mine.
