CLINOCHLORE
Specimen cnc-4

Dims: 4.4x3.1x0.3" (11.2x7.9x0.7 cm)

Wt: 3.0 oz. (87.2g)

Korshunovka, Siberia, Russia

This slab (polished on one side) is a very nice hand specimen of clinochlore. Most of the mineral is in the form of a radial fibrous growth which exhibits a chatoyancy on the polished surface. Towards the center of the specimen, there is an intergrowth of thousands of small crystals (1mm-3mm in length), most of which look like books of foliated crystals. However, some of the crystals are a beautiful, transparent, emerald green which look quite lovely under a loupe. Unfortunately, they are too small to be seen by the naked eye, other than as a green sparkle when the light hits them just right.

Dims: 2.89x2.07x1.12" (7.34x5.26x2.84cm)

Korshunovka, Siberia, Russia

The clinochlore in this specimen is mostly a light silvery green color, organized in intergrown foliated clusters. There are also patches of purplish-red mineral, whose crystals look exactly the same except for color, and which I believe to be more clinochlore (which would make it the kaemmererite variety). One face of the specimen has been cut flat and polished to a high luster; the remainder is natural fracture surface.

Dims: 1.70x1.15x1.15" (4.33x2.93x2.93cm)

Wt: 1.55oz. (44.0g)

Korshunovka, Siberia, Russia

This clinochlore specimen is mostly composed of light metalic-green crystals in books of foliated crystals. They appear opaque, and there are areas where a radial growth form is visible. Some areas have a reddish tint as a surface coating (perhaps a weathering). One side of the specimen has been polished to a high luster.

Dims: 2.03x1.22x1.01" (5.16x3.09x2.57cm)

Wt: 1.34oz (38.0g)

Korshunovka, Siberia, Russia

This clinochlore specimen, like others from the same locale, consists of silvery-green (and occasionally maroon) foliated crystals intergrown in an opaque mass that has a pearly luster. One side of the specimen has been cut and polished to a high luster, and which reveals (when held to a bright light) that the clinochlore is actually translucent. The images do not properly show the light green color.

Korshunovka, Siberia, Russia

This slab is a cross section of a formation of clinochlore in which a core of massive clinochlore is covered with crystals of clinochlore. The crystals are polished and show a layered radial growth habit with layers of different lightness yet all with the same green hue. The crystals are opaque and display a silky luster.
