Mineral Galleries | Gillardite
Gillardite (formerly IMA 2006-041) is a new mineral species from the 132 North deposit, Widgiemooltha, Western Australia. Gillardite has the idealized formula of Cu3NiCl2(OH)6, corresponding to a nickel substituted analog of paratacamite. Originally, Nickel et al. (1994) described this material) as a nickel bearing paratacamite. Later determinations of the crystal structures of paratacamite-like phases show that the Ni occupies a specific place in the crystal structure, thus qualifying this mineral as a new specie (Colchester et al. 2007).

MS0211 - Gillardite
Date: April 23rd, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Small cabinet, 5.6 by 4.3 by 2 cm
$300 - Order Form
This specimen has a large coverage area of 8 cm2 of dark green gillardite. The gillardite forms a crust of interlocking rhomobohedral crystals. Near the edges of the coverage, some nice areas allow attractive photomicrographs. This is an excellent specimen of the new mineral. One of the authors of the Mineralogy of Arizona, Ray Grant, collected this specimen in 2007.
MS0212 - Gillardite
Date: April 23rd, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Miniature, 5.4 by 2.2 by 2.0 cm
$160 - Order Form
This specimen has a large coverage area of 6 cm2 of dark green gillardite. Like many of the specimens, a later veneer of gypsum has formed on the surface of the specimen. This causes an attractive satin luster for the crystalline surface. This specimen has attractive botryoidal gaspéite to contrast the dark green gillardite. One of the authors of the Mineralogy of Arizona, Ray Grant, collected this specimen in 2007.
MS0213 - Gillardite
Date: April 23rd, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Miniature, 3.9 by 2.7 by 1.0 cm
$160 - Order Form
Gillardite has formed tight groups of rhombohedral crystals on gaspéite and gossan matrix. The separation of the aggregrate provide much opportunity for attractive photomicrography. This is an excellent specimen of the new mineral. With minor gypsum.
MS0214 - Gillardite
Date: April 23rd, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Small cabinet, 8.2 by 4.3 by 2.7 cm
$400 - Order Form
This specimen has a large coverage area of 15-16 cm2 of dark green gillardite. Like many of the specimens, a later veneer of gypsum crystals has formed on the surface, causing the specimen to shimmer in a satiny patchwork.
In addition to botryoidal gaspéite, another nickel mineral is present, possibly nullaginite. An author of the Mineralogy of Arizona, Ray Grant, collected this specimen in 2007.
MS0215 - Gillardite
Date: April 23rd, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Miniature, 4.9 by 2.5 by 1.4 cm
$120 - Order Form
Gillardite has formed tight groups of dark green rhombohedral crystals on gaspéite and gossan matrix. The structure would trim into two excellent thumbnail specimens. This specimen has an above average crystal size. This is an excellent specimen of the new mineral. With minor gypsum.
MS0216 - Gillardite
Date: April 23rd, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Small cabinet, 6.5 by 5.1 by 2.9 cm
$200 - Order Form
This is a rather large matrix specimen of gillardite, containing many groups of dark green gillardite crystals, contrasted with light green gaspéite on gossan matrix. This specimen could trim into 2-3 nice miniatures or perhaps 5-6 thumbnail specimens. This specimen has large crystals of gillardite. The separation of the aggregrate provide much opportunity for attractive photomicrography. Although randomly scattered over the matrix, there is a considerable amount of gillardite present. With minor gypsum.
MS0217 - Gillardite
Date: April 13th, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Miniature, 4.0 by 2.8 by 2.3 cm
$20 - Order Form
This specimen is a section of a gaspéite vein, with gypsum on its sides. Under the gypsum layers on both sides of the specimen, gillardite has formed flattened aggregates to 2 mm. This specimen has a considerable amount of fine botryoidal gaspéite. One of the authors of the Mineralogy of Arizona, Ray Grant, collected this specimen in 2007.
MS0218 - Gillardite
Date: April 23rd, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Miniature, 2.9 by 2.9 by 2.1 cm

This specimen is a section of a gaspéite vein, with gypsum on its sides. Under the gypsum layers on both sides of the specimen, gillardite has formed flattened aggregates to 2 mm. This specimen has a considerable amount of fine botryoidal gaspéite. One of the authors of the Mineralogy of Arizona, Ray Grant, collected this specimen in 2007.
MS0219 - Gillardite
Date: April 23rd, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Miniature, 4.2 by 2.8 by 2.7 cm
$20 - Order Form
This specimen is a section of a gaspéite vein with a pocket of gypsum crystals. This specimen contains only a spot of gillardite, which seems to float in gypsum. A nice micromount. This is a bargain specimen, being an attractive micromount of a brand new mineral species. One of the authors of the Mineralogy of Arizona, Ray Grant, collected this specimen in 2007.
MS0220 - Gillardite
Date: April 23rd, 2008Gillardite with Gaspéite
132 North deposit, Widgiemooltha, Western Australia, Australia
Miniature, 3.6 by 2.9 by 2.7 cm
