pyrope

The color of pyrope varies from deep red to black.

The mineral pyrope is a member of the garnet group.

Unable to risk her, Pyrope becomes seriously injured before killing all the guards.

Iron and manganese substitute for the magnesium in the pyrope structure.

The semi-precious stone rhodolite is a garnet of 70% pyrope composition.

Pyrope is an indicator mineral for high-pressure rocks.

Care should be taken when using these properties as many of those listed have been determined from synthetically grown, pure-composition pyrope.

Another intriguing find is the blue color-changing garnets from Madagascar, a pyrope spessartine mix.

Pyrope is common in peridotite xenoliths from kimberlite pipes, some of which are diamond-bearing.

Almandine is one end-member of a mineral solid solution series, with the other end member being the garnet pyrope.

Rhodolite is a varietal name for rose-pink to red mineral pyrope, a species in the garnet group.

The garnets from mantle-derived rocks, peridotites, and eclogites commonly contain a pyrope variety.

By 1982, Gurney had established that the kimberlite pyrope garnet "G10" was critical to diamond discovery.

More specifically, this is probably the more common Pyrope Garnet based upon color and availability, which is used in the member's badge.

Others, such as pyrope's high specific gravity, may be of little use when studying a small crystal embedded in a matrix of other silicate minerals.

In these cases, mineral association with other mafic and ultramafic minerals may be the best indication that the garnet you are studying is pyrope.

In petrographic thin section, the most distinguishing features of pyrope are those shared with the other common garnets: high relief and isotropy.

The mineral assemblage is greater than 90% olivine, with minor amounts of other minerals such as pyroxene, chromite and pyrope.

For the bird sometimes placed in the monotypic genus Pyrope, see Fire-eyed Diucon.

In hand specimen, pyrope is very tricky to distinguish from almandine, however it is likely to display fewer flaws and inclusions.

The lack of cleavage, commonly euhedral crystal morphology, and mineral associations should also be used in identification of pyrope under the microscope.

Second row: a carbuncle (a red almandine, pyrope), a sapphire, and a jasper (usually red, brown or yellow chalcedony).

Latula Pyrope (Fictional Character)

Garnets tend to be less strongly coloured than other silicate minerals in thin section, although pyrope may show a pale pinkish-purple hue in plane-polarized light.

A variety of pyrope from Macon County, North Carolina is a violet-red shade and has been called rhodolite, Greek for "rose".
