1.4" Green Olivine Peridot Crystal Cluster with Magnetite - Pakistan

This is a wonderful, 1.4" long, green olivine peridot crystal cluster with nice terminations, collected from Kaghan Valley in the Khyber Pakhtunkhwa Province of Pakistan. The dark portions of this specimen can be attributed to needle-like ludwigite inclusions and the dark-grey crystal along one edge is magnetite. The magnetite has excellent magnetic properties!

This specimen has been mounted to an acrylic display base with mineral tack.

Peridot is a magnesium iron silicate mineral with the basic chemical formula Mg2SiO4. It is a gem variety of the mineral forsterite, and ranges between yellow, olive, to brownish green, much of the time depending on amount of iron present during formation. Dark, olive green colored peridot gems are typically the most sought after.

Peridot was originally named as topaz, and was used for a variety of reasons, whether it be during the Crusades as a way to adorn religious objects, or was even thought by many to posses medicinal powers. For unknown reasons, during the 18th century the original name was removed and given to the mineral that most know as topaz, today. Peridot has remained pertinent throughout the years, being named the August birthstone.

Specimens from the Kaghan Valley of Pakistan are highly sought after by collectors for their color, quality and in some cases, their inclusions. These peridot crystals are often found in association with magnetite and calcite, and will occasionally contain ludwigite inclusions.

Many gem quality specimens were originally in basalt nodules in the earths mantle, and were fragmented and brought to the surface by volcanic activity.
