Description
Rough Peridot Crystal Set – Natural Olivine Mineral from Pakistan
This listing features six natural rough Peridot crystals from Pakistan, presented as a small mineral collection of raw olivine specimens. These crystals display the characteristic olive-green colour and natural crystal forms that make peridot one of the most recognisable magnesium iron silicate minerals.
Each crystal in the set has been carefully selected for colour, structure, and mineral quality, preserving the natural surfaces and geological features formed during crystal growth. The photographs provided in the listing show the exact six Peridot crystals you will receive, allowing collectors and buyers to view the natural crystal forms, colour intensity, and mineral textures before purchase.
For precise sizing and scale, please refer to the measurements shown in the listing photographs. This set includes a Certificate of Authenticity lifetime guarantee generic card, confirming the crystals are genuine mineral specimens.
Mineral Species and Geological Classification
Peridot is the gem-quality variety of the mineral olivine, a magnesium iron silicate with the chemical formula (Mg,Fe)₂SiO₄. Olivine belongs to the nesosilicate mineral group, which is characterised by isolated silica tetrahedra within the crystal structure.
The mineral crystallises in the orthorhombic crystal system, typically forming short prismatic or granular crystals. Olivine is a major rock-forming mineral in the Earth’s mantle and is commonly found in ultramafic and mafic igneous rocks.
Peridot crystals often form in basaltic volcanic environments, where magma rising from deep within the Earth brings mantle-derived minerals closer to the surface.
Colour, Crystal Structure and Physical Properties
Peridot is well known for its distinctive olive-green to yellow-green colour, which is caused by the presence of iron within the crystal structure. Unlike many gemstones, the colour of peridot is intrinsic to the mineral and does not depend on trace impurities.
Natural rough crystals may show transparent to translucent areas, natural crystal faces, fractures, or internal inclusions formed during growth within volcanic environments.
Typical mineral properties include:
• Mineral Species: Olivine (Peridot variety)
• Chemical Formula: (Mg,Fe)₂SiO₄
• Mineral Group: Nesosilicate
• Crystal System: Orthorhombic
• Colour: Olive green to yellow-green
• Transparency: Transparent to translucent
• Lustre: Vitreous
• Mohs Hardness: Approximately 6.5–7
Many natural peridot crystals contain small internal features sometimes known as “lily pad” inclusions, which are characteristic internal fractures commonly observed in this mineral.
Geological Formation and Occurrence
Peridot forms in high-temperature geological environments deep within the Earth’s mantle. When mantle material rises through volcanic activity, olivine crystals may become incorporated into magma and transported to the surface within basaltic lava flows.
Peridot crystals may also occur in peridotite rocks, which are ultramafic mantle rocks composed primarily of olivine.
The deposits in Pakistan, particularly in mountainous regions where tectonic processes expose deep geological formations, are known for producing peridot crystals with strong green colour and well-defined crystal structures.
Associated minerals commonly found with peridot in geological environments include:
• Pyroxene
• Spinel
• Chromite
• Garnet in mantle-derived rocks
These minerals occur together in ultramafic rock formations formed under high temperature and pressure conditions.
Rough Crystal Form and Collecting Appeal
Rough Peridot crystals are appreciated by collectors for their natural crystal structures and vibrant green colour, which contrasts with the darker matrix minerals often found in ultramafic rocks.
Because these crystals remain in their natural state, they preserve the original crystal faces, fractures, and geological textures created during formation.
Sets of rough peridot crystals are popular for:
• Mineral collections
• Educational geological specimens
• Lapidary study or gemstone cutting reference
• Natural stone displays
Each crystal forms under unique geological conditions, meaning every specimen displays its own natural shape, colour intensity, and internal structure.
In some cultural traditions, peridot has been traditionally associated with symbolic meanings connected to growth or renewal, though such interpretations are cultural perspectives rather than scientifically established properties.
