Introduction

Peru can be an exciting place for rock and gem collectors.

The famous blue and pink opals and pyrites are exciting finds, but you may also find impressive veins of epidote, apatite, leopard stone and serpentinite. 

Mining in Peru has been subject to a lot of legislation. Gold mining has had devastating effects on the rain forest.

Some types of mining have been completely banned. 

There are many large and small exporters of Peruvian gems, minerals and rocks and many of these stunning stones are available through these vendors. 

Fossils are common targets for collectors in Peru, be sure to hire an experienced trustworthy guide when you go fossil hunting. 

Blue & Pink Opal

The most famous gemstones from Peru are the Blue and Pink Opal.

These unique stones are a rare color of opal that can be found in the Lily Mine, Pisco Umay, Ica Peru.

These stones were first found during copper mining in the country in 1993. 

These stones fluoresce under black light and can sometimes be found washed down the Andes in river beds. 

There are two classifications of Opal; common opal and precious opal.

Precious opal has a variety of colors and tones and forms from microscopic crystal spheres. 

Common opal can have some milky color variation but lacks the interplay of colors in precious opal. 

The blue and pink opals found in Peru are common opals by this classification, but the blue and pink colors are very rare. 

This classification of common makes the beautiful stones affordable, but still rare and beautiful. 

Peruvian Opal is some of the most beautiful in the world and it is surprisingly affordable.

The stone can be purchased tumbled, as beads or as raw stones. 

Serpentinite 

Serpentinite is named after its snake-like appearance. The stone is green and appears to have scales.

This fine gained smooth stone has a greasy luster and a deep green color. 

These stones are often made of olivine and they have white veining in a folding pattern.  

Serpentinite is not a rare stone, and is easily recognizable by the green color and white veins. 

Serpentinite has been found in Huancayo, Peru which is located at the foot of the Andes Mountain range.  

Pyrite

Pyrite is sometimes called fool’s gold because it has the same brassy color and bright luster as gold. 

Pyrite forms crystals with lines or striations on the crystals.

The crystals can be cubic and often form in quartz and coal deposits. 

There have been many types of pyrite specimens found in the Huanzala Mines in central Peru. 

The formations are a collection of crystals that form a large pyrite deposit. 

Epidote 

Epidote is a deep olive green semi transparent crystal that has been found in Peru. 

The beautiful crystals have a long prismatic habit. 

The crystals look like a bundle of needlelike dark green crystals. 

The crystals can be found in parts of the Andes mountain and they generally form in veins, pay close attention to any dark green areas in rocks and explore the surrounding area. 

This gem collector was able to uncover an enormous vein in Peru.
