Cluster of fan-shaped epidote crystals (SCESP005)

Description

Cluster of fan-shaped epidote crystals (SCESP005)

A beautiful small-cabinet-sized cluster of fan-shaped epidote crystals (SCESP005). This specimen consists of interpenetrating and randomly oriented, fan-like clusters of epidote crystals. Fan-shaped crystal clusters in epidote are rare. There are only a few places around the world that produce fan-shaped crystals. This one comes from Gemrock Peru´s crystal mining project in Lima province, Peru.

Small-cabinet size: 69 x 58 x 34 mm.

Weight: 129 gr

Origin: Peru, Lima Province, Gemrock crystal mining operation

Gemrocks mining for fan-shaped epidote crystal cluster

Epidote is a silicate that contains the elements Ca, Fe, Al, Si, O, and H. The area in Lima province where Gemrock Peru operates its first crystal mining operation is a skarn area. Epidote is a common mineral in skarn areas. Most skarns do form when a magma body intrudes carbonate rocks such as limestone, dolomite stone, or marble. This leads to contact metamorphism. Under those circumstances, the magma releases water as it cools. As a result, the water moves through the surrounding rock. It flows or diffuses through pore spaces, fractures, and even the mineral grains that make up the rock. These acidic waters are superheated and supersaturated with dissolved metal ions, especially calcium and silicon. Consequently, as it invades carbonate rock, the hot, acidic, metal-laden water becomes a major agent of change. It dissolves, replaces, recrystallizes, and alters minerals in the rock.

Consequently, this leads to an incredible variety of rare mineral combinations and unusual crystal growth forms.

About fan-shaped epidote crystals

Well-developed crystals of epidote are normally crystallizing in the monoclinic system: they are commonly prismatic in habit, the direction of elongation being perpendicular to the single plane of symmetry. The often twinned crystals commonly have deeply striated faces. In the case of our mining area epidote forms very rare fan-shaped layers of crystals. To date, one of the few locations for fan-shaped crystals was Pakistan.

Many of the characteristics of the mineral vary with the amount of iron present, for instance, the color, the optical constants, and the specific gravity. The color is green, grey, brown, or nearly black, but usually a characteristic shade of yellowish-green or pistachio-green. Epidote displays strong pleochroism (or iridescence), which means their optical properties vary with the direction of light. The direction of the electric field determines the polarization of light, and crystals will respond in different ways if this angle is changed.

 

Choose the CARBON-POSITIVE PRICE:

Buy this crystal free of environmental impacts. Help improve the environment:

Gemrock Peru is a global leader spearheading sustainability and environmental conservation in the crystal and gemstone industry. Furthermore, we are now offering you a unique opportunity to take part in our effort. Do eliminate the carbon footprint of your crystal. And then do even better: become carbon-positive. Here is how it works: If you buy this crystal by choosing the “Carbon Positive Price” we will add 1.5 cents per USD to your crystal. We are going to use this additional amount in order to plant trees in a reforestation project in the Peruvian cloud forest. As a result, we do neutralize your crystals’ carbon footprint. Furthermore, you are helping to restore previously destroyed rainforests.

In addition to this, we will match your support. We will reward your conscious act by matching your support with the same amount. This way we are doubling the donation. Therefore we are creating a carbon-positive product that removes more carbon from the atmosphere than it adds to it.

With Gemrock Peru your crystal products have been ethically mined and produced and are environmentally friendly. Also, read our 2021 Sustainability Report.
