Why our products are special & when we purchase them, we open up awareness of ethically pure crystals

Highest Quality & “Ethical Mining”
This product comes from this ethically cleanest source & highest quality production.
We fight together for ethical minerals

We support a company that was founded by a friend who worked at Greenpeace for 30 years and has now founded a company for the clean mining of minerals.

We do not sell cheap and unethical large-scale production from China & India
In this world, many minerals are mined illegally, without protection, bloodily and corruptly, the conditions are often miserable from the mining to the grinding process, there is a lot of exploitation and the profits often go to large corporations. Workers are poorly protected during mining, if it is even legal & the pay is a sad joke.

With the cooperation of our company in Peru, we make sure to know: -Where our minerals come from, who mined them & under what conditions, who ground the product & how it was processed, that it does not have a long supply chain & we end up with a receive a specially tailored, high-quality product that is unique on the market.

We hope you have a lot of fun with this product, it comes from ethically pure production and the minerals were found and processed directly in Peru.


About Red River Sunset from our partner:

"In 2019, when we were testing new materials for our jewelry production, we came across this thin dendritic layer in a rock. Looking at the rock and other samples from the surrounding area, we realized we had something extraordinary on our hands:

A constant pattern resembling a horizon of trees and bushes against white, snow-capped mountains under a blood-red sunset sky.

We named it “Red River Sunset”® in honor of the unique red river near Cusco Peru.

But this stone had something even more exciting:

Other dendritic stones exhibit irregular dendritic patterns that are difficult to predict, making it difficult to plan large-scale jewelry production based on such a material.

However, here we have a vein that crosses the rock with a consistent color pattern. You can cut this vein and panel after panel will show the same color pattern. This makes it possible to plan large jewelry editions that receive individual but very similar cabuchons. Something we haven't seen before with dendritic stones.

After testing this material in the lab, we now know that Red River Sunset® is a bicolor carbonate with a predominance of calcite. The red layer is richer in iron, although the highest percentage was found in testing at just 0.89%. However, iron is a strong coloring agent.

According to tests, this material is most likely travertine. Travertine is a form of terrestrial limestone that is deposited around mineral springs, particularly hot springs.

Fresh travertine varies greatly in its porosity, from around 10% to 70%. However, Red River Sunset® has a comparatively low porosity, indicating that it is a very old travertine. Such ancient travertines can have porosity as low as 2% due to the crystallization of secondary calcite in the original pore spaces. It also indicates that this travertine was formed around a hot spring rather than a cold spring. Finally, given that the material lacks magnesium, it is most likely that it was formed in fresh water and not sea water.!
