Our Story

about us

Zaréte is dedicated to helping you preserve, and increase, your value with Diamond-Sparkle Crystalline Osmium™.

We are the Osmium Institute for the state of Texas granted by the German Osmium Institut​e​, who holds the license for our sparkling osmium.

We have always loved helping people. In fact, we are a doctor and nurse. We were co-founders in a successful medical device startup that sold to a large, international medical device company. Now, instead of helping patients, we want to help you.

Our Future Goal

We want to lead in innovation & Technology

My wife is truly special, and when we got engaged I let her pick a ring she felt most reflected her uniqueness, a beautiful diamond ring.

While that diamond ring remains beautiful to this day, it is worth no
more today than it was a few decades ago when I bought it. That is because diamonds are not rare anymore because they can now be manufactured from commonplace carbon.

Why Diamond-Sparkle Crystalline Osmium™ ?

Compared to Diamond-Sparkle Crystalline Osmium™ , diamonds are not rare. It takes over 10,000 tons of platinum ore to create a single ounce of osmium. Diamonds, by contrast, are made of carbon, which is among the most abundant elements in the universe. The process to create Diamond-Sparkle Crystalline Osmium™ makes it even rarer than plain osmium.

Diamond-Sparkle Crystalline Osmium™ is my wife’s new best friend! Our mission is to help you understand why it can be yours too.

You can see the steady increase in value, per gram, of Diamond-Sparkle Crystalline Osmium™ since its inception in 2017 here: https://www.osmium-preis.com/en/price/usd/x/daily/
