Hey there, I’m Sebastian Naturski — Your Diamond Teacher. I launched this site nearly a decade ago when I was just a law student at Humboldt University of Berlin. What started as a quest to find the perfect engagement ring turned into a deep obsession with all things diamonds.

Back then, I was a clueless buyer trying to impress my girlfriend with the most stunning ring I could find. But the deeper I dove, the more I realized just how little most jewelers actually knew. Between sales pressure, vague advice, and misleading grading reports, it lit a fire in me to learn everything and share what I discovered. I eventually earned my GIA Diamond Essentials certification as part of that journey.
Since then, I’ve spent thousands of hours reading, reviewing diamonds, and helping people all over the world make smarter diamond decisions. What drives me is turning complex topics like fluorescence, crown angles, and clarity plots into something actually useful and fun to read.
Originally from Berlin, I now split my time between Germany and Medellín, Colombia, my second home for the past eight years. Medellín is where I dive deep into diamond research and hike the mountains with my Pomeranian sidekick, Odin. Berlin keeps me grounded in Europe’s diamond market and closer to the heart of industry trends. Together, both cities fuel the global perspective I bring to this site.

In 2025, I’ve been putting even more energy into refining this site and making sure everything reflects what I’ve learned over the years. Lab-grown diamonds, in particular, have sparked a wave of change in the industry. The quality is rising fast. Prices are dropping. And the questions people are asking are getting sharper and more important.
Sometimes I think about it like this: If lab-grown meat ever reached a point where you could enjoy authentic Kobe beef for just ten dollars, with identical taste and quality, everyone would celebrate. No one would say it is less valuable because it was not raised in Japan for three years. Taste, nutrition, and affordability would take the lead.
So why is it different with lab-grown diamonds?
They’re chemically and optically identical to earth-mined diamonds and far more affordable. But deep down, most people still wrestle with a feeling: “Is it special enough?” “Is it worth gifting?” “Will it hold value?”
I get it. I’ve had those same thoughts. Part of what once made a diamond so meaningful was its rarity, the idea that it was forged in the earth over billions of years, and that you were giving someone something precious and permanent.
But here’s the truth: even earth-mined diamonds are no longer what they used to be. Prices have dropped hard. Resale values are disappointing. And the illusion of scarcity? It’s been quietly unraveling for years.
So what’s the smart move?
I’m not here to push one side. I’m here to give you the clearest, most honest picture possible. For some people, lab-grown diamonds are a no-brainer. They get a stunning, high-quality stone without breaking the bank. For others, the emotional weight of a natural diamond still matters. Both are valid. What matters is that *you* know what you’re choosing and why.

If you have any questions, whether you’re looking to propose, upgrade a ring, or you’re just curious, feel free to reach out via my contact form. I’m always happy to help.
Thanks for visiting Your Diamond Teacher. Let’s make you a smart diamond buyer and confident while doing it.
