About Noble Facets.
Tatjana Li
Founder & CEO
I've spent nearly two decades in the colored gemstone trade and jewellery industry,
primarily in GreaterChina—the world's most demanding market.

I've evaluated thousands of stones, built relationships with suppliers across four continents,
and helped countless clients navigate the complexity of colored gemstones.

After returning to Germany, I established Nobel Facets in Idar-Oberstein
—the historic heart of European gemstone cutting. It's a deliberate choice.

This region has maintained uncompromising standards for over 500 years.
That heritage shapes how I work.

My approach is simple: combine deep gemological expertise with business acumen,
deliver objective advice without inventory conflicts,
and teach clients to build their own capabilities rather than keeping them dependent.

I succeed when you succeed—not when I sell you something.

Our Philosophy
We work hard every day to make
our clients' lives easier and their businesses succeed.
  • Objectivity
    We don't carry inventory beyond our Triple L collection. This matters because it means we have no incentive to push specific stones. When we recommend a purchase—or advise against one—it's based purely on whether it serves your interests. This objectivity is fundamental to how we operate.
  • Education-First Approach
    Our goal is your long-term independence, not ongoing dependency. We teach you to evaluate colored gemstones, understand treatments, and assess fair pricing. Yes, this means some clients eventually need us less. That's the point. Building your team's capabilities is part of our service—and it's why relationships last.
  • Transparency
    Commissions are disclosed. Pricing rationale is explained. Treatment disclosures are emphasised and documented. In a market often characterised by opacity, we operate differently. You should always know exactly what you're paying for and why we recommend it.
  • Long-term Partnerships
    We optimise for relationships measured in years, not individual transactions. This
    shapes every recommendation. We'll tell you when to walk away from a deal. We'll prevent costly mistakes even when it means less short-term revenue for us. Because clients who succeed come back—and refer others.

Strategic location for serving German and European markets
Idar-Oberstein isn't just where we work—it's a statement of standards.

This small region in the Hunsrück mountains has been the centre of European gemstone cutting for over 500 years. The techniques developed here are still considered the gold standard. The master cutters who practice their craft in these workshops represent generations of accumulated knowledge.

Being based here means access to these craftsmen. It means stones can be recut or custom-cut to maximise their potential. It means working within a community that takes precision and quality seriously.
