I will tell you what the stone is made of and how to tell it from the thing being sold as it. What you then do with the stone is your own business, and I am not going to sneer at it.

How Round Brilliant Facets Create Light and Sparkle

February 12, 2025 by Dagny Solheim
The facets of a round brilliant and what each one does.

I spent six years hunched over a bench in a grading lab, staring through a loupe until my eyes felt like they were filled with sand. I’ve seen enough “miracle stones” to know that most people are sold a fantasy of magic rather than geometry. When you’re looking at a diamond, you aren’t looking at … Read more

Step Cuts and Brilliant Cuts Differ in Sparkle and Style

February 10, 2025 by Dagny Solheim
Step cuts and brilliant cuts compared.

I remember sitting in a cramped grading lab in Bergen, squinting through a loupe at a tray of stones that all looked, at first glance, like nothing more than little sparks of light. Most people walk into a jeweler’s shop expecting a certain kind of magic, only to find themselves paralyzed by the choice between … Read more

Why the Round Brilliant Cut Became the Industry Standard

February 9, 2025 by Dagny Solheim
How the round brilliant became the default shape.

I spent six years hunched over a bench in a grading lab, staring through a loupe until my eyes felt like they were filled with sand. I’ve seen enough stones to know that the industry loves to wrap simple things in layers of expensive-sounding nonsense. People will try to tell you that the round brilliant … Read more

February 6, 2025 by Dagny Solheim
Choosing a setting for a soft stone.

I remember sitting in the grading lab back in Bergen, staring through a loupe at an opal that looked like a spilled bucket of oil on a wet pier. It was breathtaking, but it was also incredibly fragile. A few months later, I saw a client walk in with a beautiful piece of morganite that … Read more

How Zircon Differs From Cubic Zirconia

January 29, 2025 by Dagny Solheim
Zircon and how it differs from cubic zirconia.

I remember sitting in a dim grading lab in Bergen, squinting through a loupe until my eyes ached, staring at a tray of stones that looked identical to the naked eye. A client had brought in a ring, convinced they’d found a rare treasure, only for me to realize they were holding a piece of … Read more

Spinel Was Often Mistaken for Ruby Throughout History

January 28, 2025 by Dagny Solheim
Spinel and the centuries it spent mistaken for ruby.

I remember sitting in a cramped, fluorescent-lit lab in Bergen, squinting through a loupe until my eyes ached, staring at a stone that looked like a drop of blood caught in a tide pool. It had that deep, saturated red—the kind of color you only see when a pebble is completely submerged in seawater—and the … Read more

Tanzanite Only Comes From One Small Location in Africa

January 26, 2025 by Dagny Solheim
Tanzanite and why it comes from one place only.

I spent six years hunched over a microscope in a grading lab, and if there is one thing that gets under my skin, it’s the way people wrap gemstones in layers of expensive, mystical nonsense. You’ll see shops charging a premium for “spiritual energy” when all you really need to know is the chemistry and … Read more
