How Single Crystals Create Beautiful Bi Colour Gemstones

October 7, 2025 by Dagny Solheim
Bi colour gemstones and how a single crystal splits.

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 sellers try to wrap every little flaw in a cloak of “mystical energy.” They’ll show you a stone with two distinct hues and tell you it’s a sign of … Read more

Diamond Fluorescence Can Affect the Appearance of Your Gemstone

October 4, 2025 by Dagny Solheim
Understanding diamond fluorescence and whether it matters.

I remember sitting in a cramped grading lab in Bergen, the kind of room where the air feels heavy with the smell of ozone and stale coffee, staring through a loupe until my eyes burned.

September 19, 2025 by Dagny Solheim
What a gemstone certificate actually tells you.

How to Choose the Perfect Princess Cut Diamond

September 13, 2025 by Dagny Solheim

I’ve seen enough “miracle stones” to know that the marketing departments are usually trying to sell you a dream that doesn’t exist in the mineralogy.

Brown Gemstones Can Be Far More Valuable Than They Appear

September 12, 2025 by Dagny Solheim
Brown gemstones and the ones worth more than they look.
