Geological Intelligence
At Geode Glimmer, we believe that understanding the crystalline structure of the earth shouldn't be reserved for academics. We've built an open-access lab for enthusiasts to master mineralogy from the ground up.
Crystal Habits
From acicular needles to botryoidal clusters, identify how minerals grow in nature.
Cleavage Planes
Learn the geometric precision of how specimens fracture along atomic lines.
Hardness database
Quickly reference the Mohs scale for any silicate or carbonate in our collection.
Lustre & Streak
Identify non-metallic and metallic sheen through standardized optical guides.
Core Concepts
Master the fundamentals of modern geology and protect your collection from counterfeits.
Understanding the Mohs Hardness Scale
Why is apatite harder than calcite? We dive deep into why 1822 laboratory standards still matter for your private collection today.

Identifying Fake vs. Natural Minerals
Don't get tricked by heat-treated citrine or lab-grown hydro-quartz. Our team shows you how to spot the red flags instantly.
Expert Tips
The Geology of New York
From the double-terminated Herkimer Diamonds of Upstate to the mica-rich Manhattan Schist keeping our skyscrapers standing. What's underneath 1326 Herkimer Street?
Local MapCurator's insight
Ever wondered why some crystals feel surprisingly heavy for their size? Specific gravity is the secret metric most collectors ignore.
