💰 Oregon Rock & Mineral Value Guide
Estimated values for Oregon rocks and minerals (prices vary by quality, size, and rarity)
💡 Pricing Tips from Ryan
Quality matters most! A small, perfect specimen is often worth more than a large, flawed one.
Provenance: Rocks with known Oregon locations are more valuable than unknowns.
Rarity: Common rocks like basalt have low value, while rare sunstones can be priceless!

🌊 Deep Dive - Oregon Rock Geology
Dive deep into the fascinating geological stories of Oregon's rocks and minerals!
🌋 The Volcanic Legacy
Oregon sits on the Pacific "Ring of Fire," creating incredible geological diversity. The Cascade Range continues to build new volcanic rocks, while ancient lava flows created the massive Columbia River Basalt Group that covers much of eastern Oregon.
The Columbia River Basalt Group erupted 6-17 million years ago and covers over 50,000 square miles!
💎 Sunstone: Oregon's Crown Jewel
Oregon sunstone contains tiny copper platelets that create its famous sparkle called "schiller." These formed in basaltic lava flows millions of years ago. The Ponderosa Mine in Lake County produces some of the world's finest specimens, including rare red and green varieties.
Some Oregon sunstones show incredible "watermelon" coloring - green on one side, red on the other!
🔮 Thunder Eggs: Nature's Surprise Packages
Thunder eggs form in gas bubbles (vesicles) within rhyolite lava flows. Over millions of years, silica-rich water deposits colorful agate layers inside these cavities. Each thunder egg is a unique geological time capsule, and you never know what's inside until you cut it open!
The Priday Ranch near Madras produces some of the world's most beautiful thunder eggs!
🟫 Jasper: Earth's Ancient Paintbrush
Oregon's famous Picture Jasper formed in ancient lakebeds where silica replaced organic matter and sediments. Iron oxides create the beautiful landscape-like patterns that look like painted desert scenes. Biggs Jasper is particularly prized for its scenic beauty.
