This is a compact uraninite-bearing quartz specimen with a gritty, crystalline texture and warm iron oxide coloration. The surface is covered in small, sparkling quartz grains, giving it a rough, almost “sugary” look, while darker embedded zones reveal the underlying uranium ore. It’s a quieter piece visually—but one that rewards a closer look.
At ~25,000 CPM, this specimen sits right in the sweet spot for collectors who want reliable activity in a small, affordable form factor. It’s an excellent entry-level uranium ore piece, ideal for building a collection, learning mineral identification, or adding a compact comparison sample without sacrificing performance.
• Weight: 0.6 oz (17 g)
• Dimensions: approx. 1.45 × 0.8 × 0.7 in (3.7 × 2.0 × 1.8 cm)
• Locality: Likely Colorado Plateau / Western US uranium region
• Condition: Natural, unprocessed, no stabilization or enhancement
• Measured Activity: ~25,000 CPM
• Instrument: Ludlum Model 3 with 44-9 pancake probe
• Dose Rate: ~1.0 mR/hr (Ludlum Model 9 ion chamber)
• UV Response: None
• Shipping: Ships legally under UN 2910 – Excepted Radioactive Material
⚠️ Radiation Notice:
This specimen emits measurable ionizing radiation. Avoid prolonged handling and display appropriately.
• Location Blurb: Quartz-hosted uranium material like this is common across the Colorado Plateau, where uranium mineralization occurs along fractures and porous zones.
• Non-uranium minerals: Quartz/silica, iron oxides
• Activity Level: Moderate for size
• Best Use Cases: Beginner specimen, detector testing, comparison piece, educational display
• Who This Is Best For: New collectors or anyone wanting a compact, budget-friendly uranium sample
