What Cherry Creek Jasper Looks Like
Cherry Creek jasper (also called Red Creek or Picasso-style jasper, mined in China) is an opaque microcrystalline quartz (chalcedony/jasper) known for soft pastel scenic patterns in creamy tan, pink, mustard-yellow, brick-red, grey-green, and slate-blue, often with darker dendritic or banded "landscape" markings. It has a dull to waxy luster when rough and takes a smooth, glassy polish. The texture is very fine-grained and dense, with no visible individual crystals.
Step-by-Step Field ID Checklist
- Color and pattern: Look for muted, earthy multicolor banding and landscape-like scenes.
- Texture: Confirm a fine, dense, opaque body with no visible grains.
- Luster: Waxy to dull when rough; high glassy polish when finished.
- Hardness test: It scratches glass and steel easily (Mohs ~7).
- Fracture: Look for smooth, curved conchoidal breaks with sharp edges.
- Acid test: No fizz (it is silica, not carbonate).
Key Diagnostic Tests
- Hardness: Mohs ~7; will not be scratched by a steel knife.
- Fracture: Conchoidal, sharp-edged.
- Acid reaction: None.
- Density: ~2.6 g/cm³.
- Streak: White.
Common Look-Alikes and How to Tell Them Apart
- Picasso jasper / marble: True Picasso "marble" is calcite-based and fizzes in acid and is softer (Mohs 3); Cherry Creek jasper is hard quartz with no fizz.
- Picture jasper (Biggs, Owyhee): Similar scenic look but typically browner; Cherry Creek tends toward brighter pastel reds, yellows, and greens.
- Mookaite: More uniform red-yellow-cream Australian jasper; Cherry Creek shows more varied slate and green tones.
- Dyed howlite or magnesite: Softer and fizz-positive or scratch-soft; Cherry Creek is hard and inert.
- Polychrome jasper: Madagascar material with more flowing color; Cherry Creek often has sharper banding and landscape lines.
Where Cherry Creek Jasper Is Typically Found
Cherry Creek jasper is mined chiefly in China (often marketed as Red Creek or Cherry Creek jasper) and reaches the lapidary market as rough and tumbled stones. It forms in silica-rich sedimentary or volcanic environments where iron and other oxides produced its varied banding. Most material is sourced commercially rather than collected in the wild by Western rockhounds.
Frequently asked questions
How can you tell if it is real Cherry Creek jasper?
Genuine Cherry Creek jasper is hard quartz (Mohs 7) that scratches glass, does not fizz in acid, and shows natural soft pastel landscape banding; soft or acid-reactive material is not true jasper.
What does Cherry Creek jasper look like?
It is an opaque jasper with muted scenic patterns in tan, pink, mustard, red, grey-green, and slate-blue, often with dendritic or banded landscape markings, taking a high polish.
Is Cherry Creek jasper the same as Red Creek jasper?
Yes, Cherry Creek and Red Creek jasper are common trade names for the same Chinese landscape jasper, also sometimes sold as Picasso jasper.
Is Cherry Creek jasper dyed?
Most Cherry Creek jasper is naturally colored by iron and mineral oxides, though some lower-grade stones on the market are dyed, so check for color pooled in cracks and verify quartz hardness.
