Its unpolished state offers a direct connection to ancient geological history, making it a unique piece for mineral collectors and history enthusiasts alike.

What affects the value of Raw Jasper Stone?

• The vibrancy and distinctness of the natural yellow and green color transitions.
• The overall size and weight of the specimen, with larger unpolished chunks commanding higher prices.
• The presence of unique geological patterns or inclusions that enhance its visual appeal.
• The physical integrity of the stone, specifically the lack of modern cracks or artificial polishing.

How to Identify Raw Jasper Stone?

• Look for the characteristic opaque clarity and waxy luster typical of high-silica microcrystalline quartz.
• Examine the surface for a conchoidal fracture pattern, which is a hallmark of authentic raw jasper.
• Verify the specific yellow and green color banding which should appear integrated into the stone rather than topical.
• Check for a high hardness level, as genuine jasper will typically scratch glass and cannot be easily marred by steel.
