4 Ways to Tell if yellow Jasper is Real

"yellow Jasper" is a widely popular name frequently used by merchants to classify various yellow materials, such as yellow Aventurine, yellow Calcite, yellow Serpentine, and yellow Dyed Quartzite, even if they may have no relation to real Jasper. It's advisable to make purchases from reputable retailers and, if possible, request a certificate from a gem testing laboratory. Here are some handy tips to help you initially discern the authenticity of yellow Jasper.

1. Check Transparency with a Flashlight

Real: Real Yellow Jasper is opaque and does not allow light to pass through when illuminated with a flashlight.
Fake: Some fake Yellow Jaspers may appear translucent, allowing slight light transmission when illuminated with a flashlight. This is a key indicator that it is not a genuine Yellow Jasper.

2. Check the Grainsize

Real: Real Yellow Jasper is composed of microcrystalline quartz particles invisible to the naked eye, resulting in a fine texture without apparent mineral grains.
Fake: If visible mineral grains are present and the texture is coarse, it may not be real Yellow Jasper, but rather potentially an imitation like yellow aventurine, dyed quartzite, or other materials.

3. Hardness Test

Real: Real Yellow Jasper cannot be scratched by a knife. After a period of use, real Yellow Jasper typically doesn't exhibit noticeable wear.
Fake: Some imitations, such as calcite and serpentine, have a lower hardness than real Yellow Jasper and can be scratched by a knife. Over time, these low-hardness imitations will exhibit noticeable wear and gradually lose their original luster.

4. Acid Test

Real: No visible reaction will happen when hydrochloric acid or white vinegar is dropped on real Yellow Jasper.
Fake: Fakes made from carbonate materials like calcite may exhibit fizzing or effervescence when exposed to hydrochloric acid or white vinegar.
