Bumblebee "Jasper" is the trade name (technically not a real jasper) for this colorful, carbonate-rich rock that is only found in West Java, Indonesia. This vibrant rock is made of fibrous calcite with a distinctive yellow, orange, and black banding. The different colored bands are due to different mineral inclusions within the calcite's crystalline matrix. This material is relatively soft, with a Moh's hardness of 3. 

Our coarse material is considered to be pea- sized gravel, ranging between 4 millimeters to 2 millimeters. Please see the corresponding sediment size chart.
