Raw Agates from Indonesia (Sumatra) – River Pebbles – 1 kg
This listing is for a 1-kilogram package of raw river agates from Sumatra (Indonesia). These stones occur as natural river pebbles that have been tumbled and smoothed by river currents over millennia.

Due to the alluvial nature of the deposit, the material consists of smaller, very manageable nuggets—on average, there are 5 to 10 agates per kilogram, which provides a substantial amount to cut.

River Pebbles from Sumatra – A Geologist’s Box of Surprises
Agates found in the riverbeds of Sumatra are among the most exciting stones for DIY processing. River water acts as a natural grinding drum—over the centuries, it has worn down and selected the hardest, most silica-rich fragments, eliminating the surrounding soft rock. The outer, unassuming, and smooth surface of these river pebbles perfectly conceals what lies within. River agates from this region are famous for the incredible surprises they reveal when cut open. Inside, you can discover both classic, concentric agate bands and fanciful moss-like patterns, jasper inclusions, and crystalline geodes filled with fine quartz.
