Indonesia is rich in various types of stones, including natural stones, gemstones, and construction materials. The distribution of stones in Indonesia is influenced by its geological conditions, which include volcanic activity, tectonic movements, and mineral-rich regions. Here’s an overview of stone distribution in Indonesia:

1. Natural Stones (for Construction & Decoration)
Indonesia is a major exporter of natural stones such as:
– Andesite – Found in West Java (e.g., Majalengka), Central Java, and East Java.
– Basalt – Common in Lampung and West Java.
– Marble – Major deposits in Tulungagung (East Java), Sulawesi, and Nusa Tenggara.
– Granite – Found in Sumatra (Lampung), Kalimantan, and Riau.
– Sandstone – Common in Banten and Yogyakarta.
– Limestone – Abundant in Central Java (Gombong), East Java (Tuban), and Sumatra.
2. Gemstones & Precious Stones
Indonesia is known for its high-quality gemstones:
– Agate (Batu Akik) – Found in Aceh, Banten, and West Java.
– Jasper – Mainly from Pacitan (East Java) and Lampung.
– Chalcedony – Common in Kalimantan and Lampung.
– Petrified Wood (Fosil Kayu) – Found in Banten and Central Java.
– Diamonds & Sapphires – Small deposits in Kalimantan.
3. Volcanic Stones
Due to Indonesia’s active volcanoes:
– Pumice Stone – From volcanic regions like Mount Merapi (Central Ja.jpg)
.
– Lava Stone – Used for construction; found near volcanoes.
4. Mining & Quarrying Regions
Key stone-producing provinces:
– Java: Major for limestone, marble, and volcanic stones.
– Sumatra: Rich in granite, sandstone, and agate.
– Kalimantan: Known for gemstones like diamonds & quartz.
– Sulawesi: Produces high-quality marble.
– Nusa Tenggara: Limestone and marble sources.
5. Export & Industry
Indonesia exports natural stones to China, India, the US, Europe, and the Middle East. Key export products include:
– Granite slabs
– Marble tiles
