With its vivid textures and shimmering inclusions, this material is highly attractive for collectors and lapidary enthusiasts alike.

Well-suited for cutting, polishing, and lapidary work – yet also a beautiful raw specimen for anyone interested in fossil-bearing gem materials.

Geology & Origin
The Garut area in West Java is renowned for its geologically diverse deposits, producing not only fossil woods but also various types of opal. The fossilized wood originated in Tertiary volcanic layers, where organic material was gradually replaced by silica. Later hydrothermal processes introduced opal, forming yellow to greenish veins within the fossil matrix.

Garut material is internationally appreciated for its stability, excellent polishability, and unusual color combinations. The striking interplay between fossil textures and gem-like opal makes this stone a sought-after raw material in both the mineral and lapidary markets.
