Description: Pink Opalized Petrified wood, 225 gram Natural Rough Slab .origin - West Java Indonesia. Materials: petrified, wood, opalizedPink Opalized Petrified wood, 225 gram Natural Rough cut Slab origin - West Java Indonesia.weight : 225 gramsBeautiful slabs to cut and cab into mashed pair cabs, one of kind cabochons of all shapes and specs. Stunning raw material to work with to make those eye catching unique jewelry pieces. Or just as nice to use for home decor, side tables and rare earths beauties collectors.These beautiful slabs were directly purchased out of Indonesia personally from a gem trader whose specializes in materials of Indonesia such as confetti chrysocolla, native copper, palmea gem silica, materials from West Java , Northern Indonesia , grape agates, a new discovery which we will be listing soon of a chrysocolla Chalcedony , plume chrysocolla chalcedony and pink opalized petrified wood.The value of petrified wood depends on weight, color, quality, and whether it is polished or not. Worked out wood (statues) are more expensive. In the factory that we visited (Petrified Wood Indonesia, 90 min from Jakarta) the prices were between Rp 15 000 – 50 000 per kg (don’t forget that pieces are rather heavy).In Kemang store (Jakarta) you pay for the convenience, so the prices are 3x more expensive than in the factory, but still very reasonable (coaster Rp 75 000, candle holder Rp 200 000, bowl Rp 1.8 mio, bookend small size Rp 200 000, bookend medium size Rp 300 000) Most of the petrified wood is millions of years old.The Gilboa fossil forest (USA) is 385 million years old and is generally referred to as 'the oldest fossil forest'. The youngest petrified wood was created by scientists in ideal conditions in tenths of years.Indonesia's largest deposits of petrified wood come mainly from drastic volcanic activity and flooding around 20 million years ago.Indonesia’s petrified wood is coming mainly from West Java from areas like Banten and Mount Halimun Salak National Park.Red and pink Opalized Petrified wood | cut slab- Beauty from West JavaKey features of opalized petrified wood:1. It is a translucent to opaque stone.2. It can have a variety of colors, including white, yellow, orange, red, blue, green, and black.3. It often has a play of colors, known as opalescence.4. It can be cut into cabochons, beads, and other shapes.The country of Indonesia is situated in SE Asia. The capital, Jakarta, in West Java, lies on the western end of the island of Java nestled amongst composite volcanoes. Indonesia consists of 17,508 islands which extend over 5,120 kilometers from east to west. The country lies in a highly active tectonic belt. The tallest mountains reach 4,884 meters and nearby ocean trenches reach depths of 4,440 meters.Some of these islands have experienced millions of years of intermittent volcanic activity as a result of the spreading Indian Ocean floor sinking beneath the islands and melting as it becomes heated at depth. In fact there are 129 active volcanoes in Indonesia today, accounting for 13% of the active volcanoes in the world. With each volcanic eruption, millions of tons of volcanic ash are blown into the sky. This material rains down upon the land, burying the forests, filling lakes and choking rivers. Some large eruptions can deposit layers of volcanic ash locally up to hundreds of meters thick. Ash deposits can cover hundreds if not thousands of square kilometers.Some of these islands have experienced millions of years of intermittent volcanic activity as a result of the spreading Indian Ocean floor sinking beneath the islands and melting as it becomes heated at depth.

Around the World, petrified woods can be found in both volcanic and sedimentary rock formations. Typically the woods are preserved by burial in volcanic debris but after it becomes petrified, it can be eroded from the volcanic strata and re-deposited in sedimentary formations, such as sandstone, siltstone or shale. The volcanic rock formations in which preservation of woods occur, are usually high silica (SiO2) content volcanic tuffs and breccias from violent explosive eruptions. The classification of these rocks range from dacite to rhyolite. Some silica rich tuffs mature into colorful jaspers. The preservation of these ancient forests occurs thru processes of infill and replacement of the organic components of the woods with minerals deposited by hot waters trapped within the rock formations. The pores of the woods are filled and the fibers are replaced cell by cell with a variety of minerals dominantly composed of silica (SiO2) and carbonate (CaO3). Various colorations imparted to the woods during preservation are from iron, manganese, copper and other dissolved metals.The ancient processes which preserved woods and formed fossils are no different than the processes acting on modern forests when a volcanic erupts today. The difference we see is only that which results over time. Initially the silica (Si02) is dissolved from the decaying volcanic ash during exposure to oxygenated surface waters that descend and mix with the loose deposits of volcanic ash. The groundwater becomes acidic and dissolves silica and other minerals released from the ash. This dissolved silica in the form of silicic acid, attaches itself to the lignin and cellulose of the wood. Colors of rich orange, red and purples resulted from the iron, manganese and other elements in the mix.Over time, silicic acid dehydrates into silica gel. Through a process called permineralization, the silica gel and other minerals eventually fill the pores and encase the wood.Ships from NJ USA Ships same or next day USPS first class mail safe and secure Ships domestic USA only
