Description: 272 carat wood replacement opal.
Weight: 272 carat.
Origin: Banten, Indonesia.
Treatment: pieces have been rubbed in baby oil and may have been heated as that is a common practice in Indonesia to bring out the color.
Shape: Roots & branches.
Pattern: Black potch with sections of colorful opal. This is specimen grade.
Dominant Colors: Red, orange, green, blue.
Size: The biggest piece is 33mm x 29mm x 21mm.
Condition: Original.
Comments: These are specimens of wood replacement opal. Indonesian opalized wood is petrified wood in which the wood grains have been replaced by opal. Indonesia is a volcanic island chain that is currently active and this volcanic activity produces a wide array of unusual minerals and rocks. When wood is buried by volcanic ash and silica is mobilized from the ash, the silica will penetrate into the wood and replace the grains of the wood. Opal is a hydrated silica. The silica is often accompanied by other elements that give the opalized wood a wide range of colors. Red, green and purple colors are usually from iron minerals. Manganese often creates pink, black and brown coloration and copper minerals can produce blue and green.

Warum überbieten sich Nutzer selbst?
Wenn ein Gebot abgegeben wird, ist dies der Höchstbetrag, den eine Person für das Produkt bieten möchte. Unser System bietet dann automatisch im Namen des Bieters und erhöht das Gebot schrittweise bis zum Höchstbetrag, um die Position des Höchstbietenden beizubehalten.
Wenn ein Symbol mit der Aufschrift „Automatisches Gebot“ angezeigt wird, bedeutet dies, dass unser System aktiv Gebote für den Bieter basierend auf seinem Höchstgebot abgibt. Dies kann so aussehen, als würden die Bieter sich selbst überbieten, aber es ist lediglich das Ergebnis der Aktualisierung des Gebots durch das System, um das Höchstlimit des Bieters widerzuspiegeln.
