This newly found and extremely rare purple moss agate from East Java is very beautiful. The contrast between the green “moss” and the purple chalcedony, coupled with unique patterns makes this a particularly special gemstone.

This rare, natural & untreated agate from Indonesia is the first ever scene, moss or plume agate to have this deep purple color. This new to the market, never seen before purple moss agate will really impress customers if made into jewellery, or even when sold as a stand-alone gem or specimen.

The purple color is caused by the presence of rare manganese at the time of formation. The green moss banding is due to the presence of clay minerals at the time of formation of the chalcedony/agate. Together these features have formed an extremely beautiful display of natures beauty.

The East Java Plume Agate is hosted in orange-red jasper which has been splintered by faulting and flooded with blue-ish white chalcedonic quartz veins. The underwater scene, flame and plume shapes occur along the fringes of the veins and occasionally as wedges and pods within the veins. In the soil they find silicified nodules of greenish to golden yellow, orange and red plumes and flame shapes. The minerals forming the plumes are mainly yellow goethite and red hematite. They occur along with white crusts of hydrated silica and black to brown pockets and outlines of iron or manganese hydroxide minerals
