Septerye is a combination of Calcite, Chalcedony and Aragonite. Septerye is formed when cracks appears in solidified Silica found in seafloor sediment mineral accretions and fossil stones. When the nodule (mud based rock) cracks, due to shrinkage, colonies of micro sea organisms settle into the cracks. When these organisms and minerals crystallize, they create a layer of calcite which acts like a cementing type of bond between the cracks of the sedimentary mud rock, Chalcedony and Aragonite. This rock type has lovely colours and fantastic patterns. Classically polished into an egg format and appropriately named Dragons eggs which tend to have crystalline exposures. Balls, hearts and other polished lines tend to have frequent crystalline areas. Price is grade dependent. Items are as shown.
