A striking necklace of swirly black, taupe, cocoa, grey and white Occo (Oco or Ocho ) agate geode. This piece is so unique and beautiful, with a gold plated edge and raw druzy crystal centre.
Looks great on its own or is fantastic layered, the mixed style chain adds a nice asymmetrical detail.
• Agate pendant: about 2 in (5 cm) x 3/4 in (2 cm) plus the loop and bail
• Chain: long composite chain of contrasting simple chain interspersed with fancy brass chain approx 36 in (91 cm) around closed jump ring- no clasp
• I have attempted to capture the color of this piece as best as possible. Please note that monitors and screens all display color and brightness a bit differently.
>>> A bit about Occos:
These beautiful little geodes are formed as gas bubbles in volcanic rock and sedimentary limestone.
Geodes are perfect little environments that contain minerals deposited from a slow seep of groundwater or hydrothermal solutions. Over time, layers of chalcedony (cryptocrystalline quartz) form, becoming lined internally by various minerals, often lovely sparkling crystals of quartz or with others including calcite, opal, chalcedony, or dolomite.
Each one has such a unique shape, color banding and crystal formation.
“Oco” (Occo, Ocho) is the word used in the area of Três Pinheiros, Fountoura Xavier, Rio Grande do Sulan, Brazil where this variety is gathered. An area where the rock formations are around 50 million years old!
Ocos are a second "crop" for farmers, they gather the geodes after the crops have been harvested and the fields have been tilled under- a process that both prepares the soil for the next planting and allows the Oco’s to appear
