EMERALD ROCK STONE

(Schist with Emeralds)

ANFA possesses one of the world’s biggest Emerald ​Rock Stone.


The stone, weighing approximately 617 lbs (280 kg)

(± 1,400,000 carats) originated from Bahia, Brazil ​and has emerald crystals embedded in the host ​rock.


Local people from the extraction area of this object ​has given a name to this rock stone as “Boi Verde”, ​meaning Green Ox.

History

The mine where the emerald was extracted is located in the city of Pindobaçu. This stone is a variation ​of beryl (Be3Al2Si6O18) and is the noblest amongst the types of this mineral. Other variations of beryl ​are aquamarine, bixbite, goshenite, heliodor, and morganite. The emerald's green color is due to the ​presence of minimal amounts of chromium and, sometimes, vanadium. It is prized as a gem, and the ​price per carat places it amongst the most valuable stones in the world, losing some of this value due to ​inclusions that often occur in all emeralds.


According to historical records, the Egyptians believed that the stone had the power to protect against ​the spirit's evils, besides being able to guide the future. Solomon was gifted an emerald by the queen of ​Sheba as a token of admiration. The Jews had it on the necklaces of the twelve tribes of Israel.


Emeralds adorned many artifacts, such as the "Holy Grail" (a name given to the cup used by Jesus on ​the Last Supper), papal tiaras, kings' crowns, and maharajas' turbans. They were used to garnish the ​princesses' laces and nobles' fingers. The Romans believed that it conjured up sorrow and turned pain ​into joy. The sailors carried it around their necks as amulets, hoping for a good trip in calm seas.


The emerald was considered to be a symbol of medicine. This was due to the fact that Asclepius, the ​mythological Greek physician, was adept at treating patients with plants.


During the Age of Discovery, the Spanish navigators, who were astonished by the number of emeralds ​the Inca civilization possessed, confiscated the stones. In Brazil, the search for these gems was led by ​Fernão Dias Paes Leme, a Bandeirante from São Paulo, also known as the Emerald Hunter. Solely for ​the purpose of finding emeralds, Fernão commanded a great expedition from the city of São Vicente, ​advancing through great extensions of woods. He ran into the Sertão of Minas Gerais and condemned ​his son to the gallows, and, as an act of vengeance, his son plotted against him.


The significant deposits of emeralds are in Colombia and also be found in large quantities in Brazil in ​the Serra da Carnaíba (Bahia), Campos Verdes (Goiás), Afghanistan, Pakistan, Russia, Zambia and ​Zimbabwe.

The issued Certificate of Identification & Authenticity states as ​follows;

The schist rock stone object has the following dimensions:

length 101.00 cm x average width 42.00 cm x average height 89.00 cm. The rock is composed of a dark-​colored matrix with embedded green emerald crystals.

The rock stone has a large number of green crystals in a hexagonal shape. The schist is classified as ​phlogopite schist, a dark-colored rock, generally purple due to chromium and marked with foliation. ​This schist is composed of 70% to 90% phlogopite, displaying millimeter to submillimeter crystals that, ​sometimes, make the phlogopite turn into chlorite.


It is possible to notice the second foliation in some schist sample areas, which cuts the first where ​hexagonal green crystals occur. In the schist sample, talc, quartz, chlorite, phlogopite, and beryl can be ​found in differing quantities.
