Emeralds are found all over the world but Colombia is by far the world’s largest producer, constituting 50–95% of the world production, with the number depending on the year, source and grade. Zambia is the world’s second biggest producer and Brazil third.

Historically, the most famous antique emerald mines were found in Egypt.

The ancient Egyptians appear to have obtained emeralds from Upper Egypt, where it is said to have been worked as early as 2000 BC. Greek miners were working the mines in the time of Alexander the Great, and later the mines yielded their gems to Cleopatra.

The Hindu scriptures known as the Vedas assert that emeralds promise good luck and enhance well-being.

Pliny the Elder (23–79 AD), the Roman scholar, was the first to suggest emerald was a family member of beryl. It was not until the early 19th century that science proved him right.

During the Spanish conquest of South America, vast quantities of emeralds were taken from several rich deposits in Colombia.

The Bahia Emerald is one of the largest emeralds and contains the largest single shard ever found. The stone, weighing approximately 341 kg (752 lb) (approximately 1,700,000 carats) originated from Bahia, Brazil and is emerald crystals embedded in host rock. It narrowly escaped flooding during Hurricane Katrina in 2005 during a period of storage in a warehouse in New Orleans.

Because of emerald’s high value, attempts were long made to manufacture it synthetically. These efforts finally met with success between 1934 and 1937, when a German patent was issued to cover its synthesis. Synthetic emeralds are currently manufactured in the United States by either a molten-flux process or a hydrothermal method; in the latter technique, aquamarine crystals are placed in a water solution at elevated temperature and pressure and used as a seed to produce emeralds. The crystals thus grown appear very similar to natural crystals and rival them in colour and beauty.
