The beautiful green emeralds we love to wear today were formed 30 to 50 million years ago, but have only been mined the past several hundred years. Colombia is the most famous source for emeralds and their chief attraction is their outstanding color. According to The Culture Trip, 70-90% of the world’s quality emerald market stems from Colombian emeralds, which is shown in the country’s significant increase in foreign direct investment over the past few decades. Colombia has an interesting and prosperous sector which is proving to be more competitive than ever before.


Zambia started their large scale emerald mining around 1976 and their gemstone trade have attracted major attention since then. The Republic of Zambia are rich in gemstones with notable material that shows its beautiful transparency, clarity, and brilliance. We respect and recognize the precious emeralds for its distinctive characteristics and their dark-green or bluish tone, especially under radiant light. Many of the emerald mines in Zambia has a long history of producing high quality emeralds which leads them to constitute about 20% of the world’s supply.


Brazil is not only known for its colorful festival and diversity of climates and cultures, but the spectrum of colorful gems is bringing the country just as much attention. Mining has taken place in Brazil since the 1700s and some extremely large gemstones have been unearthed there. Almost 300 years later, some of the finest blue-green tourmaline crystals ever seen were discovered, and its bright and unique color was caused by the presence of copper and manganese. The bright turquoise color makes the Brazilian tourmaline extremely popular and its scarcity has made it very valuable.
