They come from the birthplace of the four famous names in the most authentic gemstones here (below)
For many people who know a little about colored gems, even if they don't know how to choose from the clarity color, they will ask where the gems are made. It sounds like a door. But the place of origin is not superstitious. It is not a standard that affects the quality of gemstones. It is that the quality of gemstones from a certain place is relatively high, but not absolute. However, places like Brazil, Sri Lanka, Myanmar, etc., do indeed know that these places have been produced regardless of whether they love colored stones.
Flashing eye of the king of tourmaline
As the king of the tourmaline, Paraiba is a very special blue tourmaline, which presents a very bright electro-optic blue color and can present a colorful fire. It is still extremely difficult to find and mine Paraiba tourmaline, and the known veins are often as thin as a pencil. Today there are only three mines in the world producing ParaÃba, one of which was that ParaÃba was discovered in 1982 and named after the land, ParaÃba, Brazil.
The other two are located in the northeast of Rio Grande do Sul and in the mining area south of Parelhas. ParaÃba's current production has already faced a severe situation. The global output of dozens of carats per month has to face fragmentation. The founder's rough stone is almost incomplete. The small pieces of the original stone are often only a few grams. That's why even the real Paraiba tourmaline on the market is usually only 0.1 to 0.5 carats, but it can still sell for a high price.

Little gossip: It is because of the rarity and value of Paraiba that the green tourmaline, which is generally slightly biased towards blue, is usually sold by the merchant as ParaÃba.

Many people know that emerald is the king of green gems, and is ranked among the world's top five gems, but the emerald is also believed to be "Columbia Emerald." When it comes to Colombia's production, this emerald seems to suddenly rise, and the high price makes people feel no complaints. What sets them apart is the darker green that is exposed to the impression of chrome vanadium.
The data shows that 80% of the world's top emeralds were produced in Colombia, and Colombia still has a 35% share of the world's top emeralds. In addition, Bogota, the capital of Colombia, is a world-famous emerald processing center where many high-quality emeralds are cut and processed.
