Alexandrite is called the king of gemstones, but it is a mysterious gemstone that changes from blue-green under sunlight to brown to reddish-purple under indoor light.

Items that change color so much that they are called emeralds during the day and rubies at night are auction treasures.



The production areas are Russia, Brazil, Sri Lanka, India, Africa, etc.
It was originally discovered in Russia, but now it is rarely mined, making it rare and expensive.



Next, high-quality alexandrite was mined in Brazil, and a company called Emerald Mine acquired many alexandrite mines.
When it comes to diamonds, De Beers is famous for controlling the mines and controlling prices, but for alexandrite, Emerald Mine controlled both prices and quality.
However, because the miners were very poor, many of them hid the raw stones they extracted and sold them.
Many of the rough stones were not very good alexandrites, the cuts had few facets, and the tables were often too wide, so it was obvious at a glance that the quality was different.
However, since they were sold off-the-shelf, they were sold at a much lower price, and were called thieves' stones.
It is said that bad coins drive out good coins, but as thieves' stones became more common, the value of alexandrite decreased, and for a time, good ones were no longer in circulation.
However, as the output of mines has drastically decreased and high-quality alexandrite has decreased, its rarity value has increased, and the price of Brazilian alexandrite has soared in recent years.

If you have a good Brazilian alexandrite now, please cherish it.
It's getting more and more expensive.
