Emeralds that are still worth more and emeralds that will not go up in value.

Natural emeralds continue to rise in value.
Among them, there are emeralds that are still valuable and emeralds that will not go up in value.

Emeralds come from many countries and regions, but the most valuable and beautiful are from Colombia.
The transparency of emeralds is clearer, more brilliant, and the color is a beautiful green.

If you want to buy emeralds, Colombian emeralds are the best to buy.
Emeralds vary greatly in value and price based on color and oil.
The most valuable color is VIVID GREEN, but the muzo color is the most valuable and is increasing in value worldwide.

Most emeralds are cut and polished with oil, but non-oil emeralds, which contain no oil at all, are very rare and highly valuable.
However, non-oil is so delicate that if you touch it with your hand and get oil on it, it is no longer non-oil, and if you want to use it as jewelry, you do not need to be so particular about it.
 Next to non-oil, there is INSIGNIFICANT, which has a very small amount of oil, which is also rare and valuable.
Next is minor oil, which means that a small amount of oil was used in the polishing cut, which is also a valuable level.
However, the level of oil and color are not given by the Japanese domestic assay, and an overseas certificate must be obtained.
For everyday use, emerald jewelry does not require such a level of certification.
Even if they are small, Colombian emeralds of good quality with good color and brightness and good transparency should be bought now because the price will go up.
Emeralds that are dark in color, but packed and lack brightness are of poor quality and should not be bought even if recommended.
Also, even if they are large, it is best not to buy emeralds that are light in color and have many scratches, as you will get tired of them later on.

Next is a Zambian emerald.
The Zambian variety is darker in color, but many of them have black inclusions, giving them a darker appearance.
Even if the vendor tells you that they are good because of their dark color, they are not as valuable or beautiful as Colombian gemstones.

Emeralds from Brazil are also distributed, but these have no black inclusions and high transparency, but the color is more yellowish green than green, and the color is less attractive.

About 30 years ago, I used to buy a large quantity of Colombian emeralds of 3ct to 30ct from a person who is called the god of emeralds, but at some point he told me that there were not many this time because the number of emeralds he could get had suddenly decreased.
When I forced them to tell me why, they told me that for some surprising reason, the amount of mining had drastically decreased.
At that time in Colombia, a lot of good emeralds were mined near rivers in the mountains, but when you dig near a river, water comes out and you have to pump up the water to continue digging.
And pumping up the water naturally uses electricity.
This power was very expensive, so the contractors stole electricity from nearby power lines and power plants, and used that power to dig.
However, the electricity thieves were discovered, and they were forced to produce their own electricity, which cost so much that mining became impossible.
My supplier had been buying from a supplier called "the thief's stone," and he told me that he could no longer get such cheap and good emeralds.

I have a friend who is an emerald dealer called Mr. H.
This Mr. H. would buy cheap emeralds with many inclusions and sell them at a high price by using a machine he made himself to infiltrate the emeralds with hot oil heated at high pressure to increase their transparency and make scratches and inclusions less visible.
One day, Mr. H. showed up, wrapped in bandages, and said that while he was pouring the oil, the machine exploded and the hot oil splashed all over him, burning him badly.
He told me that he had to experiment every day just to fill the machine with oil, and that it was very difficult.
If that is the case, I wonder how hard it is for the people who are mining, abrasive cutting, and filling the oil on site.

When I think about the history of each emerald, I love each gemstone, no matter what quality it is.
