資産価値ある非加熱サファイア、価値のない非加熱サファイア

Unheated sapphires with valuable assets, unheated sapphires with no value

There are three important points to keep in mind in order not to make any losses with sapphire.

First of all, there are three categories of sapphire: unheated, heated, and treated.

These items have very different values, but please be careful as bad sellers sell them without clearly explaining this.

There are some things to keep in mind when it comes to sapphires, which can be a big loss if you don't know about them .
Many people misunderstand that just because something is not heated doesn't necessarily mean it is of good quality, rare, or valuable.
Unheated sapphire is a completely natural sapphire made by polishing and cutting raw sapphire without heating it.
The value and price of unheated sapphire can vary from several times to hundreds of times depending on the quality.
The most valuable unheated sapphires are those with high transparency and few inclusions, but the value and price vary greatly depending on the color.
Good quality has high asset value and rarity value, and the price will continue to rise in the future.

Sapphire of the highest quality has high transparency and beautiful color even without heating, and if it is produced in Kashmir, it can be said to be a truly valuable sapphire.
Kashmir sapphire is no longer produced and is called a phantom sapphire, but it is rarely available other than when past Kashmir sapphires come up for auction. It is a treasure that will increase in value.
For Kashmir sapphire, you can trust GUBELIN or SSEF identification. Anything else will be devalued and have no value.
This is very important when purchasing.
Kashmir sapphires that have value must be marked with GUBELIN or SSEF.
Some Kashmiri sapphires are worth tens or even hundreds of millions of dollars at auction, so their prices will continue to rise in the future.
Rare, high-quality gemstones that are no longer produced can be compared to the works of a great painter after his death.
Royal blue unheated sapphire is also very valuable.
Highly transparent and large items are becoming more and more expensive.
Even if you don't go that far, it's worth purchasing an unheated sapphire with good color and few inclusions that is over 3 carat.

However, there is an unheated sapphire that you should absolutely not buy ! !
This is a common trick used by bad companies, and sadly many amateur customers are fooled.
Unheated sapphire refers to sapphire that has not been heated, but sapphires that cannot be heated because they have too many inclusions or cracks inside, or are of poor quality, will break if heated. There are sellers who sell it saying that it is valuable because it is unheated sapphire or because it is large.
Even if it is 10ct to 50ct, it has no value.
There is a risk that this will break or break during use.

Unheated sapphire is a gemstone that should be purchased from a proven and trusted supplier.



Next, heated sapphire is a sapphire that is cut and polished after heating the raw sapphire stone to hundreds to thousands of degrees for several months to increase its transparency and deepen its color.
Heating does not necessarily mean a significant drop in value; sapphire with high transparency and beautiful color is valuable.
In Sri Lanka and Thailand, there are many workshops that heat the process, and at each workshop, secrets such as the temperature, heating period, and catalyst used are passed down from generation to generation.
Vendors from Sri Lanka and Thailand come to us to buy unheated sapphires, take them home, heat them in our workshop, turn them into beautiful sapphires, and some are professional traders who resell them at a high price.
We don't know what color it will be after six months, and sometimes it's a gamble, so to diversify the risk, several people buy it together, and after six months, we take it out from the heat and sell it.
Of course, you may lose money, but if things go well, you can get more than 10 times the original price, so there are several Sri Lankans who come to buy it every month.

Finally, treatment is a method in which something like lead glass is added to the rough stone and heated for several weeks to several months. Even with very poor quality rough stones, even if you heat them as is, they will not turn out to be beautiful sapphires. It is performed on rough stones with poor color and transparency that are judged to be unusable.
When it is identified by an appraisal agency, it will be treated as a treatment.
This uses a completely different technology from normal heating, so it is far cheaper than heating.
There is no problem if you use it as an accessory, but it has no real value as an asset.
Please be aware that there are products that are sold at high prices by bad companies, TV shopping, and mail order without being labeled as treatments.
