< p > strong > 1, how many colors are sapphire? < /strong > /p >

< p > although sapphire is attributive to blue word, it is not only a blue color.

In fact, sapphire is the general name of corundum other than rubies.

So besides blue, there are sapphires in pink, pink, yellow, green and white.

Among these colors, blue is the most popular.

But pink and Orange Sapphire are also very rare and of high value.

< p > < strong > two, where is the sapphire with good quality? < /strong > < /p >

< p > sapphire is mainly produced in Kashmir, Sri Lanka, Thailand, Burma, Australia and China's Shandong Changle.

Among them, the sapphire of Sri Lanka and Kashmir is generally indigo with violet violet color, which is bright, pure, pparent and of high quality, and is worth collecting.

Sapphires in Changle, Australia and Shandong are common in the market, but they are poor in pparency and impurities. Merchants will make them lighter by optimizing the method to enhance their value.

So the sapphire that we saw in Changle is generally optimized.

< p > < strong > three, and if the business is not enough, how can we identify it? < /strong > /p >

< p > this is indeed the case. The more common products are crystal, Topaz, zircon, fluorite and glass.

However, imitation can not imitate the hardness and density of sapphire.

In addition to diamonds, sapphire is the hardest mineral, the hardness of diamond is 10, the hardness of sapphire is 9, and the hardness of crystal is 7.

Therefore, sapphire can be used to cut glass, but imitation is not acceptable. It can be regarded as one of the identification methods.

Second, official certification is also a guarantee for sapphire quality.

< p > strong > four, what is the optimization of sapphire? Is the optimized sapphire value not high? < /strong > /p >

< p > this method is very common. It can be said that 90% of the sapphires on the market are optimized and very few natural ones.

It is through heating to change the color of gemstones, also known as heat treatment.

Because optimization is a very common practice, it will not change the structure and quality of sapphire. Therefore, according to international practice, the optimized sapphire can not be explained in sales, and can not be tagged on the identification certificate.

If we say "processing" alone, then the method will not only be heated, but also filled and stained. The beautified sapphire treated will be marked "Sapphire (processing)" on the identification certificate.

What are the criteria for selecting sapphire when < p > strong > five? < /strong > < /p >

< p > of course, choose sapphire according to 4C standard.

4C: color, cleanliness, cut and weight.

First look at the color and the fire color.

The more vivid the color, the more pure and even, the higher the saturation, the more valuable the gem.

Next, look at cleanliness, that is, to see if there are impurities, flaws and cracks.

Then we'll see the cut.

If it is faceted Sapphire, it depends on the symmetry of the facets and the cutting ratio of the whole gemstones.

Finally, when the first few conditions are almost the same, the bigger the sapphire, the better.
