Sapphire is a blue gem. This idea is not entirely correct, because sapphire is all corundum except ruby, yellow, green and so on. When choosing sapphire, we should pay attention to these aspects.
When you hear the name of sapphire, many people will not feel strange. The heart of the ocean in Titanic will appear in the mind, or the 18-carat ring of Princess Diana of the British royal family. These are sapphires. Wrong, but not all blue gems are sapphires, and sapphire is not limited to blue.

First, sapphire does not mean only blue gems
Many times the name of a jewel can be as its name suggests, but it is not appropriate to put it on sapphire. Sapphire is not just a blue jewel. Simply put, sapphire is a general term for other colors of corundum except ruby. So in addition to blue, there are pink, pink, yellow, green and white sapphires. Of course, among these colors, blue is the most popular, but pink and orange sapphires are also very rare and of high value.
Second, how to identify sapphire jewelry
The most important thing to buy jewelry is imitation, but one thing is clear. Sapphire is the hardest mineral except diamond. The hardness of diamond is 10, while the hardness of sapphire is 9. The hardness of crystal is 7. Therefore, sapphire can be used to draw glass, imitation can not, imitation can not imitate the hardness and density of sapphire, which can be regarded as one of the identification methods. Of course, the certification of the official agency is also a guarantee of sapphire quality.

Third, how to buy sapphire jewelry
Sapphire jewelry can also be selected according to the 4C standard, which is the color, clarity, cut, weight. The first thing to look at is the color. The more pure the color, the higher the saturation, the higher the value of the gem. Then there is the clarity, that is, whether there are impurities, flaws and cracks. Then look at the cut, if it is a faceted sapphire, it depends on whether the facet is symmetrical, and the proportion of the overall gemstone cut. Finally, the sapphire is as good as possible in the first few conditions.
