How to choose a beautiful diamond? Diamonds are different from gold and platinum. In general, precious metals such as gold have a uniform price, but diamonds are different, and its price is subject to various factors. For example: carat number, clarity, color, cut. So how can we pick out a beautiful diamond?

In general, the greater the number of carats, the higher the value. In the early 1990s, in the US market, a carat of high-quality perfect diamonds cost about $15,000, and a five-carat perfect diamond worth more than $200,000, averaging about $45,000 per carat. From the perspective of diamond investment, it is generally better to buy diamonds of more than 3 carats. In addition to the carat number, consider whether the clarity, color and quality of the diamond are in line with the price.

Clarity: refers to the amount of diamond inclusions. According to the American gia standard, diamonds with a flawless interior and surface are called innocent. The inclusions are some fine carbon materials hidden in the uncrystallized diamonds. The less the diamond content, the more precious the value.

Color: If non-colored diamonds, the color of the diamond is as white as possible, and the top is excellent white (d colour 100 colors) (e colour 98 colors), etc., roughly, for the quality of diamonds It is a diamond of 95 colors or more.

Cut: A fine cut diamond, a diamond that can receive light from the crown, reflected to each flap, and finally refracted from the crown. The more light that is reflected, the more the diamond's flaw can be expressed, so it is excellent. Cutting is one of the indispensable conditions for choosing a diamond.
