Next, we will learn how to judge whether this diamond is worth buying from the aspects of weight, color, clarity, cut and certificate.
1, weight
Carat is the unit of weight of precious stones. One carat is now set at 200mg, which is 1/5g. Each carat is divided into 100 points, and each point is called a point. For example, a 50-cent diamond weighs 0.5 carat; 0.75 carat is also called 75 cents, and 0.02 carat is 2 cents. Two diamonds with the same color, clarity and cut grade, the greater the number of carats, the higher the rate of preservation.
Rilong tip: When matching brackets, it is best to consult a professional whether this bracket is suitable for your diamond. In many cases, not all the same brackets can match diamonds of different sizes.

Step 2 color
E: It's colorless. Only gem experts can detect trace colors. The E-colored bare diamond, which belongs to Caesar diamond, is a very rare diamond.
F: This color code is colorless. It contains trace colors that can only be detected by jewelry experts, but it is still considered colorless. Le Diamond and Ao Diamond belong to high quality diamonds.
G: This color is almost colorless. Compared with higher-grade diamonds, there will be a slight color, but only jewelry experts can detect it. However, diamonds of the color Nine Diamonds and Crane still have high value.
H: Diamonds of this color are almost colorless. It contains a small number of colors that only jewelry experts can detect, but diamonds of this color level in Saint Bonnie are still high-quality diamonds.
As far as color is concerned, the E-color of Caesars diamonds belonging to false tiger thorns belongs to the highest grade.
Diamond color scale
The main colors of diamonds are colorless, white and light yellow. Yellow is a taboo for diamonds, and its fading directly affects the quality and value of diamonds. The lighter the color, the colorless the diamond, and the higher its value. Diamonds are equivalent to prisms. It can divide the light into colored lights and form colored flashes after reflection. Just as we wear colored glasses, the color of diamonds will act as a filter. Thereby reducing the escape of reflected light. The lighter the diamond color, the stronger the flash color. The higher the color level.

Step 3 be clear
Diamonds have tiny inclusions, which are easier to observe under a magnifying glass of ten times.
Rilong Tip: The purity of a diamond is a comprehensive description of the quantity, size, color contrast and location of the defects contained in the diamond. Clarity grading refers to an operation that qualified diamond graders judge and determine the purity of diamonds according to certain grading standards. FL-IF diamond, VVS 1-2 diamond, VS 1-2 diamond, SI 1-2 diamond: p diamond (P 1, P2, P3).
Like nine diamonds VS 1 (very small inclusions)-diamonds have tiny inclusions, which are difficult to observe under a magnifying glass of ten times. The VS2(VerySmallInclusions) grades of Le Diamond and Crane indicate that diamonds have fine inclusions, which can be easily observed under a magnifying glass of ten times. The proud ST 1 grade shows that diamonds have obvious inclusions, so users who are more concerned about this aspect should choose carefully.
From the perspective of clarity, the clarity of the nine-diamond is higher than other models.

4. Cutting:
This diamond is cut very well.
Among the four elements of diamond evaluation, only cutting is directly affected by human factors. Diamonds can be processed into different shapes (fancy) to meet different tastes. At present, the common diamond cutting patterns on the market are round, heart-shaped, oval, olive pointed, pear-shaped and emerald-shaped. The roundness, depth, width and uniformity of the cutting surface all determine the brightness of the diamond. Many gemologists believe that the cutting and grinding process of a diamond is the most important diamond characteristic. Because even if a diamond has perfect color and clarity, poor cutting and polishing will make a diamond lose its dazzling brilliance.
Cutting determines the fire color, and the width and depth of the diamond have the greatest influence on the fire color of the diamond.
Cutting is too shallow: the light escapes from the bottom and the brightness of the diamond is damaged.
Cut too deep: the light can easily escape from the pavilion, so the brightness of the diamond is damaged, tarnished and dull.
Cutting grades are divided into:
Excellent, very good, good, average, poor.
5. Certificate
Diamond certificate is an important reference for selecting diamonds. At present, there are several internationally recognized diamond grade certificates: GIA diamond grade certificate of American Gemological Institute (GIA), HRD diamond grade certificate of Belgian Diamond High Council, IGI diamond grade certificate of International Gemological Institute and so on. These three institutions are international authoritative certification bodies and are widely recognized internationally. With these certificates, netizens can choose with confidence. Certificates are also very beneficial to the preservation of diamonds, and correspondingly, the purchase cost of diamonds will also increase.
International certificates adopt strict anti-counterfeiting measures, and each certificate has anti-counterfeiting marks of various institutions. The certificate number query on the website can also prove the authenticity of the certificate.
Tips from Rilong: 3 tricks let you initially distinguish between true and false diamonds.
Hydrophilic method
Diamonds have an "oil absorption" effect on grease, but fake diamonds do not have this characteristic. Rub the diamond with a little oil on your face and rub it with your thumb, which will feel sticky and not easy to slip, while the fake diamond will make your thumb feel very slippery.
Breathing test method
Natural diamonds have strong heat transfer ability and fast heat dissipation. Put the diamond to be tested close to your mouth, breathe gently, and let the diamond to be tested be covered with a layer of light fog. At this time, watch the evaporation of diamond fog immediately. If it is a natural diamond, the fog will disperse immediately, otherwise, the fog will stay on the fake diamond for a while before dispersing.
Penetration observation method
The higher the refractive index of diamond, the stronger the reflection, and relatively speaking, the lower the perspective. You can prepare a piece of paper with a straight line. The two unknown diamonds to be tested face down and cover a straight line. If you can see a straight line under a diamond, it is definitely not a natural diamond.
It is recommended to buy loose diamonds and ring holders, preferably in a jewelry store with guaranteed quality.
