The choice of diamonds

The selection method of diamonds is as follows:

1, depending on size

Diamonds with the same color and similar purity, the bigger, the more precious. Diamonds weighing more than 3 carats are expensive diamonds, and diamonds weighing more than tens or even 100 carats are world-famous diamonds. Because diamonds are expensive, there are many things that fake goods or various artificial techniques cover up shortcomings and raise the grade, so it is extremely important to identify the authenticity of diamonds and distinguish their quality grades (color, purity, etc.). ).

2. Look at this color

It is very important to judge the quality of diamonds from their colors. Generally speaking (except colored diamonds), diamonds are colorless (white), light yellow, light yellow and yellow, among which colorless, transparent and pure as water is the best. Judging the quality of jewelry from diamond raw materials to processing, the whiter the diamond jewelry, the better, the crystal is transparent and pure, the workmanship is good, and it is suitable for new workers.

Step 3 look at the purity

Diamonds with high crystallinity, complete transparency and no defects have high purity. The higher the purity, the more valuable the diamond is. To check the purity of diamonds, it is often necessary to use a magnifying glass more than 10.

Step 4 watch the work

A rough diamond is just an ordinary stone. Only through accurate calculation, careful design and perfect cutting can the light fully reflect the top surface, which depends on the quality of workmanship (cutting).

Pick up the diamond and stare at the jumping light at the top. Exquisitely cut diamonds are dazzling, and the fire will not disappear because of different inlays or styles. The grades of cutting are: perfect, very good, good, average, etc. For larger diamonds, you can use a cutting mirror to check the quality of work.

Step 5 read the certificate

You must see the certificate when you buy diamonds. The appraisal certificate of diamond ornaments is equivalent to its ID card. Only by looking at the certificate can we determine the accurate specifications of the diamond such as color, clarity and cut. Different merchants will provide users with various authentication certificates. In terms of professionalism and strictness, the national inspection/international certificate > provincial certificate > municipal certificate > other commercial certificates, and the professional and strict appraisal certificate will make the diamond ornaments have better quality assurance and are genuine products.
