Diamonds are classified according to 4C standards, namely, color, cut, clarity and weight. The color grades of diamonds are divided into 23 grades, such as D, E, F, G, H, I and J. Colors range from transparent to yellow. The more transparent the diamond, the higher the grade. The highest grade is D drill, and the lowest grade is Z drill.

Diamond cutting refers to the cutting process, which is divided into five grades: EX, VG, GD, F and P. Under the same other 3C standards, the more perfect the diamond cutting, the smoother the lines and the higher the grade. The highest grade diamond is EX diamond, that is, perfect cut diamond.

Diamond buying skills

Before buying diamonds and diamond ornaments, you must make a purchase budget in advance and do what you can. If you want to buy bigger diamonds under a really limited budget, Bian Xiao suggested that you can choose diamond jewelry with poor clarity but high color.

For many jewelry stores or diamond stores, festivals or celebrations are generally used to do some special promotional activities. Therefore, consumers may wish to pay more attention to the advertisements in newspapers and magazines before buying diamonds, so as to help them choose the best time to buy diamond jewelry.
