First of all, buying jewelry design is not only a matter of raw materials, but more importantly, the designer's creativity. Only classic styles can last forever. Secondly, it is very important to make good use of its shape. Coordinated proportion and proper modeling design can amplify the material value of the designed jewelry several times or even dozens of times. Finally, color matching is a deep knowledge in jewelry design. Excellent color matching can add a lot of color to ordinary design, while disorderly color matching will discount the value evaluation of well-made works.
