Second, shop around. But the premise is to see clearly the quality of diamonds and the workmanship of jewelry. The price of diamonds is relatively stable and transparent, so you can consult experts before buying. It is best to buy in a stable and reputable store or shopping mall, because after-sales service is also an important link.
3. What kind of diamond is the most valuable? Above 1 carat, the price is reasonable, and the most valuable is the appraisal certificate from international authoritative organizations such as GIA or HRD. The price of this kind of diamond has been rising steadily, and it won't lose much whether it is made into a family heirloom or realized by auction.
Fourth, it helps to understand the "4C" openness. Although the "4Cs" of diamonds-weight, clarity, color and cut-are commonplace, it is beneficial to ask more questions when buying. For example, ask "how clean" and "what color level", and the store will understand that you are a knowledgeable person.
Fifth, there is a coup to change the decoration. Diamonds are the main value of diamond ornaments. You can get a new diamond ornament at a very low cost, if you replace it and put it back on. Nowadays, the service measures of many jewelry stores are that you can exchange jewelry with little money. This requires you to cherish your diamond ornaments and not to damage them.
