Generally, jewelry companies and sellers will stipulate that diamond rings purchased by customers cannot be replaced at will, and some fees will be charged for the old ones or discounted. This means that the diamond ring can't be renewed, but for customers who need it, they can pay the processing fee to redo it, that is, they can take their personal diamonds and rings to the jewelry processing factory for reprocessing, so as to ensure that the diamond ring they bought at the beginning is not refurbished, but brand-new.

As for the diamond ring, you can't change the style of the diamond ring at will, because it is risky to take out the diamond. Depending on the situation, you can also go directly to the physical store to ask the jewelry consultant if you can change the style.

Discount rules for diamond rings:

1, some big brands can't trade in old ones. This is the rule, there is no way.

2. There are also some brands that can be exchanged for new ones: generally speaking, only the inlaid ones can be exchanged, but the diamond ring must be higher than the original price by a certain percentage (such as 10%), which means it must be exchanged for a lower one! Then (original price change of diamond ring-original price of diamond ring) * percentage = balance to be made up,

Some brands can (original price of diamond ring-original price of diamond ring) * percentage * discount (such as 10% discount) = the difference that should be made up. There are also some brands, inlaid with pure gold (that is, K gold); Pearls and emeralds cannot be replaced with new ones.

Generally speaking, the merchants will only replace all of them, and will not give you some replacement, because it will generate additional labor costs.

4. For trade-in, at present, only trade-in sold by merchants themselves is supported, and trade-in purchased by other merchants is not supported.

There are four "C" principles in selecting diamonds: cut, color, clarity and carat weight. This is the key to identify the quality and value of diamonds.

Cutting:

Cutting is the only human factor. A skilled diamond cutter can make a good diamond shine, and he can make the internal light reflect to the surface of the diamond to the greatest extent. The cutter must cut symmetrically, just like looking in the mirror. A good mine may be abandoned because the cutter's skills are not in place.

The ideal diamond should be round, with 58 clear cut edges, which can reflect light to the greatest extent. A high-quality diamond has high value, strong reflection and symmetry, but an inferior diamond may be cut too deep or too shallow to shine.

Polishing technology will also affect the quality of diamonds. Perfect cut and symmetrical diamonds may reduce their value due to poor polishing.

Color:

In some big jewelry stores, some diamonds are displayed for comparison. They arrange diamonds of various color grades in a row to help customers compare, because ordinary customers can't tell the color of diamonds with the naked eye. The color of diamonds is colorless as the top grade, and gradually comes second with the deepening of yellow.

Purity:

Generally speaking, defects determine the value of diamonds. More precisely, it depends on the impurity content in the drilled ore. Almost every diamond contains impurities, even the best quality diamond will have some defects. When its cleanliness is LC level, it can be regarded as flawless level.

Carat:

Carat was once considered as the decisive criterion to measure the value of diamonds. When someone says that he bought a 2-carat diamond, people will find it unbelievable. In fact, the cut, color, purity and weight of a diamond are equally important to its value. The value of a 2-carat diamond with poor cutting technique, yellow color and defects is much lower than that of a perfectly cut diamond.

Transparent and pure diamonds. So the weight of a diamond is not the main factor that determines its value. The weight of a diamond still affects its value. It is important to find out whether the weight of diamonds told by jewelers is accurate. Therefore, when you buy a diamond, ask your jeweler to measure the weight of the diamond on the spot. If the jeweler doesn't want to do this, go to another store.

Mosaic:

Mosaic is also an important part. Bad inlay will cause a lot of trouble and may make the diamond fall off. So when buying a diamond ring, be sure to check whether the bracket is firm and whether the joint with the diamond is thick enough.

Shape:

There are more and more styles on the market, and jewelry designers are constantly innovating. But the more classic styles are round, oval, pearl and square. Generally speaking, the shape of a diamond does not affect its value and quality. On the contrary, it reflects the beauty of the diamond and its original shape before cutting.
