About, because it consists of two parts, diamond and ring, the brand cannot be generalized.
First, let's talk about diamonds.
Diamonds are not related to the brand, but only depend on its quality, that is, the parameters on the grading report. The more authoritative diamond grading institutions in the world mainly include GIA (Gemological Institute of America), AGS (American Gemological Association), HRD (Diamond Advanced Council), etc., while the domestic diamond grading agencies mainly include the National Jewelry and Jade Quality Supervision and Inspection Center (NGTC), the National Gold and Silver Products Quality Supervision and Inspection Center (NGGC) and so on. At present, the most common on the market is the GIA report, which comprehensively evaluates a diamond from four aspects: carat, color, clarity, cut, and four aspects, which is commonly known as the 4Cs. The value of a diamond is determined by the 4Cs.
(1) The weight of a diamond is usually expressed in carats (ct), 1 carat = 100 points = 0.2 grams. The average diamond proposal ring is between 50 and 1 carat, of course, if possible, you can choose a larger one.
(2) The color of the diamond is divided into colorless and colorless. Usually the diamonds on the market are colorless diamonds, and the diamond color grading is also for colorless diamonds. GIA divides diamond colors from D to Z into 23 grades, with D color being the highest and Z color being the worst.
(3) The clarity of a diamond refers to the relative degree to which the diamond does not contain inclusions (internal characteristics) and surface gaps (external characteristics). Each diamond contains a natural inclusion, like a birthmark, that represents the diamond's uniqueness and uniqueness. Diamond clarity is divided into 11 grades, which are lowered from front to back.
(4) The cut of diamonds is the only standard in the 4Cs that is manually determined. GIA divides diamond cuts into Several levels: Excelent, Very good, Good, Fair, and Poor. Descend from front to bottom.
The quality of the ring will not only affect the firmness of the diamond setting, but also affect the comfort of the wearer. A good setting of diamonds is upright and straight, the countertop is not inclined horizontally, the center stone and side stones are firmly not loosened, the height of the toothlet is suitable for the thickness of the gemstone, and the bottom support is not seen from the bottom. The ring itself is smooth and clear, the surface is smooth and scratch-free, the edges and sharp corners are smooth and burr-free, and the polish is exquisite and lustrous.
The brand of the ring is divided into international big brands such as Tiffany, Cartier, Bulgari, etc.; well-known local brands such as Fanilov. Although the classic style of the international big brand attracts the attention of most people, the price is too high to be prohibitive, and the price of the same level of diamond ring is several times higher, so if the budget is not very sufficient, it is recommended to choose a local brand.
