Diamond is one of the two best known allotropes of carbon (the other is graphite), with very high hardness and excellent refraction. So how many types of diamonds are there and how are diamonds priced? Together C Jewelry Diamond learn how diamond classification in the article below.

Classify diamonds according to 4C standards

  • Color – color

A diamond will have a higher value if it has a clearer color and is free of impurities. If a diamond is mixed with yellow dots, it will have the lowest value. Because yellow and brown are more common, diamonds of this color are also less valuable. But on the contrary, diamonds mixed with blue or pink are valued many times higher. According to diamond appraisal experts, depending on which element the carbon crystal is replaced with, the diamond will take on the color of that element.

  • Diamond Plate
  • Diamond jewelry

  • Carat – weight

The size of the diamond can significantly affect the value of the stone and diamond jewelry. In general, the larger the diamond, the more valuable it is. Diamonds are divided into carats and ponits with 100 points = 1.00 carats (according to the US currency system). Remember carat weight refers to weight, not to be confused with the size of the diamond (diamonds are measured in millimeters). You should care more about what a diamond looks like than how much it weighs if you want to pay for beautiful diamonds rather than heavy ones. Below is the weight classification of diamonds and the ratio between size and weight to help you define the diamond you want to own.

  • Clarity: Clarity

Diamond appraisers will use a 10x magnifying glass to magnify the diamond so that all flaws in a diamond can be seen. From cracks to scratches, blurred spots or poor dispersion. Among the criteria, clarity is considered an important standard in diamond valuation principles.

  • Cut – the cut of a diamond

A diamond's cut is a guide to the style or design used when shaping a diamond for polishing without reference to the shape of the diamond. Buyers often consider the shape and appearance of a diamond and its ability to shine however cut here refers to the symmetry, balance and luster of a diamond and its effects. to its luminosity. This means if it is poorly trimmed it will shine less.

Cut refers not only to the shape of the diamond (e.g. round, oval, pear shape) but also to the diamond's symmetry and luster. The beauty of a diamond depends more on its cut than any other factor.

A quality, precious diamond is said to be cut in a circle with 57 slices including: 33 facets are used to scatter light, the remaining 24 facets are responsible for reflecting light to bring the most brilliance.

Some common mistakes when buying diamonds

Normally, when customers want to buy diamonds, they often choose familiar stores to buy, even when they buy online. Customers are often interested in different parameters of diamonds such as size, weight, shape. In case of buying diamonds from local stores, you should note the following points:

The most common mistake when buying diamonds is cheating on the quality of the cut. The cut is a very difficult point to distinguish from the color and clarity of the diamond, so you often ignore this point. Common errors are:

Stores only show customers two or three diamonds with different cuts and try to convince them to buy one of them. Meanwhile, shoppers can choose the best diamond that they like. If you ask them to give you all the diamonds they have. This is the simplest but best way for you to buy a satisfactory diamond at a certain store.

Buying a diamond that is cut too deep, a diamond that is cut too deep is usually heavier than a shallow cut diamond. You could buy a 1.00 carat diamond that looks just like a shallow cut 0.90 carat diamond because it was cut too deep.

Diamonds with a perfect cut can be much more expensive than diamonds with a poorer cut. Therefore, poorly cut diamonds are often cheaper, less likely to be in inventory, and sell more. Therefore, sellers often import this type of diamond.

Another problem is that customers cannot recognize the color and clarity of the diamond if it is placed in the ring. Flaws in the diamond may be hidden underneath, the color may be obscured by its reflection. You should not buy a diamond over $2000 without having it inspected before it goes into the ring. No retailer, dealer or wholesaler will buy a high-value diamond once it has been set into a ring, so you should not do this.
