Some Common Mistakes When Buying Diamonds?

What are some common mistakes when buying diamonds that customers often make? Diamonds are highly valuable, and buying a low-quality product can cause losses for users. Based on experience, experts from Jemmia have identified the mistakes users make when purchasing. Let’s refer to the following content to find the answer for yourself.

Some common mistakes when buying diamonds that customers need to note

When buying diamonds, people often pay attention to the 4C standard while overlooking many other factors. Below are the mistakes customers are most likely to encounter when buying diamonds.

Fraud regarding the cut grade

First of all, there is fraud regarding the diamond’s cut grade. This is not as easy to distinguish as clarity or the stone’s color. Most customers usually overlook these points and make the following mistakes:

Figure 1: The cut directly affects diamond quality

• The seller offers 2–3 diamonds with different cut grades and persuades the customer to buy one of them. The confusion among these choices is like throwing up a smokescreen, leaving customers unsure which product to choose. To avoid this, buyers can ask the store to present all available diamonds in order to select the best one.
• Buying a diamond with a deep cut makes the stone’s weight greater than a shallow cut. Many people buy a 1.0 Carat diamond that looks like a 0.9 Carat diamond. Although this difference of only 0.1 carat seems small, the loss to the user is not insignificant, as it can amount to up to half a million VND. Therefore, it is necessary to ask for the exact weight of the diamond and avoid rounded figures used to raise the selling price.
• Diamond grading allows an error margin of one grade. For example, a diamond of color G and clarity VS2 may, upon regrading, turn out to be color H and clarity SI1. Taking advantage of this, a store may collude with the grading party to misrepresent the diamond’s color.
• When a diamond is set in a mounting, it is difficult to recognize its color as well as its clarity. Flaws on the stone will be concealed by the prongs and the reflection of light. Therefore, you should not buy a diamond priced over 2,000 USD if it has already been mounted.

Some common mistakes when buying diamonds regarding the color scale

In many cases, sellers offer diamonds that are off by one grade compared to the true color. If there is any doubt about the color, customers should request a comparison with the diamond color scale. This will help determine whether the stone’s color matches the GIA color chart or not.

You can also compare two diamonds to find differences in color. However, this should only be done on diamonds of the same shape. Because even at the same color grade, different shapes will alter the color appearance.

The lighting system in the store also increases the aesthetic value of diamonds. Blue light will make yellow diamonds emit more white light. It is best to check the diamond’s color under natural light.

Ensure diamond quality factors

For a high-value item like a diamond, there must be factors that prove its quality. This will help customers avoid some common mistakes when buying diamonds.

Guarantee policy for diamonds

Diamonds with a GIA certificate usually have higher value. Therefore, buyers should ask the store to provide a copy of the stone’s GIA grading report. This is the most accurate basis for evaluating diamond quality.

When buying diamonds, customers should ask the store to commit to a warranty policy for the product. This should specify whether there is free cleaning and diamond inspection service. Check the content carefully to understand which cases are covered under the warranty conditions.

Check the diamond’s serial number

Diamonds graded by GIA will have a serial number inscribed on the girdle. Customers need to check this number in the system to verify the diamond’s value.

Many stores intentionally obscure the serial number to avoid customer inspection. Buyers need to request that the diamond’s serial number be viewed under a machine to avoid the risk of substitution.

Above are some common mistakes when buying diamonds that buyers often make. Hopefully, this will help readers gain more valuable experience in buying and selling gemstones. And don’t forget to regularly update yourself with the latest information about the diamond market on Jemmia’s website.
