The story of diamond prices after resale is always one of the topics that receives the most attention. In reality, some people who wear diamond jewelry for a period of time will want to resell it, while others buy diamonds for storage. So how different are the purchase and resale prices of diamonds? Please spend a few minutes following the article below.

The familiar story of buying and reselling diamonds

Diamonds are gemstones with high economic value. In addition, this gemstone also has many applications in life such as: making electronic microchips, cutting and grinding tools, polishing… Only 30% of mined diamonds are used in the jewelry industry.

Some people who wear diamond jewelry after a period of time have a need to resell it or exchange it for newer, more beautiful designs, or more expensive jewelry pieces. Normally, when reselling, the seller will have to bear a certain loss. This is because the selling price of diamonds usually loses part of the discount compared to the purchase price.

However, in general, diamond prices on the market fluctuate less than gold prices or the dollar exchange rate. This price increase or decrease depends on customer demand and mining supply. For that reason, there are still people who buy diamonds as assets for storage instead of gold thanks to their good liquidity.

Factors affecting diamond prices

What factors affect diamond prices when reselling?

This is certainly a question that concerns many people. Diamond prices when resold are usually not as high as at the beginning. So what factors affect diamond prices when reselling? Let’s take a look at some of the following factors:

Diamond certification

Does the diamond have certification papers or not? Many people still think that this factor does not affect the selling price of diamonds. Because according to diamond price lists on the market, its value is evaluated based on the 4C criteria including: Weight number (measured in carats), the perfection of the cut, color, and clarity.

However, in reality, for diamonds with certification papers, the depreciation when resold is usually lower. Between domestically certified diamonds and internationally certified diamonds (for example, a GIA certificate), the selling price also differs.

Diamonds with certification papers are often sold at higher prices

Diamonds with certification papers are often sold at higher prices

The reason is that domestic certification currently only stops at blister-pack certification. When the diamond is removed from the blister pack, its value also loses verification. Meanwhile, for GIA diamonds (Gemological Institute of America), a code is engraved on the girdle of the gemstone. This code corresponds to the number recorded on the certificate. Because the characteristics of the diamond have been verified and guaranteed, the selling price is usually a bit higher.

Wear and tear during use

After a period of use, if not properly preserved, diamonds can become scratched. Dust and grease stains on the surface make the diamond look dull and reduce its value.

Where should you resell diamonds to get the best price?

If you want to resell diamonds, it is best to choose the store where you originally purchased them or other branches in the same chain. When selling at these addresses, the discount rate for customers is usually more favorable. Especially when buying diamond jewelry products, you should pay attention to the store’s buyback and exchange policies to protect your own interests.
