What is RGG certification?

RGG certification is one of the diamond quality certifications trusted by people in Vietnam. RGG is the Gemstone – Gemology Research Center under the Vietnam Science Institute.

RGG started as an appraisal department named Rexco, established in 1995. After more than 5 years of operation, the unit was renamed RGG. The purpose of the certification unit is to ensure consumer rights.

The RGG certification center applies the 4C standards of GIA to appraise diamonds. All machinery used for certification are advanced equipment. The GIA Gemological Institute is the manufacturer of specialized equipment for testing and appraising the quality of precious gemstones.

RGG Certification Certificate

The RGG diamond quality certificate is issued by a domestic organization. It has no value internationally but is only circulated in Vietnam. If you only need to use and trade diamonds in Vietnam, choose RGG.

The content in the RGG certificate provides complete information to meet customer needs. You will see clear photos of the certified diamond.

People will read detailed information about the diamond, including:

• Weight
• Dimensions
• Diamond type
• Cut style
• Clarity
• Color
• Long wave
• Short wave
• Related comments
• Appraisal methods: refractometry, specific gravity, microscopy, UV and visible light

Each piece of information is 100% accurate with the appraisal results.

What are the characteristics of RGG-certified diamonds?

Diamonds that have undergone quality certification will have a unique serial number. The serial number will be recorded on the certificate and on the diamond. If both parameters match, the diamond has been quality certified.

Previously, Vietnam's technology was not as developed with modern machinery. RGG used to seal certified diamonds with their serial numbers. Consumers could easily and quickly identify and distinguish the quality of diamonds. The seal contains all the basic information of the diamond.

Sealed diamonds lose their external aesthetic appeal. Therefore, RGG has developed laser engraving technology on the diamond's girdle. This new development by RGG is highly appreciated by many customers.

Above all, it ensures the highest accuracy. Exclusive techniques provide domestic diamond enthusiasts with absolute peace of mind.

How is RGG certification done?

If you buy or want to trade diamonds in Vietnam, you must have a transit permit. You can use the original certificate issued when you previously purchased the diamond.

In case the diamond's certificate is lost or outdated, you can request a renewal. The fee for RGG certification upon request is relatively low. Fees are divided into different levels based on the color of the gemstone. The reference price for everyone is from 200,000 VND for one certification.

In addition, the time for one RGG diamond certification takes from 3 to 7 days. You need to consider the time to suit your need for certification at RGG.
