The difference between GRA , GRI and customs certificate
Many customers don't understand the difference between our product certificates. Let's explain the difference between GRA certificate, GRI certificate and customs certificate.
GRA is a third party organization based in Hong Kong that provides certificates in a variety of appearances and configurations. We will randomly match loose Moissanite provided by the raw material factory.
GRI is a moissanite detection institution newly established in recent years. Its function is the same as GRA. We will configure it in colored loose moissanite.
The certification certificate issued by the general administration of customs is issued by the industrial product testing technology center of the customs, which represents the quality and standards recognized by the customs of China. We will only use this certificate in the sale of loose moissanite of "Special Selection" to ensure that the product has a high level of official certification.
