An independent diamond certificate is the best guarantee of your diamond’s quality and value. At All Diamond, almost every diamond we sell is accompanied by a diamond certificate from the world’s leading independent diamond certification organisation, the Gemological Institute of America (GIA).
Although we work only with the GIA because they are the best, there are some other certification laboratories you might have seen. Click below to find out more about the diamond grading and certification organisations you are most likely to see.
