6. Graff
Graff is a British jewelry brand founded in 1960. The brand’s pieces of jewelry are known to feature huge gemstones. What makes Graff’s collection special is not just the the quality of the gemstones and metals used to create exquisite pieces but also the size of the stones the brand uses for its jewelry line. Laurence Graff himself has said that large stones, especially huge diamonds, are what he is all about.
Graff adheres to the Kimberly process, never knowingly buying or trading rough diamonds from areas where it would encourage conflict or human suffering.
The majority of Graff diamonds are laser engraved with unique Gemological Institute of America tracking numbers, which whilst invisible to the naked eye, allow for its origin to be traced.
