Product integrity is key for us. Hence, we have our diamonds certified by reputable, third-party, gemology laboratories such as the Gemological Institute of America (GIA), the International Gemological Institute (IGI) and the HRD (Hoge Raad voor Diamant), assuring international standards relied upon by all traders, retailers and consumers. As a Forevermark diamantair, we take the product integrity to the next level. Not only the quality of our craftsmanship is certified but our full manufacturing process is monitored. Both our factories are independently assessed and comply with the rigorous principles of the Forevermark program.
