While the natural diamond industry initially sought to undermine public confidence in engineered jewels, several high-end designers took early initiative to harness ethical lab diamonds and moissanite in premium collections - lending runway credibility.Among the first movers was couture house Chanel, debuting a fine jewelry collection featuring cultured diamonds as early as 2007 when prices still approached $4,000 per carat. Their embrace was a turning point in positing lab-grown gems as genuine luxury contenders, given the maison's authority crafting diamond symbols of desire since Coco Chanel’s 1932 Bijoux de Diamants.Likewise Bulgari unveiled a parent company-backed mass-produced CVD diamond subsidiary in 2016 to widespread market fascination - legitimizing technological ingenuity elevating diamond creation.Meanwhile Tiffany & Co, having trademarked and mainstreaming the legacy solitaire, took until 2018 to unveil transparent lab diamond debuts after initially berating the sector. But their pivot indicated to shoppers that peak American luxury now sanctioned sustainable science in gemology.So elite early adopters shaped attitudes and unlocked lab-grown desirability, accelerating market uptake exponentially. What were once coded plastics are now recast and rebranded as apex sustainable gemology thanks to their bold early faith in pairing Green with Glamour.
