Kourtney Kardashian partnered with her sisters Kim and Khloé to create three new perfumes for Kim's brand KKW Fragrance.

Kourtney Kardashian, Kim Kardashian, and Khloé Kardashian collaborated on the KKW Fragrance Diamond Collection in November 2019, releasing a trio of jewel-inspired perfumes packaged in crystal-shaped bottles. The collection officially launched through KKW Fragrance as part of Kim Kardashian’s expanding beauty and fragrance business and marked one of the sisters’ most prominent fragrance collaborations together. The Diamond Collection featured three separate scents, each associated with one of the Kardashian sisters and designed around distinct fragrance profiles. Kourtney Kardashian’s fragrance, Yellow Diamond, was described as a sparkling oriental gourmand featuring notes of golden berries, yellow jasmine, magnolia, vanilla, and patchouli. Khloé Kardashian’s Pink Diamond centered around floral and musk elements, including transparent musk, pink tuberose, jasmine, and lilac. Kim Kardashian’s fragrance, simply titled Diamond, combined tropical floral notes with wild armoise, white musk, and patchouli to create a fresh floral musk scent. The perfumes were released in faceted bottles designed to resemble large-cut gemstones, continuing the luxury-inspired aesthetic commonly used in KKW Fragrance packaging. Promotional campaigns for the launch featured the three sisters posing together in diamond-themed imagery that was widely shared across social media and beauty publications. The collaboration also reflected the broader strategy behind KKW Fragrance, which frequently partnered with family members and celebrities to create limited-edition collections tied to recognizable public identities. At the time of the release, celebrity fragrance brands remained an influential segment of the beauty industry, with social media marketing playing a central role in product promotion. The Kardashian family’s global online audience helped generate extensive visibility for the Diamond Collection shortly after its announcement and release. Beauty media coverage highlighted both the gemstone-inspired presentation and the individual scent profiles connected to each sister’s personality and branding. Editorial Note The Diamond Collection illustrated how celebrity fragrance launches increasingly blended luxury-style packaging, personal branding, and social media promotion during the late 2010s. By assigning each sister a distinct scent identity, the collaboration also reinforced the Kardashian family’s approach of combining shared branding with individual public personas.
