Royal Commissions from the Russian courts, Indian Maharajahs and European palaces ensued and by the early 1900s, the house already had a presence in London, New York and Moscow. After Frédéric's death in 1902, the house remained in Boucheron family hands for almost a century and is today owned by PPR who have continued the international expansion and boundary-pushing ethos, be it through the appointment of Solange Azagury-Partidge as Creative Director, collaborations with rising designers such as Shaun Leane, or with high profile stars such as Alexander McQueen. 寶詩龍寶詩龍（Boucheron）由Frédéric Boucheron在1858年創立於巴黎，是最早一批在傳奇Vendome廣場開店的珠寶商，店址位於26 號，至今仍是寶詩龍（Boucheron）的全球總部。因有俄羅斯，印度及歐洲皇室貴族的訂做生意支持，早在1900年代初，已在倫敦， 紐約和莫斯科設立了分店。Frédéric於1902年去世，品牌當時已在寶詩龍（Boucheron）家族手中有近百年歷史，時至今天，品牌現已屬PPR旗下，並繼續拓展國際市場，尋求突破，其中包括通過任命索朗芝 ∙ 阿薩古力-帕特裡奇（Solange Azagury-Partidge）擔任創意總監，及肖恩 ∙ 利恩 （Shaun Leane）等新興設計師,及與亞歷山大 ∙ 麥昆（Alexander McQueen）等知名明星合作。
