Based in Paris, childhood friends Kelly Souied and Kelia Toledano began Rainbow K in 2019 in a bid to update the traditional vintage design aesthetic. They create jewels to subtly accompany women in their daily lives. The designers like the association of diamonds with different noble and precious stones such as Sapphire, Emerald, Pearl or Onyx, stones that each have their virtues and meanings. Every piece is impeccably crafted in Paris, allowing the duo to keep a close eye on production.
