Designer collaborations in clothing is nothing new.  Target has Jason Wu, Marc Jacobs and Marchesa collaborations in the pipeline and H&M has paired with Lanvin in the past and is rumored to be collaborating with one of my all time faves, Maison Martin Margiela this year.  Fine jewelry retailers are also getting on the designer collaboration bandwagon in an effort to sync up fashion and fine jewelry.  Here are some of the most SWOON-worthy designer jewelry collaborations that have caught my eye:

Blue Nile and Monique L’huillier

Online jewelry retailer, Blue Nile, known for its well-priced, customizable jewelry is revamping its image to become more fashion-forward.  The online retail giant’s newly announced collaboration with Monique L’huillier, a high-end clothing designer with a strong bridal business is pure strategic genius.  The Monique L’huillier fine jewelry line will launch exclusively on Blue Nile in October and will consist of engagement rings and wedding bands that range in price from $2,000-$5,000 with additional earrings, pendants and necklaces to be unveiled in time for Valentine’s Day 2013.  The pieces that I’ve seen thus far reflect the designer’s eye for detail and romantic aesthetic beautifully.  Discerning brides take note!

Kenzo Takada for 10 Royale

Japanese designer Kenzo Takada, of his eponymous label, Kenzo, is collaborating with Parisian jewelry atelier 10 Royale on a line of 20 pieces of fine jewelry using white gold, diamonds and rubies.  The pieces will reference Takada’s trademark aesthetic of florals and patterns and be centered around the theme of “floral blooming.”  It is reported that 10 Royale intends to collaborate on jewelry lines with a different designer every year.

Philip Treacy for Voltaire Diamonds

London-based milliner, Philip Treacy, famed for his avant-garde creations will collaborate with Voltaire Diamonds on a line of engagement rings and bridal jewelry to launch on Valentines Day, 2013.  If his jewelry is anything like his hats, the pieces will speak to a very adventurous demographic of women with a sophisticated eye for design and modern sensibilities.  Can you think of anything more divine than a Lanvin wedding gown paired with a Philip Treacy engagement ring?  See my full post on the collaboration here.
