Celebrities Wearing Jewels
After 50 Years of Hip Hop
its Relationship with Jewellery Lives On
Aug 11, 2023

From the simple gold chains sported by the pioneering rappers of the 1970s to the bold, customized creations of the 1990s and the bejewelled “sky’s-the-limit” pieces of the 2000s, the worlds of hip-hop and jewellery have always been immutably linked.

Hip-hop's decades-long love affair with jewellery has also birthed dookie ropes, nameplate necklaces, four-finger rings and bejewelled grills.

“I’ve been telling stories with my attire and adornments for as long as I’ve been telling them with beats and rhymes,” rapper Slick Rick writes in the foreword to Vikki Tobak’s new book, Ice Cold: A Hip-Hop Jewelry History, touching on how clothing and accessories are as integral to hip-hop culture as the music itself.

There's also a great video of Rapper Hip Hop Artists 2Rare showing off his "Insane" jewelry collection!

Inspirational Design
Architectural Digest Loves Dior & Chanel
In this month's Architectural Digest (AD), one of the more obvious inspirations to be featured is Chanel’s "dazzling new Rodeo Drive boutique" that celebrates the house’s long-standing ties to Hollywood.

But another and possibly a surprising inspiration for AD is Dior’s new high jewelry that celebrates the designer’s love of the garden.

Sustainability Is About Honoring Materials
Senior Contributor

Sustainability was the main topic of discussion during the recently held “State of the Art Jewelry Summit” at Harvard University.

Well-known jewelry industry professionals joined Harvard educators to discuss the many facets of creating a sustainable industry.

Topics included detailed analysis of the sustainability of mining, designers who incorporate sustainability into their creations, ways of helping artisan miners who are often neglected in the jewelry industry supply chain, and the global consequences of not taking sustainability seriously.

Wallace Chan: The Wheel of Time
Christie’s proudly presents Wallace Chan: The Wheel of Time, the largest exhibition of works by the master jewellery artist in Europe.

Comprising over 150 pieces of one-of-a-kind jewellery creations, the display features some of the artist’s most iconic examples, including Stilled Life, an imperial jadeite brooch/sculpture that masterfully captures a cicada resting on a bamboo leaf and Metamorphosis, a stunning butterfly brooch that harmoniously combines emeralds, real butterfly wings and intricately carved rock crystal and mother of pearl. Additionally, the exhibition will feature around 20 never-before-seen works and a series of titanium and iron sculptures.

The pieces on view represent Chan’s six innovations and the significant moments of his remarkable 50-year career.
