Treat Yourself This Weekend!

There’s so much to look forward to this weekend, and it’s all in celebration of YOU, mom!

Discover our newest pieces from Todd Pownell, Maria Beaulieu and Yossi Harari.


And as if that weren’t enough, we will be hosting our first ever Julez Bryant Trunk Show!

Organic designs, inspired by the world’s natural beauty, are the embodiment of Julez Bryant’s collections. The raw and elegant forms of these pieces are perfect for everyday wear. Discover, through Quadrum’s first ever Julez Bryant Trunk Show, the grounding elements this handcrafted jewelry has to offer. Meant to be layered and layered again, this is a collection built on the foundation and belief that women should always feel empowered and sexy in what they wear. So start mixing bold shapes with luxe materials (think 18K and 14K rose, yellow, and white gold with the finest and most exotic cuts of diamonds and semi-precious stones) and curate your own personal collection. Truly one of a kind, this special event promises to be an exciting one!
Saturday May 13, 10AM- 6PM
Sunday May 14, Noon- 5PM

See you this weekend!
