AVANT STUDIO was founded by best friends Belle Maartensz and Briella Brown in January 2020. Both with a background in fashion and entrepreneurship, they established Avant Studio with the vision of creating an online destination for a curated collection of jewellery and accessory designers. Their vision was to create a unique aesthetic platform to allow every woman the opportunity to find pieces that will elevate the every day.

The platform showcases both Australia’s and the world’s most coveted brands as well as under-the-radar emerging designers and artists. 

Shortly after launching, Belle and Briella released their in-house collection, Avant by Avant Studio. The collection was designed to provide classic every day essentials and timeless pieces for every woman.

One of the brand pillars of Avant Studio is to harbour the intention of thoughtful gifting. The gift of giving allows an opportunity to connect with others. One of the aims of the platform is to take the guess work out of finding a meaningful token for someone special.



Belle and Briella started their journey with a present consciousness for female empowerment, environmental responsibility, social justice and supporting local and international communities. Avant Studio was established with strong values and positive messaging at its core.

“Jewellery is like the perfect spice, it always complements what’s already there”

- Diane Von Furstenburg

The effortless action of adorning yourself with a simple piece of jewellery can immediately transform mood and attitude and forces the recognition and appreciation for what lies underneath. This notion of self love, confidence and empowerment is deeply engrained in the base of the brand.

They are also extremely passionate about environmental sustainability practice. Avant Studio’s packaging is proudly 100% plastic free. All elements are made of recyclable paper and cardboard and the freight satchels are plant based and 100% biodegradable.

One of their goals each quarter is to support and represent a different cause in need. During their first quarter, they chose to support the NAAJA (North Australian Aboriginal Justice Agency). They are working on constantly educating themselves and researching causes which are in the most need. 



Briella and Belle are both native Sydney siders. They attended university together where their mutual passion for fashion and business led them to their individual careers and success in the fashion industry.

Briella launched the acclaimed designer dress rental business YOUR CLOSET in early 2014. Shortly after, she successfully pitched her business idea on Australia’s Shark Tank. Following the success of the show, YOUR CLOSET has been featured in publications such as Vogue, ELLE and Sydney Morning Herald. Briella was a guest speaker on the Business Chicks panel in 2017.

In Mid 2015, Belle established the women’s clothing label THE A-LINE, with a focus on femininity through luxurious fabrics, sleek finishes and timeless silhouettes. The label's debut collection launched in 2015 and was stocked in high end boutiques across Australia.

Combining their complementary skillsets and passion for brand building and entrepreneurship, Briella and Belle have aspired to create a unique online lifestyle brand with strong values at its foundation.
