Jewellery. Personalise it.

Avant Studio’s vision is to make jewellery a personalised statement. Our jewellery sets intention for the wearer.

Pieces that encapsulate your essence. Pieces that remind you of a precious time. Pieces you can gift to someone special.

Customisation is at the forefront of Avant Studio. Many of our styles have the ability to become a bespoke piece.

Create your own uniquely personal piece.  



Avant Studio has 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.

We 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 biodegradable materials. Our current initiative incentivises the return of their jewellery box packaging for a $15 voucher/box. The boxes will then be recycled or repurposed with an aim to reduce further production. We also collect faulty or old pieces and recycle them to become a part of future collections. 

One of our goals each year is to support and represent a different cause in need. In 2020, we chose to support the NAAJA (North Australian Aboriginal Justice Agency). We are working on constantly educating themselves and researching causes which are in the most need. 



AVANT STUDIO was founded by best friends Belle Maartensz and Briella Brown in January 2020.

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 business, Briella and Belle have aspired to create a unique online lifestyle brand with strong values at its foundation.
