Established in January 2020, Avant Studio’s vision is to make jewellery a personalised statement. Our jewellery sets intention for the wearer.

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

Personalisation is at the forefront of Avant Studio. We design many of our pieces to offer our customers the gift of choice in imagining and creating their own customised pieces.



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 extremely passionate about environmental sustainability practice. From the conception of Avant Studio, our packaging has been proudly 100% plastic free.

All elements are made of recyclable paper and biodegradable materials. Our current initiative incentivises the return of our 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. 

Something extremely important to us is to use our position to give back and provide support to those in need. One of our goals each year is to support a different cause in need. In 2022, we have chosen to contribute to UNHCR for urgent aid on the ground with the war in Ukraine, as well and the Northern Rivers Flood Relief to support families left devastated by the floods in Northern NSW and QLD.  


AVANT STUDIO was founded by Belle Maartensz in 2020.

In 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 boutiques across Australia.

Combining her experience in fashion design and a passion for brand building and business, Belle has established a unique online lifestyle brand with strong values at its foundation.

She has always hoped to build a community of women that share her mutual passion for business, design and empowering each other.
