About Us


We are a 100% Australian owned Perth based family run business.

Our passion is to provide our beautiful, beach loving, industrious, bold and playful country with Jewellery designed by us and inspired by the beautiful landscape that surrounds us, drawing on elements from our stunning coastline, expansive oceans through to our rugged and breathtaking interior, combining all these elements to create an alternative style that embraces individuality with subtle twists to classic Jewellery.

Our future will see a move away from the Fashion industry standards with real (un-edited) women in campaigns and aims to confirm itself as a leader in ethical manufacturing and sustainability.

We are passionate about our Ethos and Ethical approach to production and will work to continue to develop our sustainability. All our packaging is either recycled, re-usable or biodegradable to ensure your treasured pieces have as little impact on the planet as possible.

Our Jewellery is never mass produced with most collections containing only limited numbers, we believe this allows for an element of affordable bespoke design. 

We are proud to offer unique hand-made Silver plated jewellery, that is 100% recyclable.



Raw material producers are carefully chosen for their ethical approach, Eco-friendly production and waste management methods. The components of our jewellery are handmade by skilled Jewellery workers in a safe and happy working environment.

Pioneering the use of .925 Silver plating onto an Aluminium core we achieve a beautiful, burnished silver which is both hard wearing, durable and the trademark finish that makes our Jewellery so unique.

Our traditional production method has been used in Turkey for hundreds of years.

Made without the use of harmful metals commonly used all over the world like Lead, Nickel or Cadmium, Trelily Jewellery is particularly suitable for customers who may be allergic to these base metals.



We believe our customer is Queen.

We strive to offer the best, no-quibble returns policy in the business.

If your not entirely happy with your purchase we will refund or replace - no questions asked.

With all of that in mind, why not indulge yourself in a conscientiously produced  piece.
