Giving Back to the World We Love

As ocean and nature lovers first and foremost, we strive to run our business as a reflection of our values and those of our customers. This means making 100% of our jewellery here in Australia rather than overseas, utilizing responsible and sustainable materials, and giving back to protect the earth we love.

As a member of 1% For the Planet, we donate a portion of every sale towards environmental causes, meaning your purchase helps to protect and preserve our beautiful planet for future generations.

"Alana and Nick have been absolutely incredible! They guided my partner in designing the most beautiful engagement ring. The process of resizing the ring to fit me perfectly has been so easy and fast! I can’t thank them enough for their exceptional service and attention to detail. Thank you!"

"World Treasure Designs make my favourite ring in the world, the silver whale shark. I had one a few years back that I treasured but lost on holiday, I recently was gifted the same ring again since I missed it so much. I needed it resized and Allison was so helpful and I was able to send back my ring and get the right size returned to me really quickly and easily. Love love love your service and your products – thank you."

"A heartfelt thank you to Nick, Loretta and the team at World Treasure Designs for my new unique, one-of-a-kind ring. The craftsmanship that went into the design makes the ring a work of art which I’ll love and admire forever. The team’s attention to the smallest detail is what takes your business one step above other jewellers. It’s an absolute pleasure to deal with such a professional and friendly team."

"Absolutely in LOVE with their jewelry. Excellent customer service and actually slightly modified my leopard shark necklace to put a nick in the fin to look like the same shark me and my girlfriend bonded over. Would recommend 100% to any marine lovers, their pieces are great quality and you won’t be disappointed!"
