Custom Jewellery Design
Unique jewellery designed and made in Sydney
I would love to create your dream piece of jewellery come true as I believe that anything is possible.
As a gemologist, I can source and recommend suitable gemstones to create unique jewellery pieces. 3D CAD designs that generate photo realistic renderings are created and refined before the piece is created. You’ll be consulted during the process and will be part of the custom jewellery design process.
We can start a design for you from any way you prefer – have you got a favourite gemstone in your collection or perhaps an idea which you’d like to bring to life? Then contact Maria by filling out the below Contact Form or Call to book your free design consultation by calling 0481 357 691 and let’s get it started bringing your dream custom design jewellery piece to life! Consultations are by appointment in person in our Sydney showroom located in the CBD.
