Gemstones

Welcome to the exciting and beautifully vibrant world of coloured gemstones.

Here at the Certified Diamond Network we have a long history of professional experience and passion for coloured gemstones. They are the inspiration and starting point for the majority of our bespoke, designer rings & custom jewellery designs that are created in our studio workshop in Parramatta.

We are constantly excited and inspired to source the most beautiful gemstones from Australia and around the world for our clients.

If you’re looking to buy a loose gemstone in Sydney, then look no further… As your personal gemstone broker, we can access some of the most beautifully coloured and rare gemstones for you at a wholesale level, ensuring not only a wide range of choices but also the most competitive price.

To help you understand the differences and unique qualities of some of the better known gemstones that are used in a range of custom jewellery designs, we’ve compiled some helpful information as well as images to guide you on your journey.
