Certified Diamond Network

A First Class Experience at Certified Diamond Network

We understand how important trust is when purchasing,


Once you have decided on your gemstone shape, book a visit to our showroom and sit down with one of our industry insiders or diamond jewellery designers to discuss your white or fancy colour stone expectations and budget for the ring. Australia has some of the finest quality wholesale diamonds and gemstones in the world; we will browse through 85% of the loose diamond inventory to source gemstones that are uncompromising in their visual qualities. Once we have chosen your top 3-5 precious gemstones, we will have them sent to our design studio where we will personally visually critique each loose diamond or gemstone under grading conditions, in order to give you all the information you need above and beyond their generic technical details to make an informed and educated decision.
