Explore our Sydney showroom on Castlereagh Street for a personalized shopping experience and in-depth jewellery education. When purchasing a diamond, clients can use a jeweller’s loupe to discover the 4 Cs of diamond grading—cut, color, clarity, and carat weight—and view examples of each quality level.
To ensure the highest standards, every diamond we offer is certified by both the GIA and the DCLA laboratory, providing our clients with absolute authenticity and peace of mind.
Book an AppointmentI was introduced to Mark through my insurance company as I’d lost the diamond in my engagement ring, and I couldn’t have asked for a more professional, caring and trustworthy jeweller. He went above and beyond sourcing the right diamond for me.
He also liaised with the insurance company which saved me a lot of time and anxiety. I’ve since used Mark for some further repairs on another ring and have had verified valuations. I look forward to using Mark for all my jewellery needs in the future.
Nothing but compliments for Mark.
He was thorough and patient to help me design the wedding bands for my partner and I. Knowledgeable and detailed in helping us choose rings that was a comfortable fit and also matching her wedding band to the engagement ring.
Highly recommend for your jewellery needs
From the moment we first contacted Mark Nathan we experienced the most professional and personal service. We brought with us very sentimental family jewellery to be redesigned into our engagement ring. It was such a wonderful and exciting experience working with Mark who has so much passion and knowledge that we knew our stones were in great hands. Mark has incredible attention to detail and created a piece that captured our vision perfectly.
Thank you Mark so very much for your dedication and hard work. We’ll be seeing you soon to design our wedding bands!
