Andrew Ralph’s Diamond Jewellers has been in the Mandurah region for more than 37 years. 

Andrew developed his passion for jewellery, working with his father from a young age and has continued this to become a Gemmologist, Registered Valuer and Diamond Grader. Along with his helpful and knowledgeable team he offers quality jewellery, the most ethical, popular and trusted brands, jewellery design, personalised diamond brokerage service, manufacture and remodel services and an after-sales service that is second to none.

In October 2020, Andrew sold his retail store front, allowing more time to commit to one on one customer appointments, bespoke jewellery designs and valuations.

As Andrew is a registered valuer, diamond grader and gemologist you can be assured you are getting the best advice and information throughout your experience.

We also offer Jewellery repairs and remodelling which are carried out in our local  workshop. Whether it is a simple chain repair or designing a bespoke piece of jewellery Andrew can source gemstones and take you step by step through the process.

For more than 30 years Andrew Ralph’s Diamond Jewellers has been and remains the region's most trusted jeweller.
