At Cassandra Mamone, natural diamonds are our specialty.

For over 15 years, we have built our reputation on sourcing exceptional natural diamonds for engagement rings and fine jewellery, helping clients find stones that are not only beautiful on paper, but truly remarkable in real life.

While some clients seek the rarity of a colourless diamond, others prioritise size, brilliance, spread, or overall visual impact. Our role is to help you understand your options and source the diamond that best reflects your vision.

Known for our expertise in natural diamonds, we carefully assess every stone beyond the grading certificate, considering its proportions, light performance, face-up appearance, and overall beauty. This allows us to source diamonds that offer exceptional presence, including diamonds that appear larger than their carat weight may suggest.

We source from a broad range of high-quality natural diamonds, selecting each stone based on its individual merits and suitability for the piece being created.

Every diamond tells a different story. Our expertise lies in helping you find the one that's right for you.

All of our pieces are created in 9ct or 18ct yellow, rose and white gold and platinum so you can wear them for many years to come.
The main difference between 9ct and 18ct gold is the amount of pure gold in the metal. 9ct gold contains 37.5% pure gold, while 18ct gold contains 75% pure gold. This means that 18ct gold is more valuable and expensive than 9ct gold. Read more about our metals here. 

Over time, fine jewellery can become a family heirloom if it is cared for properly. Daily wear can affect the brilliance of diamonds, gemstones and metals.
We recommend a professional cleaning and check at least once a year to keep your Cassandra Mamone piece sparkling and secure. Our expert jewellers specialise in fine jewellery care, from cleaning natural gemstones and engagement rings to tightening settings and restoring heirloom pieces.
For cleaning and maintenance of all jewellery, be sure to use a high-quality polish cloth and keep all jewellery away from abrasive chemicals. As a rule, Cassandra Mamone jewellery should always be removed if it has the potential to be exposed to chemicals or knocked through daily activities.
At Cassandra Mamone, we offer complimentary first-ring cleaning for all clients and complimentary lifetime ultrasonic cleaning and in-house assessment. Ring cleaning and ring sizing turnaround approx. 5 business days.
