FINEST DIAMONDS

At Cassandra Mamone, we only use naturally mined diamonds and gemstones in all our pieces. 

Diamonds can be classified according to the 4 Cs – cut, colour, clarity and carat weight. The combination of these four factors determines the value of a diamond. Every diamond is unique. We abide by a very strict diamond sourcing criterion to ensure we only source highly graded diamonds. All centre diamonds used in our engagement rings are individually sourced and hand-set to ensure the highest quality. Diamonds that are above 50pts (0.50ct) will have a GIA certificate. Cassandra Mamone only sources diamonds SI1 and above in clarity, F and above in colour, with no fluorescence and a minimum cut grade of Very Good. 

* Please note all online purchases of diamond engagement rings will be F in colour and SI1 in clarity. If you would like a diamond higher in clarity and/or colour, please email us for a custom quote at design@cassandramamone.com

As all of our pieces are made to order (except sterling silver) we do not accept exchanges or returns for change of mind. 

Cassandra Mamone offers a lifetime manufacturing warranty on custom pieces. If the issue is due to manufacturing, Cassandra Mamone will cover any repair or replacement fees.

Normal wear and tear is not covered by our warranty. 

You are also entitled to a free first cleaning and inspection by our design consultants. 

Please contact us via email or schedule an appointment if your piece requires repair or services. Our design consultants with assess pieces on a case to case basis. 

Your warranty will be voided if your piece has been polished or resized by another jeweller other than Cassandra Mamone.
