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

Or, purchase our Ring Sizer which can be placed around your finger, providing the correct size.
