    • Radiant centre diamond
    • 1.5pt champagne round brilliant diamonds
    • Polished gold finish
    • Claw setting
    • 1pt diamond halo
    • Knife-edge band 
    • 1/2pt half-set diamond band and arm setting

Setting Option A - the setting goes straight down to the finger, when choosing your wedding band you will need to opt for it to be fitted - it will be custom made to sit around the setting

Setting Option B - the setting arms sit up on the band allowing a 1.8mm space for your wedding band to sit flush, underneath the engagement setting, ensuring if it's 1.8mm thick, it will not rub against your setting. This allows options for wedding bands to be almost endless. 

This beautiful piece is hand-crafted and will take approximately 4-6 weeks for completion. Timeframe not including delivery.

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. All centre diamonds used in our engagement rings are natural diamonds, GIA certified, individually sourced and hand set to ensure the highest quality. Cassandra Mamone only sources diamonds SI1 and above in clarity and F and above in colour.


* 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 colour, please email us for a custom quote at design@cassandramamone.com




Cassandra Mamone only sources natural colourless diamonds from the top 3 colour grades D - F ensuring that your piece will reflect the brand's timeless and classic nature. Every diamond is unique. Diamonds that range from colourless to light yellow fall within the normal colour range. Within that range, colourless diamonds are rare, making them the most valuable. Subtle differences in colour can dramatically affect diamond value. Two diamonds of the same clarity, weight, and cut can differ in value based on colour alone. Even the slightest hint of colour can make a dramatic difference in value.





Champagne diamonds are well established in Cassandra Mamone’s brand since its inception in 2013. Cassandra’s first collection, Sorrento features champagne diamonds set in the warm tones of rose gold. In fact the very first collection piece that Cassandra designed was Cognac Beauty, a ring with a centre Champagne diamond. Champagne diamonds are natural in colour and range from light beige to cognac brown. We choose from the C3 to C4 range to complement yellow and rose gold tones.
