OUR DIAMONDS
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 yours.



FANCY COLOURED DIAMONDS
Fancy coloured diamonds have been part of the Cassandra Mamone story since the very beginning. When Cassandra launched her debut collection, Sorrento, in 2013, she chose champagne diamonds set in roseĀ gold - a pairing that felt instinctive,Ā and has defined the brand's aesthetic ever since.
Today, we source the full spectrum of fancy coloured diamonds. Whether you're drawn to the warm golden tones of a champagne or cognac diamond, the sunshine brilliance of a yellow diamond, or any other colour that speaks to you, we can source it.
What Is a Fancy Coloured Diamond?
Fancy coloured diamonds are naturally occurring stones whose colour forms over billions of years deep within the earth. Champagne and cognac diamonds get their warm honey-to-brown tones from nitrogen during formation. Yellow diamonds - one of the most sought-after fancy colours - owe their vivid glow to the same element in higher concentrations. Pinks, blues, and greens are rarer still, each the result of unique geological conditions.
Unlike white diamonds, which are graded on the absence of colour, fancy diamonds are prizedĀ forĀ their colour. The depth and warmth of the stone is the feature, not a flaw - and it's what makes each one wholly individual.
Why Choose a Fancy Coloured Diamond?
Fancy coloured diamonds offer something a white diamond simply cannot: personality. No two stones share the same tone, depth, or quality of light. When you choose a fancy diamond for a bespoke piece, you're not choosing a category - you're choosing that specific stone, with all its singular character.
They can also offer exceptional value. Many fancy colours are more accessible in price than white diamonds of comparable carat weight, making them a beautiful option for clients who want something distinctive without compromise.
