Our Diamonds


Natural diamonds are made of highly organised carbon atoms and are formed over billions of years deep beneath the Earth's surface. Over the years, diamonds have become a symbol of love and commitment, and valued for their complexity, beauty and timelessness.

Diamonds are the hardest natural mineral substance. They are rated a ten on the Mohs scale of hardness, making them a perfect choice for a piece that is made to be worn for a lifetime.

Every diamond is beautiful in its own right, however there are four key factors that primarily determine its value: colour, cut, clarity, carat. At LOUISE JEAN, we offer a wide variety of diamond options to suit a range of budgets and preferences. We recommend balancing the quality of all elements within your specified budget.


LOUISE JEAN is committed to providing our customers with high-quality, timeless jewellery without compromising our brand values.

Louise personally sources our diamonds and stones through a network of trusted Australian and global suppliers. Traceability and responsibility are integral to our operations, and these values are the backbone to our social and environmental standards when sourcing the diamonds for our pieces.


We work exclusively with respected and trusted suppliers who are in compliance with the requirements of the System of Warranties, from the mine, to cutting, to market. They are sold on the guarantee that the diamonds originate from legitimate sources and are strictly in compliance with the laws and resolutions set in place by the United Nations.


Lab-grown diamonds offer a sustainable alternative to naturally mined diamonds as they are created under highly controlled laboratory conditions that replicate the Earth's natural growth process of crystallising carbon. The terms lab-grown, man-made, or cultured diamond, are used interchangeably across the jewellery industry and are simply used to describe the scientific process involved in creating a diamond 'above-ground'.

Lab-grown diamonds are chemically, optically, and physically identical to natural diamonds and exhibit the same visual properties of fire, scintillation, and sparkle. This means each individual diamond crystal will have variation in appearance and grading, just like diamonds formed naturally. Much like a natural diamond, the value is primarily determined by the carat weight and quality grading, however you can expect a considerable price difference between the two.
