MADE FOR YOU

Our Diamonds

For decades, diamonds have become a symbol of enduring love and everlasting commitment. Today they continue to remain highly prized for their unique beauty, resilience, and timeless nature.
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.

FROM RAW

Mined Diamonds

Often taking billions of years to form, natural mined diamonds occur when carbon atoms, resting deep beneath the Earth’s surface, are subject to high temperature and intense levels of pressure.
Diamonds are the hardest natural mineral substance, rating a ten on the Mohs scale of hardness. This makes them the perfect choice for a piece for a jewellery which is destined to be worn for a lifetime.
Every diamond is structurally unique and beautiful in its own right. A diamonds value is determined by four key factors: colour, cut, clarity, carat. Balancing the quality of these four factors will help to ensure you fall in love with the perfect diamond for you, one which will compliment both your personal style and budget.

Lab Grown Diamonds

Lab Grown Diamonds (sometimes alternatively known as Lab Created Diamonds, Man Made Diamonds, Engineered Diamonds and Cultured Diamonds) are grown in controlled laboratory environments using advance technological processes. These processes mimic, and accelerate, the conditions under which mined diamonds naturally develop within the Earth’s crust.
Lab Grown Diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure.
They are made from the same material as natural mined diamonds and exhibit the exact same optical and chemical properties.
Simply put, Lab Grown Diamonds are real diamonds. The only difference is their origin.

SOMETHING UNIQUE

Pink Diamonds

The highly prestigious pink diamond is desired by master jewellers and wearers alike.
Unlike white diamonds, which are prized for their lack of colour, fancy-coloured diamonds are graded according to the intensity of their colour.
As a general rule, coloured diamonds tend to have more inclusions than colourless diamonds. Therefore, you will find it is extremely rare to view a near flawless pink diamond. Their value is determined instead by three factors including hue, tone and saturation.
As the Argyle Pink Diamond mine has come to the end of its life, the opportunity to own a Pink Diamond is now rarer than ever before – making it one of the most valuable pieces in any collection.
