Diamonds have always been a girl’s best friend and have always had a unique place in peoples’ hearts and minds. A diamond represents a significant moment in a person’s life and it is therefore vital to ensure that the integrity of the diamond is as exceptional as the moment, commitment or love that it represents. These feminine and contemporary fine jewels bring the spirit and timeless mystic to create the enchanting treasures that have evoked strong emotions and fascinated mankind throughout the centuries. Their magic and mystery continue to burn our imagination today.

“Nothing says it better than a diamond – nature’s unique gift.”


Every diamond is immensely old, formed billions of years ago, long before dinosaurs roamed the earth. The youngest diamond is estimated to be 900 million years old. There they remained, keeping their precious secrets, until powerful forces carried them upward within volcanic molten lava, only to be concealed again by falling ash and rock.

Over millions of years, the wrath of nature in the form of winds, heat and cold would rework the landscape time and time again. They were crystallized at tremendously high temperatures and pressures, deep beneath the earth's surface. Awaiting discovery — their beauty was concealed by the very processes that made them.

Each is the result of an amazing natural journey which has turned an ancient element into the world's most sought-after jewel.

Diamonds were first recognised and mined in India at least 3000 years ago. The first significant source of diamonds were found in South Africa in 1866.

Southern Africa still produces the majority of the world's diamonds, particularly Botswana. There is also diamond production in Russia, Canada, USA, India, China, South America & Australia.

“Truly, a diamond is a miracle of nature.”


Diamonds which have been prepared as gemstones are sold on diamond exchanges called bourses. There are 26 registered bourses in the world. Bourses are the final tightly controlled step in the diamond supply chain. Wholesalers and even retailers are able to buy small lots of diamonds at bourses, after which they are prepared for final sale to the consumer.

The image of diamonds as a valuable commodity has been preserved through clever marketing campaigns, in particular the De Beers diamond advertising campaign which has been acknowledged as one of the most successful and innovative campaigns in history. It is best captured by the slogan "a diamond is forever".

Another example of successful diamond marketing, after the development of the Argyle diamond mine in Australia in 1986 is the Australian brown or Cognac diamond. Cognac diamonds have now become sought after gems.

The 4 C’s

Gemmologists and jewellers access the physical attributes of diamonds using the 4 C's classification system — cut, carat, colour and clarity, although a diamonds beauty is based on far more than just these characteristics. While most diamond's qualities are defined by nature, it takes a master craftsman to unlock the diamond's true brilliance, fire and beauty.


Clarity refers to the presence of inclusions in a diamond. These are naturally occurring special fingerprints within the stone and are identifying characteristics such as minerals occurring while the diamond was being formed within the earth. The majority of these natural birthmarks are invisible to the naked eye, yet they affect the way the light is reflected and refracted within the stone, even with a loupe. It is only when a diamond clarity is graded "I/P II it is possible to see the birthmarks with the naked eye. There are very few flawless diamonds found in nature, making these diamonds much more valuable.


Colour refers to the degree to which a diamond is colourless. They are graded on a colour scale which ranges from "D" (colourless) to "Z". Nature has created diamonds in shades of blue, green, pink, yellow, red and orange. These diamonds are called "coloured fancies" and are extremely rare and highly treasured.


Carat refers to the weight of a diamond and is often mistaken for size. Since large diamonds are found less frequently, a single 1 carat diamond will be more valuable than 2 half carat diamonds assuming, colour, cut and clarity are the same. A diamond's setting should always optimise its beauty.


Cut refers not only to the angles and proportions of a diamond, but is the only one of the 4 C’s that is influenced by the human hand. Diamond cutting requires great skill and the cutter must polish tiny surfaces known as facets onto the rough diamond. To cut a diamond perfectly, a craftsman will often need to cut away 50% of the rough diamond. Cut also refers to round, square, heart, pear. Regardless of the size, shape or colour of the diamond, once lit, the fire of inspiration burns forever.

Eternal Celebration
