A DIAMOND'S JOURNEY

The phenomenal, precious and naturally beautiful gems we've come to know as diamonds actually began their journey long, long ago. Forged for millions of years under pressure fifty thousand times normal atmosphere and in temperatures up to 1,300ºC/2400ºF, these crystals have traveled through the sands of time from the earth's depths to bestow their beauty and mystique on the human race.

This remarkable feat of endurance that took millions of years to emerge requires the equally daunting efforts of explorers, geologists, physicists, engineers, chemists and biochemists and scores of technicians and labourers, equipped with the latest analytical equipment, tools and tests—to bring them to the cutting table.

As the strongest naturally forming substance known to man, first discovered over 2000 years ago, these stones we know of as diamonds are of a very small fraction of crystals that have made their way to the earth's crust through volcanic activity—and of these very few that made the journey to the surface—even fewer of these will actually be of the quality to make their way into fine jewellery.

At Premier Diamond Alliance we guarantee the diamond’s journey is availed with dedication, passion and expertise bringing only the finest specimens of this odyssey to the diamond and jewelry customer.
