LOOSE DIAMONDS
The hardest material found on earth.

ABOUT DIAMOND
Diamond forms under high temperature and pressure conditions that exist only about 100 miles beneath the earth’s surface. Diamond’s carbon atoms are bonded in essentially the same way in all directions. Another mineral, graphite, also contains only carbon, but its formation process and crystal structure are very different. Graphite is so soft that you can write with it, while diamond is so hard that you can only scratch it with another diamond.
58X HARDER
Diamonds are the hardest material on earth: 58 times harder than anything else in nature.
South Africa is one of the world’s largest producers of diamonds.
Platinum Jewellers’ Owners are 3rd generation of diamond merchants trading since 1961, and are a leading retailer of locally sourced and conflict-free diamonds.

FANCY COLOUR DIAMONDS
Dazzling brilliance. Captivating color.

The planet’s most valued gems are fancy color diamonds. Diamonds in the normal color range are colorless through light yellow and are described using the industry’s D-to-Z color-grading scale.
Fancy color diamonds, on the other hand, are yellow and brown diamonds that exhibit color beyond the Z range, or diamonds that exhibit any other color face-up.
These rare specimens come in every color of the spectrum, including, most importantly, blue, green, pink, and red.
