Diamond is the hardest known natural material on earth. This highly sought-after gemstone is typically about 99.95% carbon, and forms in a cubic crystal system. Diamonds are formed under high temperature and high pressure conditions deep under the Earth’s surface, before being transported to the surface through volcanic activity.
Diamonds have been recognized for their exceptional hardness for thousands of years. The name diamond references its hardness, derived from the Greek word ‘adamas’ for unconquerable. Diamonds are a 10 on the Mohs scale of hardness, and therefore can only be scratched by another diamond.
As well as their inherent hardness, diamonds have an unrivalled lustre, meaning that they can hold and retain a polish far longer than other gemstones. This is one of the many reasons people opt for diamonds in engagement rings. Diamonds also have a brilliance and fire to them that is completely unique and highly attractive. Diamonds are cut in such a way to maximise these captivating optical effects.
Diamonds primarily occur as colourless to yellow. However, owing to trace elements, inclusions, and growth conditions, they can form in a range of colours, including red, pink, orange, yellow, blue, green, brown and black. The majority of diamonds are on a scale from colourless to yellow, owing to traces of nitrogen within the crystal structure.
Diamonds have always been noted for their outstanding combination of physical and optical properties. The Greeks believed that diamonds were the tears of the gods. Diamond is the birthstone for April, and is gifted for 60th wedding anniversaries. However, we firmly believe that you don’t need a reason to add the sparkle of a diamond to your jewellery collection.
