The birthstone for April is the diamond, which shines with unparalleled brilliance, celebrated for its extraordinary luminosity and transparency. The colourless or "white" variety is the most coveted. The embodiment of clarity and strength, diamonds are the toughest gemstone known to man, deriving their name from the ancient Greek term ‘adamas,’ denoting 'invincible', making them perfect for the jewellery you wear everyday such as an engagement ring.
