April birthstone: Diamond

Classic white

The most popular diamonds are white and colourless. The April birthstone is traditionally this type of diamond. However, they come in a range of colours including green, yellow, blue, purple, pink and red. The colour depends upon the type of impurities present in the stone. For instance, yellow ones have minuscule traces of nitrogen. Blue ones contain boron. 

The invincible

Diamond is among the hardest substances on the globe. Its name comes from the Greek word “adamas”, which means “invincible” or “unbreakable”. It is the preferred gemstone for many rings, necklaces, earrings and bracelets, because of its toughness. It ranks 10 on the Mohs scale of hardness.

Love and lore

The April birthstone signifies eternal love, clarity, strength, and everlasting affection. No wonder it’s a staple in engagement rings and wedding jewellery! During the middle ages, diamonds were thought to hold healing powers as well.

Our love for diamonds started in India, where gems were gathered from rivers and streams. They were traded as early as the fourth century BC, coveted by royalty and the wealthy. Later, Indian diamonds were taken to medieval markets in Venice. By the 1400s, diamonds were fashionable accessories for Europe’s elite.

Archduke Maximillian of Austria gave the first recorded diamond engagement ring to his betrothed, Mary of Burgundy, in 1477.

Location, location, location

Diamonds are made of pure carbon and form over billions of years.

India’s diamond supplies began to decline in the early 1700s and Brazil emerged as a source, dominating the diamond market for more than 150 years.

The discovery of diamonds in South Africa in the late 1860s marked the beginning of the modern diamond market. De Beers Consolidated Mines Limited was established in 1888, and by 1900 De Beers controlled an estimated 90 per cent of the world’s production of rough diamonds.

Now, that’s a rock!

One crown in the British Crown Jewels collection contains 2,868 diamonds! It includes the famous cushion cut, 317.4 carat Cullinan II diamond, cut from the world’s largest diamond. The sceptre, sovereign ring and orb also contain multiple diamonds.

Hayley Baldwin, Megan Fox, Pippa Middleton and Lady Gaga are just a few famous recipients of diamond engagement rings.

Care and cleaning

Diamond is usually durable enough to be placed in an ultrasonic cleaner. However, if your diamond has many inclusions or has been treated, clean it with a lint-free cloth, or use warm water, mild soap and a soft toothbrush. It’s also a good idea to have your diamond periodically cleaned and its setting examined by a professional jeweller to maintain its beauty and integrity over time.
