Diamond: The Bright & Precious April Birthstone

Historical Origins and Symbolism of Diamonds

The origins of diamonds can be traced back billions of years, and they are natural crystals formed under extremely high pressures and temperatures deep within the earth. These gems were eventually brought near the surface through geological activity such as volcanic eruptions, allowing humans to mine and appreciate them. Diamonds are currently produced in more than 30 countries around the world, with the top five producing countries being Australia, the Democratic Republic of the Congo, Botswana, Russia, and South Africa, which account for about 90 per cent of the world's diamond production. Diamonds are produced in scarce quantities and are usually colourless crystals that reflect a colourful lustre. As a type of diamond, diamond is the hardest natural substance known in the world, symbolising endurance, eternity, purity, chastity and innocence.


Symbolically, the name diamond derives from the ancient Greek word "adámas", meaning unconquerable or indestructible, which is in keeping with the diamond's character as the hardest natural substance on earth. Considered a symbol of strength, courage and indomitability because of their indestructibility, diamonds began the tradition of being used as engagement stones in the 15th century when Maximilian of Austria proposed to Mary of Burgundy with a diamond ring, and their clarity and brilliance have been imbued with the symbolism of purity and unchanging love, which has led to diamonds being used in engagement rings and wedding jewellery as a symbol of everlasting commitment.


In addition, diamonds also symbolise luxury, status and achievement, and are often used as a sign of personal achievement and high social status. From ancient civilisations to the Middle Ages and into modern times, diamonds have always been regarded as precious stones and have never lost their charm. During the Middle Ages, natural diamonds became a status symbol and were sought after by European royalty, and crowns throughout the continent were inlaid with diamonds. One of the most famous diamonds is the Koh-i-Noor. An Indian diamond mined centuries ago, it has passed through the hands of many monarchs and rulers - from Persia to Afghanistan - before finally arriving in England as part of the British Crown Jewels.


Types of Diamonds and Grading

Types of diamonds are distinguished primarily by their colour, and although most diamonds appear colourless or nearly colourless, they can also appear in a variety of colours, including yellow, brown, blue, green, pink and even red. The appearance of these colours is usually due to impurities in the diamond's structure or specific types of crystal defects. For example, yellow diamonds owe their colour to the presence of nitrogen, while blue diamonds owe their colour to the presence of boron.

Diamonds are graded according to the so-called "4C" criteria:

  • Cut

This refers to the shape of the diamond and the cutting process, which not only affects the shape of the diamond, but also its fire, brilliance and sparkle. A great cut means that the diamond is shaped, symmetrical and polished to the highest standard, capturing and reflecting the maximum amount of light and giving the diamond more sparkle.

  • Clarity

Clarity ratings are based on the degree of imperfections within and on the surface of the diamond. These flaws can be inclusions (internal flaws) or scratches and wear (surface flaws). Clarity grades range from Flawless (FL) to Imperfect (I).

  • Colour

Diamonds are graded on a colour scale ranging from D (completely colourless) to Z (visibly coloured). D-grade diamonds are considered the most precious and rare as they are completely colourless.

  • Carat Weight

The carat is the unit of measurement of a diamond's weight, with 1 carat equaling 0.2 grams. Diamonds with higher weights are usually worth more. An increase in weight results in a proportional increase in the price of the diamond, especially when a specific carat weight standard is reached (e.g., 1 carat, 1.5 carats, 2 carats, etc.), but its value is also affected by the other three Cs.


The final valuation of a diamond relies on a combination of these four factors. The overall value of a diamond depends not only on its carat weight, but is also influenced by its cut quality, clarity and colour. Ideally, finding a balance means choosing a diamond with a satisfactory cut, clarity, colour and carat weight without going over budget.

Care and Cleaning of Diamonds

At 10 on the Mohs hardness scale, diamonds are the hardest natural gemstone known to man, which means that they are highly resistant to wear and scratching, making them an excellent choice for all types of jewellery. However, diamonds do require careful care, and if they are not handled correctly during their use, they may become worn.

  • Proper Storage

When not being worn, diamonds should be stored separately in a jewellery box with soft fabric or wrapped in a soft cloth to prevent them from bumping into each other and other stones or metals and to avoid scratches.

  • Professional Inspection

Have your diamond and setting inspected by a jewellery expert on a regular basis (e.g. once a year) to ensure that the setting is secure, to prevent the diamond from falling out and to ensure that the stone is in good condition.

  • Avoid Chemicals

Remove diamond jewellery when handling chemicals (e.g. detergents, perfumes, hairsprays, etc.) to prevent chemicals from damaging the diamonds or metal settings.

  • Clean Regularly

Diamonds are susceptible to dust, dirt, natural skin oils, lotions, etc., which can dull them. To maintain the brilliance of your diamond, it is recommended that you opt for professional cleaning. If you need to clean at home, gently scrub your diamond with a soft brush and mild soapy water. After cleaning, rinse with water and gently wipe dry with a soft, fibre-free cloth.
