Diamond

Diamond a “Girl’s best friend”, and according to the popular marketing campaign of De Beers, “Diamonds are forever”. The world’s most well-known and valuable gem, the record was last set in 2017, when the “Pink Star” sold for over $71m. Diamond is the birthstone for April and used as the anniversary gemstone for the 10th and 60th years.

The name Diamond comes from Greek “adamas” meaning invincible, alluding to the fact that Diamond is the hardest natural substance known on earth. This feature of Diamonds has long been known, for thousands of years it has been believed that Diamonds can protect the wearer from harm, making them invincible in battle, and even cure someone from poisoning. Interestingly it was sometimes believed that the powers of the Diamond were not effective if purchased only if given as a gift, what better sentiment than to give as a gift something not only beautiful but to keep your loved one safe.

Commonly we think of Diamonds as being colourless or what we define as the “colourless Diamonds”, where they can range from no colour at all to pale tints of yellow or brown. In fact, Diamond occurs in all the colours of the rainbow as well as white and black, with these deeper tints being described as fancy colour Diamonds, and as can be seen in the case of the Pink Star some of the most valuable gems in the world. The rarest of all Diamonds are true red Diamonds, with only a few known in nature.

Diamonds used in jewellery can vary widely in quality, and therefore in price. Diamonds are assessed mainly on 4 characteristics: colour; the absence of colour in colourless Diamonds or the depth and attractiveness of colour in fancy colour Diamonds, clarity; how many and how visible are any features that can be seen on or in the stone, carat; quite simply a unit of weight, one carat is equal to one fifth of a gram, and whilst there is some relation between weight and size it should not be confused, finally cut; this is not only the shape of the Diamond but how well proportioned it is in order that it interacts with light in the most beautiful way. There are many other factors that a skilled Diamond expert will look for in a stone, which is why it is important to choose a Diamond from a reputable supplier who employs experienced and qualified staff, as they can help you choose the perfect Diamond for your jewellery and budget.

Diamond gets more valuable when any quality factor is increased, larger Diamonds are rare and so command high prices. Smaller Diamonds are very effective when used together in jewellery to create a larger piece with lots of sparkle without the large price tag of bigger individual stones, or when used as accents for coloured gemstones. Diamond is the ideal gemstone to use in jewellery, it is rare, it is beautiful, it is durable, and it is desirable. It is durable enough to be worn every day, and with care can last more than a lifetime. Whilst it is the hardest natural substance, it is very difficult to scratch, Diamonds are not indestructible as the name implies, they are able to be chipped or even broken with a sharp knock or blow, so care should be taken that this cannot happen. They should be stored so they cannot be scratched by or scratch other items and cleaned with warm water with a little gentle detergent or soap.

Diamonds can be treated to alter the colour or improve the clarity. They can be coated, irradiated and heated to alter the colour, and they can be drilled or filled with glass to improve the clarity. Some of these treatments are stable and durable, and some are not, but all treatments to Diamonds must be disclosed. We generally do not sell treated Diamonds, almost all our products are natural Diamonds, occasionally we may use fancy colour Diamonds that have been treated to create an attractive colour, but we will always let you know of any treatment that you should be aware of.
