Gemstone: Diamonds – a Girls Best Friend

Why are diamonds a girl’s best friend? Diamonds, the most popular gemstone, are also the symbol for steadfast love.


As it’s April and Diamonds are the birthstone for April I thought I’d do a bit more research into the famous stone and share it with you all. Hopefully you’ll find some of the facts as intriguing as I did! …… keep reading to discover a little more about the precious diamond.



The name “Diamond” is derived from the Greek word ‘adamas’ that means proper, unalterable, unbreakable, untamed.

  • In their pure state, diamonds are colourless, these are the diamonds we all associate with and recognise as the traditional engagement ring.
  • Blue and red are the rarest coloured diamonds. These are often mistaken to the general public as other gemstones..… but look closely next time you’re passing a jewellers window, you’ll see that sparkle!
  • Yellow and brown are the most common coloured diamonds.

In the United Kingdom, diamond was a well known symbol for the 75th anniversary, but this changed to the now more common 60th anniversary after Queen Victoria’s 60 years on the throne was widely marked as her Diamond Jubilee.

The diamond as the April gemstone has captured the hearts of many and is the most coveted crystal to date. Deemed as the King of all birthstones, diamonds make the ideal choice for an April birthday gift. She’ll love you for it!



Diamonds are thought to have been first recognised and mined in India, where significant alluvial deposits of the stone could be found many centuries ago along the rivers Penner, Krishna and Godavari.

Check out the map below to see where Diamonds are sourced today:



Diamond is the hardest known natural material on the Mohs scale (Unit of measurement used to test the hardness of gemstones.)  Hardness is defined as resistance to scratching and is graded between 1 (softest) and 10 (hardest). Diamond has a hardness of 10 on this scale and is four times harder than the mineral corundum, which is 9 on the Mohs scale. So, even though might be able to scratch some diamonds with other materials, the hardest diamonds can only be scratched by other diamonds and nanocrystalline diamond aggregates. Although I wouldn’t recommend trying this on your precious engagement ring!


Here’s a few facts about “Carats” and what it all means…..

  • The word carat comes from the Carob Mediterranean tree whose seed was used for centuries as the standard of weighing precious stones.
  • Only one polished diamond out of a thousand weighs more than one carat. (so if your jewellery is one carat, I would count yourself one lucky lady!)
  • 1 carat = 0.2 grams or .007 ounces.
  • The largest rough diamond, discovered in 1905, is the Cullinan diamond, weighing in at 3,106 carats (Nearly 1.3kgs!)… that would be some bling and a half!
  • A single diamond of two carats is worth more than twice a much as 2 one carat diamonds.

The round cut diamond is the most popular diamond shape, representing approximately 75% of all diamonds sold whereas the princess cut diamond, first created in 1980, is the most popular fancy diamond shape, especially for engagement rings. The oval diamond is also a popular choice as is a modified brilliant-cut. Both round and oval cut diamonds possess a similar fire and brilliance.


The ancient Romans and Greeks believed that diamonds were tears cried by the gods or splinters from falling stars, and Romans believed that Cupid’s arrows were tipped with diamonds. (perhaps the earliest association between diamonds and romantic love… ohhh la la)

Can you believe this? Scientists have discovered a planet that they believe is composed mostly of carbon, and is one-third pure diamond! Discovered in 2004, the planet orbits a nearby star in the Milky Way, and is named “55 Cancrie”.

Perhaps even more amazing….. scientists have discovered a star that is essentially a diamond of ten billion trillion trillion carats.  They named the star Lucy after the Beatles song “Lucy in the Sky with Diamonds.(take a listen!)

Did you know that 80% of the world’s diamonds are not suitable for jewellery.

The largest diamond ever found was the Cullinan at 3106 carats. To produce a single one-carat diamond, 250 tons of earth will be mined.
