What’s Your Flavour?

Part 2:

Whilst in a recent discussion, one of my work colleagues informed me that in his previous job, he sold diamonds. Along with selling  traditional clear stones,  he also sold coloured stones.

I was quite excited to find out the process of purchasing these coloured stones which are unique and  rare. Diamonds occur in almost every colours, containing impurities or structural defects that cause  discolouration. Pure diamonds are perfectly transparent and colourless. They are the most popular and are used in the majority of engagement rings.

Red– This is the most rarest and most expensive diamonds. The starting price for a .20ct is $100,000.00USD. These beautiful  diamonds contain pure carbon. Just like colourless diamonds, they have a different appearance when placed  in various lighting environments that gives its uniqueness.

Pink – This is also a rare diamond as the higher the  intensity the most expensive they are. Many of these pink diamonds are found in the Arglye mine situated in Western Australia. Many scientist still don’t know how they get their colour, as there are no traces of elements that are found in other coloured diamonds. The most expensive pink diamond was sold in 2010 for over $46 million USD weighing at 24.78 carat.

Colourless – The most popular of all diamonds, these beautiful gems look amazing when mixed with other coloured diamonds. Remember the 4 c’s when choosing the perfect diamond. Price’s range from $2,000 + depending on the clarity of the diamond.

Most people purchase their diamonds already set, however they are also purchased loose. It is recommended that prior to purchasing any diamond, get it evaluated. The evaluation shows the inclusions of the diamond which provide the uniqueness for that stone, making it identifiable. This is a must if you are purchasing a coloured stone.

When my brother-in-law was purchasing an engagement ring for my sister, he purchased the diamond loose. Once he found the diamond that met his criteria (based on the 4C’s) he got 2 evaluations to verify the stone. Once he got the diamond set, he then viewed the diamond again based on the evaluation to ensure that it was the diamond he chose.

 Looking at the array of colours and the rarity of the stones that are available, I have to agree that diamonds are definitely a girl’s best friend.
