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.
Orange– Not as rare as other coloured diamonds, they contain strong yellow or brown modifiers giving them their beautiful natural appearance. Like the pink diamond, these are also found in the Argyle mine in Western Australia. the most intense the colour, the higher the price approximately $15,000 – $50,000 USD per carat.
Yellow – This diamond is the most popular of the colour diamonds and are also known as ‘canary diamonds’ due to the purity and clarity of the diamond. The price for 1 carat of good quality diamond ranges between $5,000 – $30,000 USD
Green – The natural green diamond are so rare that most jewellers wont see one in their career. The Dresden diamond is the most famous and largest green diamond in the world at 40.70 carats found in India. Only a handful of green diamonds are sold into the market making them the most sought as they contain a yellowish, bluish or greyish modifying colour. Prices range from $16,000 + USD
Blue – The blue diamond can command more than pink diamonds, due to them being extremely sought out and the natural colour making them so rare. The colour of these diamonds can range from light blue to deep blue. They range between $60,000-$170,000 UDS.
Purple – This is my favourite colour diamond in the range. These beautiful diamonds contain pure colours that cause that intenseness in the diamond. The purple diamond is referred to many different names such as Plum diamonds, Orchid diamonds, Lilac diamonds, Mauve diamonds, Lavender diamonds and Grape diamonds. The ‘Purple Orchid’ diamond at 3.37 carat has an asking price of $4 million UDS.
Black – A favourite with collectors of precious gemstones, this beautiful diamond was regarded as too difficult to cut and polish by many jewellers due to the many lumps of carbons in the diamond. The starting price per carat can cost between $1,500 -$3000.
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.
