The Fascination With Fancy-Coloured Diamonds
In this final guide, we are going to explore even more fancy-coloured diamonds to unlock their unique stories and why they are so popular among consumers.
In our previous guides, we featured some of the rarest diamonds on earth in the form of Red, Blue and Green diamonds. The stories behind their colour can sometimes baffle science which shows how we are still learning the nature of their being.
Colour, tone and saturation are still the guiding principles used to determine their exact nature.
In this guide, we are going to explore:
- Orange diamonds.
- Chameleon diamonds.
- Pink diamonds.
- Purple diamonds.
According to some statistics, you have a better chance of finding a fancy-coloured diamond than winning an Oscar!
When a diamond is saturated with nitrogen, it can cause the diamond to develop an orange colour. It's true that nitrogen is the source of yellow hues as well. The difference is the way the nitrogen atoms group together when the diamond forms.
A hyper-specific grouping will absorb blue and yellow to create an orange colour.
Due to the majority of orange diamonds found containing a secondary colour, finding a pure one is extremely difficult.
Trivia - Orange diamonds are scaled from faint to fancy deep.
If you're thinking of the animal then you have the right idea. Chameleon diamonds are a scientific marvel because they can change colour! They have two types - classic and reverse.
Trivia - chameleon diamonds are only found in fancy, fancy dark or fancy deep.
Classic - Most chameleon diamonds fall under this bracket. In this instant, they turn from an olive green colour to a mixture of grey, yellow and green and then to an orangey yellow colour.
Trivia - This can last from a few minutes to an hour! One of the contributing factors is heat.
Reverse - These stone show contrasting behaviour. A light yellow stone can become darker or green in a dark environment.
Furthermore, chameleon diamonds can respond to an ultra-violet light which results in a colour combination of at least two of these colours: yellow, grey, brown and green.
These stones are some of the rarest in the world and currently holds the accolade of being The Most Expensive Diamond Bought in Auction.
Despite the fact they can be found in several places around the world, the largest known deposit lies in Western Australia.
How Pink diamonds get their colour is still unknown but they are graded from faint to dark.
Pink diamonds can be found with a secondary colour but the price that costs will depend on how rare that secondary colour is.
Another scientific marvel because the origin of their colour is unknown! However, traces of hydrogen and boron can be found in the purple stone.
NOTE: If you do want to purchase a purple fancy-coloured diamond then ensure they have not been colour treated.
When a diamond is treated, they are subject to extreme pressure and temperature which changes their colour. Due to this being an artificial process, they should cost less than natural stones.
The colour scale for a natural stone is faint to fancy dark.
It's not uncommon for a purple diamond to contain a secondary colour, the most common of these are pink, red, brown and grey.
Fancy-coloured diamonds are incredible stories.
Even though we do not fully understand them yet, the instant feeling we get from viewing one provides our own unique experience.
