Buying fancy coloured diamonds is a very different process to buying a regular white diamond. The major factors of cut and clarity for white diamonds are of much less importance when choosing a fancy coloured diamond and the choices available in the coloured diamond market are much more restricted. Rather than size being the greatest factor determining the price the purity and vibrance of the diamond’s colour is the primary concern. Like any coloured gem the more attractive the colour produced by the diamond the more saleable the stone and the greater it is worth. As the availability of vibrant pure coloured diamonds is so acutely rare, the demand for these diamonds is extremely high and this is why they command such high prices. There are many more diamonds that are still very beautiful but just not quite as pure in colour and although still very expensive are a little more readily available and affordable. Choosing which colour diamond you would like is always the first decision and then just how big and bright the diamond will be will be determined by you budget.
Guide to establishing a budget for buying coloured diamonds
As coloured diamonds have become more well known many people are adding them to their engagement rings and diamond dress rings. Unfortunately most people are often unaware of just how expensive some colour varieties can get even when they are quite small. Therefore it is always best to do a little research into the price of each of the colours and establish a general budget to establish what size and quality you can afford. Once the budget has been set you really must be quite flexible as to the shape, weight and vibrance of the colour of the diamond you are wanting to achieve.
Guide to colour quality selection for fancy diamonds
Coloured diamonds are primarily cut to best enhance the depth and distribution of the diamond’s colour. The quality grade of the cut of the diamond is not of major importance in coloured diamonds as they are often cut deeper and less conventional than a white diamond would regularly be cut. It is still preferable to have a very good symmetry but the scintillation will always take a backwards step to improving the vibrance of the colour. Coloured diamonds are also more often cut in the fancy shaped diamonds as they lend themselves to achieving a greater depth than a traditional round brilliant design. Some of the most common shapes for coloured diamonds are the radiant cut and the cushion cut designs.
Clarity is also considered much less important in coloured diamonds. This is because in white diamonds there are many good diamonds with large inclusions and far less without, making the rarity of flawless diamonds the reason for their increased price. Vivid fancy coloured diamonds are so much rarer than any flawless white diamond that it’s actual clarity really does not add to it’s price except where the inclusions become visible to the naked eye.
Of the colour varieties yellow, fancy browns (like champagne) and black diamonds are relatively inexpensive and are within an affordable price range. All of the other colours, pink, blue, green, orange, ect are really only for the elite diamond customer with even very small diamonds being very expensive.
Natural coloured diamonds
Natural Fancy coloured diamonds are extremely rare and because of this and the ever increasing demand for coloured diamonds the price fetched for the rarest colours can be well above that of regular white diamonds. Those diamonds that demand the most money are pink, blue, red, orange and green with even small sizes being worth thousands of dollars.
Fancy yellow diamonds are however a lot more readily available and are a lot closer to the price of white diamonds. Unlike many other natural coloured gems, certified natural coloured diamonds are not treated to enhance their colour in any way ensuring that the colour will never fade or change. This is why there is also a great variance in the strength and hue of each natural diamond and the price for each diamond is judged on its individual beauty.
The purest coloured diamonds of high saturation are the most expensive and often sell very quickly, most of the coloured diamonds available, although still very expensive are not perfect with many being either lightly coloured or including grey, brown and yellow in the mix of colour. This is the unfortunate aspect of buying a natural coloured diamond that people’s expectations of the coloured diamond they would like, is in many cases well above the price the customer is willing to spend and the less favourable colours are their only option.
