The Very Highest Quality Diamonds...
Natural fancy coloured diamonds are very rare and expensive. The attempted Millennium Dome Diamond Robbery was an attempt to steal 12 large diamonds valued at a total of £200 million, an average of over £16 million each. Eleven out of the twelve diamonds were fancy coloured diamonds! The twelfth (non-champagne) diamond weighed 203 carats.
Champagne Coloured Diamonds
Champagne must be one of the most abused words when it comes to describing the colour of diamonds. We have seen many yellow or brown tinged stones described as champagne diamonds. On this site we will be featuring a number of diamonds of interesting fancy colours. We will try to give a more accurate name for each according to its colour, for example "sherry".
There are three, possibly four, possibilities for "champagne" diamonds.
Is It Natural?
Natural fancy coloured diamonds are so rare that most jewellers have never seen one, and will never own one. In recent years, methods of producing intensely coloured diamonds have been developed. We believe that the process probably recreates the conditions which existed millions of years ago to produce natural fancy coloured stones. The treatment can only work with a small minority of diamonds, and involves irradiating them causing the colour change, usually followed by heat treatment to stabilise the colour.
In our first twenty years of designing diamond rings, we had only owned 5 coloured diamonds, four of which were certificated as natural. Now that treated stones are available, we intend to make full use of their inherent beauty in our rings. Even enhanced (treated) champagne diamonds are not easy to find, so our stock selection will never be very extensive. Natural fancy champagne diamonds remain so rare, that we try hard to find any! Any comments we make about champagne diamonds could therfore relate to natural or treated ones unless the context clearly indicates otherwise.
Quality for quality, natural fancy champagne diamonds are more expensive than ordinary near-colourless ones. The processing adds to the costs, so it is generally only worth treating diamonds of high clarity. The diamonds selected for treatment usually start off a one of the less desirable colours such as brown or yellow. There is no certainty about the final colour that any particular stone will be after treatment.
What About Topaz?
Why bother to get so excited about champagne diamonds, when we could use topaz instead? The very best topaz are quite expensive, and they still do not have the sparkle that champagne diamonds possess. In addition even though topaz are very hard and durable, diamonds are many times harder and even more durable.
Pendants & Ear-Rings
We intend also to make pendants, and ear-rings. Because of the variation in colours, and the small numbers of champagne diamonds we get to see, it is not easy to find matching pairs of champagne diamonds for ear-rings. Watch this space. Actually look out for new links near the top left of this page.
