Green Diamonds - The Very Highest Quality Diamonds

The first and only website which deals exclusively with the subject of Green diamonds.

Now Available

Natural fancy coloured diamonds are very rare and expensive. Green is a rare and desirable colour. The Dresden diamond, which is the largest and most famous green diamond in the world, at 40.70 carats.

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 (colourless) diamond weighed 203 carats.

Natural or Enhanced?

Natural green 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, including fancy green, 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.

The green diamonds we currently have available are enhanced or treated. If this fact puts you off owning one, then please stop to consider that every diamond has been enhanced by facetting, and most coloured gemstones are heat treated to enhance their colour. We will add a page devoted to gemstone treatments when we have more time.

How Rare?

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) green diamonds are not easy to find, so our stock selection will never be very extensive. Natural green diamonds remain so rare, that we don't bother trying to find any! Any comments we make about green diamonds will relate to treated ones unless the context clearly indicates otherwise.

How Expensive?

Quality for good quality, fancy green 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 Emeralds or Tourmaline?

Why bother to get so excited about green diamonds, when we could use emeralds, peridots or tourmalines instead? The very best emeralds are quite expensive, and they still do not have the sparkle that green diamonds possess. In addition emeralds are much less hard and durable than diamonds.

Rings

We design and create diamond rings, and we have found that many other people share our love of pink diamonds and other fancy colours. So far we have only made a small number of rings using pink diamonds, but we are busy right now with a few new ones. The problem seems to be that we sell them as fast as we can find the diamonds, and make the rings.

Pendants & Ear-Rings

We have also made a few pendants, but are yet to produce our first pair of green diamond ear-rings. Because of the variation in colours, and the small numbers of green diamonds we get to see, it is not easy to find matching pairs of green diamonds for ear-rings. Watch this space. Actually look out for new links near the top left of this page.
