Diamonds usually are naturally available in a very broad selection of colours. Most people know about translucent diamonds and GIA’s colouring grading system that is used to categorise a diamond’s body colour… you recognize D, E, F, and so forth This colour grading technique is only used to classify the commonest diamond body colour of orange however anytime a stone is found in another colour including pink, blue, green, and so forth; then this diamond is referred to as any “fancy diamond”.
Natural Extravagant diamonds can be very expensive and lots of times more expensive than a related size colourless diamond. An amazing example of a Fancy diamond will is the infamous 45. 52 karat fancy deep blue diamonds, the Hope Diamond, which can be on display in the Smithsonian Natural History Museum in Washington, DC.
A shade-enhanced diamond is a fully natural diamond that has got its colour changed. And also best of all, color-enhanced expensive diamonds come in a very wide selection of colours at very affordable prices!
Some history-
For many, many years it is well known that a diamond’s shade could be “improved” by locating a bit of coloured substance on top of a diamond and just as promised… a diamond that got a noticeable yellowish colour would certainly change to a more attractive in close proximity to a colourless diamond. Unfortunately, this colour-enhanced diamond may change back to its unique body colour if this coloured ingredient was unintentionally removed.
In much more recent years, the technology connected with colour-enhanced diamonds adjusted extremely high-tech. It is now likely to completely change the colour of a new diamond! These processes are viewed as permanent because it does keep on being stable when exposed to day-to-day normal conditions. The colour probably fades if exposed to natural light or is washed away by harsh chemicals.
How will it be done?
The desired outcome of all of these treatments is to have a considerably more marketable diamond. A significantly less marketable diamond would be a stone that has a low body colour or perhaps sometimes a lower clarity. Area enhanced diamond treatment organizations know if they start off using a certain type of diamond and also process it for a certain quantity of time that they should end up having a certain color but it would not always work that way. It is a science that does demand some art in its functions… the only process that gives steady results is the coating method.
The three processes are seen as follows-
Process #1- HPHT Color Enhanced Diamonds- Highly pressured / High Temperature (HPHT) treatment method can improve the colour of a number of types of brown diamonds, therefore, increasing their value. Typical Electric has developed a process this pretty much is mechanical feinted of a diamond’s creation with nature. The colour-enhanced stone will be heated up to an extremely high temperature under a very high, sits firmly pressure. Faults in the very structure are then rearranged resulting in an alteration of the diamond’s colour.
Because the conditions involving HPHT are very similar to the diamond’s original formation, only a effectively equipped lab will be able to absolutely identify this type of color superior diamond. HPHT was first employed to turn yellowish diamonds straight into more marketable fancy hued enhanced diamonds, but now it is additionally used to transform some unpopular brownish diamonds into far more desirable colorless colored superior diamonds.
Process #2- Irradiated Color Enhanced Diamonds- FINE… do not start getting most excited because you saw your message irradiated! This is a 100% harmless process that is very similar to what on earth is used to preserve food by simply exposing it to a steady flow of Gamma rays. The colour-enhanced diamond process is completed in several different ways but the answers are all the same. You start with a lower colour (P, Q, Ur, etc . ) 100% organic diamond that has already been reduced and polished, then it really is exposed to a stream associated with fast electrons.
During this section of the process the diamond will certainly turn to a very dark colour because some of the atoms within the diamond’s crystal structure have recently been dislocated and this consequently has affected the way lighting passes through the diamond. Following the diamond goes through the controlled heating (annealing) procedure, this allows some of those atoms in order to relocate (partially repaired) to be able to obtain the desired colour.
Procedure #3- Coated Color Improved Diamonds- The coating of polished diamonds refers to a skinny artificial layer that adjusts the colour of the diamond. Typically the coating can either be of the specified colour or can cause a coloured interference-effect. Unfortunately, sometimes this procedure is done to deceive some sort of buyer.
It is a relatively easy course of action to perform, it has been around for quite a while (although the coatings elements are much better now), plus it does not require a lot of high-priced high-tech equipment. Recently, We’ve seen some pink sprayed diamonds on the market, they are incredibly appealing…. and of course you would have to order them knowing that they have been sprayed and follow your jeweler’s guidelines about owning along with caring for these color superior diamonds.
The coating might be applied to the whole of a diamond’s surface, just the bottom of the diamond, or to a filter zone near the girdle. Some sort of well-applied coating can change the type by one or more colour classes. Some coatings can be removed by way of boiling in acid, powerful cleaning solutions, or even household chemical substances. Sometimes dots or bigger areas of purple or glowing blue ink are painted within the diamond to help counteract the yellowish color. The diamond’s setting will usually cover the actual dots, so they are to be able to see in a mounted rock.
So, is a colour-improved diamond right for you?
Maybe… organic fancy colour diamonds could be beautiful but they are expensive! Colour-enhanced diamonds are inexpensive and allow many people to own the brightly colored diamond. Ask the local jeweler if they have any Nice diamonds…. either natural or maybe colour-enhanced diamonds. It usually is interesting, and fun, to see something different!
Under normal don, the irradiated and HPHT color-enhanced diamonds should have no problems with the colouring fading away. The only thought will be when you need to have almost any service done on the piece. If this type of color superior diamond is exposed to abnormal amounts of heat it might impact the colour.
The jeweler must know that the diamond can be a colour-enhanced diamond prior to any work is done after which the jeweller will be able to choose the best course of action. Color improved diamonds are now also utilized as the small accent gemstones around a larger colorless gemstone. There are many exciting pieces of jewellery provided by small blue, yellow, dark, or green colour improved diamonds.
Now that you know regarding colour enhanced diamonds as well as someone tries to sell a person on what they call an all-natural fancy coloured diamond however it is at a super bargain cost… you will know that something only does not sound right about the present. A report from a respected grading lab should accompany natural and organic Fancy coloured diamonds which might be marketed as natural.
When you deal with a reputable company and also been reassured about what you will be buying, then you will lessen the opportunity of something bad happening to you. Products or services situations involving an expensive getting something that not many people are trained in, education should be a necessary part of your plan. It is even more important if you plan to purchase some sort of colour-enhanced diamond.
