Natural Fancy diamonds can be very costly and many times extra costly than a similar size colorless diamond. A superb example of a Fancy diamond is the infamous 45.Fifty two carat fancy deep blue diamond, the Hope Diamond, that is on display inside the Smithsonian Natural History Museum in Washington, DC.
A coloration more desirable diamond is a a hundred% herbal diamond that has had its coloration changed. And fine of all, color better diamonds come in a completely extensive selection of colors at very less costly fees!
A little bit of history-
For many, many years it’s been widely recognized that a diamond’s shade will be “progressed” through putting a chunk of colored substance at the surface of a diamond and much like magic… A diamond that had a significant yellowish color could trade to a more attractive near colorless diamond. Unfortunately, this kind of color more suitable diamond ought to trade again to its unique frame color if this coloured substance became by accident removed.
In extra recent years, the generation of coloration superior diamonds has long past extraordinarily high tech. It is now possible to completely alternate the colour of a diamond! These strategies are taken into consideration everlasting as it does stay stable whilst exposed to normal everyday conditions. The coloration will now not fade if uncovered to sunlight or be washed off via harsh chemicals.
How is it executed?
The desired outcome of any of those remedies is to have a extra marketable diamond. A less marketable diamond would be a diamond that has a low frame colour or every now and then a lower clarity. The shade greater diamond treatment businesses recognize if they start off with a certain form of diamond and manner it for a positive quantity of time that they must come to be with a positive coloration however it does no longer usually paintings that manner. This is a technology that does require a few artwork in their techniques… The most effective manner that offers consistent outcomes is the coating technique.
The 3 strategies are as follows-
Process #1- HPHT Color Enhanced Diamonds- High Pressure / High Temperature (HPHT) treatment can enhance the colour of certain kinds of brown diamonds and consequently increase their fee. General Electric has developed a procedure that pretty plenty is a mechanical simulation of a diamond’s advent in nature. The colour better diamond may be heated as much as a completely excessive temperature under a completely high, stabilized strain. Faults in the crystal structure are then rearranged ensuing in an alteration of the diamond’s colour.
Because the conditions of HPHT are very similar to diamond’s unique formation, handiest a properly prepared lab will be able to positively pick out this kind of shade stronger diamond. HPHT become first used to turn yellowish diamonds into more marketable fancy colored more suitable diamonds, but now it’s also used to convert some unpopular brownish diamonds into more suited colorless colored more suitable diamonds.
Process #2- Irradiated Color Enhanced Diamonds- OK… Do now not begin getting all excited due to the fact you saw the word irradiated! This is a one hundred% secure system that is very similar to what’s used to preserve meals by exposing it to a flow of Gamma rays. The coloration improved diamond manner is executed in numerous special methods but the outcomes are all of the identical. You begin with a low color (P, Q, R, etc.) one hundred% natural diamond that has already been cut and polished, then it’s far uncovered to a circulate of speedy electrons. During this a part of the procedure the diamond will turn to a completely darkish color because some of the atoms inside the diamond’s crystal structure have now been dislocated and this in flip has affected the manner light passes through the diamond. Next the diamond is going thru a managed heating (annealing) process, this allows a number of the ones atoms to relocate (partially repaired) in order to achieve a favored coloration.
Process #3- Coated Color Enhanced Diamonds- The coating on polished diamonds refers to a thin artificial layer that alters the shade of the diamond. The coating can either be of the favored color or can purpose a coloured interference-impact. Unfortunately from time to time this manner is finished to mislead a client. It is a enormously clean method to carry out, it has been around for decades (even though the coatings substances are an awful lot better now), and it does now not require a whole lot of high priced excessive tech gadget. Recently, I’ve seen a few purple coated diamonds available on the market, they’re very attractive…. And of direction you would have to purchase them understanding that they’ve been covered and observe your jeweler’s hints approximately proudly owning and caring for those color more advantageous diamonds.
The coating can be applied to the complete of a diamond’s floor, just the lowest of the diamond, or to a slender quarter close to the girdle. A well-implemented coating can exchange the coloration by one or more colour grade. Some coatings can be eliminated through boiling in acid, strong cleaning answers, or maybe household chemical substances. Sometimes dots or large regions of pink or blue ink are painted at the diamond to help counteract a yellowish colour. The diamond’s setting will typically cowl the dots, so they’re tough to peer in a hooked up stone.
So, is a coloration more desirable diamond right for you?
Maybe… Natural fancy color diamonds can be lovely but they’re costly! Color improved diamonds are less costly and allow many human beings to own a brightly coloured diamond. Ask your nearby jeweler if they have any Fancy diamonds…. Either natural or coloration better diamonds. It is continually exciting, and fun, to study some thing special!
Under everyday put on the irradiated and HPHT color more advantageous diamonds will haven’t any issues of the shade fading away. The most effective attention could be while you need to have any type of service accomplished at the piece of jewelry. If this sort of colour stronger diamond is uncovered to excessive amounts of heat it’d affect the shade. The jeweler will need to realize that the diamond is a shade improved diamond earlier than any work is accomplished after which the jeweler may be able to determine on the best path of action. Color improved diamonds are now extensively utilized because the small accessory diamonds round a larger colorless diamond. There are many thrilling portions of jewelry available with small blue, yellow, black, or green colour improved diamonds.
Now which you realize approximately shade stronger diamonds and someone tries to sell you on what they call a herbal fancy coloured diamond however it’s miles at a first-rate bargain price… You will understand that some thing just does now not sound proper about the offer. A document from a respected grading lab have to accompany all herbal Fancy coloured diamonds which are marketed as natural. If you deal with a good enterprise and you have been reassured about what you’re shopping for, then you will lessen the opportunity of something bad occurring to you. As with any state of affairs related to an expensive buy of something that now not many people are properly versed in, training ought to be an crucial part of your plan.
