What Are Blue Diamonds?
In order for a diamond to be deemed as a real blue, it must be found in nature and that it hails this hue. A blue diamond that has been enhanced and treated with heat or chemicals is merely a white diamond at its core. With that in mind, it is important that you only buy a blue diamond if it’s GIA certified or that it will be issued at the moment that it will be purchased. The reason why these certificates are so important is that it will indicate the color origin of the stone (Treated or Natural) and will even specify the exact color of the diamond. If the blue diamond is indeed a real one, then it will be stated in the certificate somewhere in the origin where it says “natural.”
You should also know that there are a variety of shades that comes with the blue color in diamonds. There may be some that boasts a pure hue while some may have some undertones or gray, green, or violet. In addition to that, the intensity of the blue color may range from light to vivid. When it comes to the pricing, a slight change in the color can mean a whole lot.
How are Blue Diamonds Made?
When it comes to blue diamonds or the colored ones in general, it comes in two different kinds which are natural blue diamonds and treated blue diamonds.
It’s a remarkable view to see that these blue diamonds can be found in mines boasting its beautiful tone, but the truth is that nature is the one responsible for the stone’s gorgeous hue. So, if you are wondering about the appearance of the natural blue diamonds, what is the one that causes its color? It’s because of the amount of boron in the stone to absorb a red light thus causing it to become blue. To be more specific, this diamond gets its hue when there is boron during the formation of the diamond, and there is only low nitrogen content. The boron content in a blue diamond is also the one that distinguishes the difference between the natural and the artificial stone because of its ability to conduct electricity.
As for the color-enhanced diamonds, these stones are usually colorless when found in nature and then it will be added some color with the use of artificial treatments such as using irradiation and changing the atomic structure of its crystal lattice which will eventually change its all over appearance.
