Some of us are not really happy with the clarity of their diamonds. Here is good news for you. There is a way to get rid of those annoying inclusions and improve your diamond clarity. Let’s see how.
Laser drilling is a technique used to remove inclusions such as black spots or foreign crystals embedded within a diamond.
During this process, a thin channel is drilled with a laser from the surface to the inclusion of the diamond, which is then burned out. After burning out the inclusion, there is an empty space left in that place. The resulting hollow inside the diamond would be still considered a type of flow, but it’s not visible.
As for the tunnel drilled in the stone, it’s usually extremely thin and practically invisible with the naked eye. It can be seen only with a microscope.
The clarity of diamonds after laser drilling can usually increase by up to one grade, sometimes even more.
The downside of laser drilling is that it can weaken the diamond’s structure. That’s not a problem if there are just a few holes drilled, but if the stone has a lot of inclusions removed this way, the resulting cavities and channels can make it easier to break.
After laser drilling, the channels and hollows can be filled with a transparent crystalline substance. This masks the remaining cavities and makes the diamond look better.
It’s important to mention that fracture filling is not permanent. The material used to fill the diamond can melt or crack if a jeweller uses heat to repair your jewellery piece. Besides, once a diamond is fracture-filled, it should not be put in an ultrasonic cleaner as it will damage the filling.
Another downside of fracture filling is that the injected material reflects light differently and can change the stone’s sparkle.
Another way to improve your diamond’s clarity is to have it recut. During this process the jeweller/cutter will cut some material from all sides, removing some of the inclusions. This method works if the inclusions are mostly close to the surface of the diamond. If they are towards the centre, you won’t be able to cut them out.
Exchanging Your Diamond for a Better One
The simplest way to improve your diamond clarity is to exchange it for a better stone and pay the price difference.
All the enhancement methods mentioned above have a cost associated with them. And let’s agree that the additional money you will pay to trade your old diamond in is commensurate with the cost of the other solutions.
In most cases, it turns out that an exchange is the best deal of all options available.
