Gia will grade laser drilled diamonds marking the laser drill holes on the inclusion plot.
Laser enhanced diamonds.
Figure 2 is a sample picture from their site.
Laser drilling is a way to enhance the clarity of a diamond.
You need to understand that clarity enhanced diamonds usually originate from garbage tier quality diamonds that are unwanted and unsaleable.
The tunnel in a laser drilled diamond is so small just 20 25 microns in diameter that it doesn t affect the weight of the diamond.
The clarity of the diamond is usually enhanced by laser drilling or fracture filling while the stone s color can be enhanced by high pressure high temperature treatment hpht.
Meaning they are usually stones that were i1 i2 or i3 in clarity and being that no one wants a diamond with eye visible inclusions a jeweler or a person with that stone will have the inclusion s treated to be made invisible to the naked eye.
These include clarity treatments such as laser drilling to remove black carbon inclusions fracture filling to make small internal cracks less visible color.
Now if you are wondering whether laser drilled diamonds or any form of enhanced stones are good buys let me tell you straight up that you will be sorely disappointed.
The change in appearance of the laser drilled diamond is permanent.
Many diamonds mined from the core of the earth undergo some sort of treatment in the laboratories before they are rolled out in the market but those that are labeled clarity enhanced are especially treated to look clearer.
Like laser drilling fracture filling needs to be legally disclosed with any purchase.
Laser drilling uses heat or injects chemicals into the diamond to make discolorations and small flaws less visible.
Enhanced diamonds unlike high quality natural diamonds are natural diamonds that have had very specific treatments done to them to improve their characteristics or their natural flaws.
It s smaller than the width of a hair.
The process involves using laser to drill tiny holes thinner than a hair in the stone all the way from its surface to an inclusion inside.
His family currently runs a business called yehuda diamonds where they sell clarity enhanced diamonds both directly on the internet and through partner stores.
One type of treatment is laser drilling which is a process that removes minor inclusions in a diamond to produce a clarity enhanced diamond.
