Laser drilling is a technique used to remove inclusions such as black spots of non-crystallized carbon or foreign crystals embedded into the diamond. … The clarity of diamonds whose inclusions have been removed through laser drilling can usually increase by up to one grade (sometimes more).
How do you hide diamond inclusions?
A ring with a prong setting will hide an inclusion on the diamond’s girdle, and bezel settings will hide inclusions on the pavilion. On the other hand, diamond cuts with step-cut facets are more likely to show inclusions.
What are the worst inclusions in a diamond?

Can an inclusion in a diamond get worse?
Diamond inclusions are internal flaws that developed within a diamond at the time of its crystallization, millions of years ago. The safest diamond clarity grades are in the SI range and higher. Once formed, inclusions don’t grow or change; they can sometimes be removed through clarity enhancement techniques.
How do you remove impurities from a diamond?
At the end of the manufacturing process, before they are sorted as polished, diamonds undergo a boiling process – basically, “cooking” that removes all the foreign substances stuck to the diamond. There are two kinds of boiling – regular and deep boiling, also known as deep cooking.
Are inclusions good in a diamond?
Inclusions are small imperfections within a diamond that are created due to the extreme pressure and heat that diamond’s experience when they form. … Diamonds with large inclusions, or a large number of inclusions, will have a low clarity grade. You want to avoid diamonds with fair or poor clarity grades.
Do round diamonds hide inclusions?
Inclusions are usually not noticeable in round diamonds, so buyers can go a bit lower on the clarity scale. Choose a diamond with an SI1 or SI2 clarity grade or higher. … As a result, round diamonds are better at hiring hide low color grades.
Do inclusions affect a diamond’s sparkle?
Clarity will affect how the diamond sparkles and looks under light — and fewer inclusions means the diamond will shine more brightly under the light.
How do you see inclusions of a diamond?
You’ll know there’s a cloud inclusion in your diamond if you see a circle made up of small red dots or pinpoints on the diamond grading report. If they’re tiny and subtle, clouds don’t really pose a threat. But if they’re too big, they can make the gem look hazy and affect its light performance.
Are SI2 Diamonds bad?
Is SI2 diamond clarity good? … SI2 diamonds tend to have more imperfections and more noticeable inclusions than better grades like SI1 and VS2, but sometimes you can find an eye-clean stone. If you can find an eye-clean SI2 diamond, you’ll get the most for your budget.
Do bigger diamonds have more inclusions?
This is because on average, smaller diamonds have fewer inclusions than bigger diamonds of the same clarity. You are more likely to find a stone whose flaws are not visible or happen to be placed in a not-so-prominent location if the diamond is small rather than big.
What is a dirty diamond?
Human-rights groups call them “dirty diamonds.” They come from the worst hell holes in the world – where ghastly conflicts of which most people are only dimly aware have been raging throughout the 1990s. … It’s the dark side of the diamond industry.
Are cloud inclusions bad?
Cloud inclusions are very unlikely to have any appreciable impact on light performance in the higher clarity grades (VVS and VS). It is in the SI and below clarities that clouds are apt to be large enough or numerous enough to significantly impact the reflection and refraction of light among the diamond’s facets.
What can damage a diamond?
Sudden extreme temperature changes can cause damage, however. Diamonds can chip or fracture from hard impact, especially in areas where the carbon atoms are not tightly bonded. These areas, called cleavage planes, are the major source of damage to diamonds (figure 2).
Can I boil my diamonds?
It’s best for a consumer to not put diamond jewelry in a pot of boiling water, as is suggested by some jewelers. The reason being, that the consumer can cause damage to the diamonds if the boiling is not done properly.
Why does my diamond look cloudy?
A cloudy diamond has inclusions that make it appear hazy in some parts or all of the diamond. … It’s not solely cloud inclusions—those made up of three or more crystal inclusions—that can make a diamond appear hazy. It can be other types of inclusions like feathers and twinning wisps that can cloud the diamond.
