Why are there black specks in my diamond?

A black spot in a diamond is a carbon flaw. Diamonds are made entirely of crystalized carbon, and these black spots are the result of carbon that never fully crystalized. They’re natural flaws, not man-made, and are a part of the diamond’s inherent structure.

Do fake diamonds have black spots?

“Carbon Spots” are what many local dealers call the darkish inclusions inside diamonds, but many modern fakes these days can actually re-create the look of dark or black colored inclusions, even in glass or plastic imitations.

Can you remove carbon from a diamond?

Microwave-assisted plasma allows to remove carbon based residues as well as black carbon for semiconductor applications and diamond processing. Due to the physical properties, MW assisted plasma is specially designed for fast but smooth etching without the typical ion-attack observed for RIE systems (RF-based plasma).

What does carbon look like in a diamond?

In a diamond, the carbon atoms are arranged tetrahedrally. Each carbon atom is attached to four other carbon atoms 1.544 x 1010 meter away with a C-C-C bond angle of 109.5 degrees. It is a strong, rigid three-dimensional structure that results in an infinite network of atoms.

How do you tell if a diamond is real with a flashlight?

What is carbon in a diamond ring?

One of the most common inclusions is a dark blemish called a carbon spot. Diamonds are but one form of carbon; there are many others and most of them are black. Graphite, charcoal and lampblack are all types of carbon as well and there really isn’t a defined line between the various forms.

Is diamond harder than carbon?

While diamonds are classically viewed as the hardest material found on Earth, they are neither the strongest material overall nor even the strongest naturally occurring material. … If the conditions are just right, carbon atoms can form a solid, ultra-hard structure known as a diamond.

What does the inside of a diamond look like?

Internally, diamonds sparkle grey and white; this is known as the diamond’s brilliance. … A genuine diamond’s brilliance should sparkle enough to keep you from reading the underlying print through the stone. The type beneath other stones like a cubic zirconia, however, will be legible through the gem.

What does a cloud look like in a diamond?

Group of pinpoints / Cloud

A large concentration of pinpoints is called a cloud. A cloud thanks its name to its white color and hazy appearance. Tiny clouds aren’t usually a threat to a diamond’s clarity. But big clouds make the stone look hazy and the diamond doesn’t sparkle as much as it should.

Do diamonds smudge?
