Quick Answer: What is a Type 2 diamond?

What is the difference between Type 1 and Type 2 diamonds?

Type I diamonds are the most common. They represent 98% of all natural diamonds and have detectable traces of Nitrogen. Type Ia stones contain clusters of Nitrogen atoms throughout the crystal structure of the stone. … Type IIb diamonds contain elements of Boron within the structure.

What is Type 1a diamond?

Type 1a. If the nitrogen atoms are clustered together within the carbon lattice, then the diamond is said to be a Type 1a diamond. Because these diamonds absorb blue light, they can have a pale yellow or brown color. 98% of diamonds are Type 1a.

Are Type IIa diamonds more expensive?

These stones are 0.1% of all diamonds and emit a strong yellow, orange, brown and even green color tone. Type IIa diamonds are the most valuable and consequently are very collectable items.

What are the 5 types of diamonds?

Diamonds are separated into five types: Type Ia, Type Ib, Type 1aB, Type IIa, and Type IIb. The impurities measured are at the atomic level within the crystal lattice of carbon atoms and so, unlike inclusions, require an infrared spectrometer to detect.

Are all lab grown diamonds Type IIa?

Every colorless lab grown diamond is classified as Type IIa—the purest type of diamond. Less than 2 percent of the world’s mined diamonds are pure enough to be classified as Type IIa. Beyond those two points, there is no difference between lab grown and mined diamonds.

Are IGI diamonds good?

While IGI is a reliable lab, it is still not as strong as GIA. … Moreover, buying an IGI diamond with lab reports from their more established labs in the U.S. and Europe might be a good ideal. It is also important to note that IGI is not as inconsistent in low grade diamonds as they are in high grade diamonds.

What is the cheapest type of diamond?

Carat-per-carat, emerald and Asscher cuts are the least expensive. Because they are step-cut, there is less waste when these diamonds are cut off of the rough stone, which is going to cost the same no matter how it gets cut.
