Type 2a Diamond Tester

Occur but they are not included in the diamond type classification system collins 1982 2001.

Type 2a diamond tester.

When diamonds are tested in a lab a major indicator that they are lab grown is when they test as a type iia diamond because they are so rare in. For example a 5 50ct d color if internally flawless round cut diamond costs on an average retail website 800 000 while the same diamond if it were type iia it would cost around 825 000. 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. Nitrogen is the element that gives many natural.

However most lab grown diamonds are type iia. Type ia type ib type 1ab type iia and type iib. Type iia diamonds contain no easily measurable n or boron impurities. Diamond type is a method of scientifically classifying diamonds by the level and type of their chemical impurities.

They can also be gray light brown light yellow or light pink. Each type has its own unique tendencies and characteristics. And the colorless area iia is generally free of impurity elements. Natural type iia are extremely rare only 1 2 of earth grown diamonds are type iia.

The type that a particular diamond belongs to depends on the trace elements that can be found in it and the arrangement of those atoms within the diamond. Never heard about types of diamonds such as type iia. Diamonds are separated into five types. On average a diamond that is certified as type iia is valued at between 2 3 more than the same diamond that is not certified as type iia.

Natural type iib diamonds likewise contain no ir measur able n impurities. Instead type iib diamonds con. The fact that this diamond contains both nitrogen and boron which doesn t usually happen with natural diamonds also points to this diamond being synthetic. Type ii diamonds are divided into types iia and iib again see figure 2.

Type iia means that there s very little if any nitrogen in the diamond. I bought this diamond selector ii 2 to check if the stones in the ring i found earlier this were real and to test if this tester works well or not. The blue area labeled iib contains boron. In this blue diamond the yellowish area labeled ib contains nitrogen.

Every diamond during the formation gains natural elements as nitrogen or boron. Get to know why type iia diamonds are more expensive.
