Type 2a Diamond Tester

Diamond type is a method of scientifically classifying diamonds by the level and type of their chemical impurities.

Type 2a diamond tester.

Type ia type ib type 1ab type iia and type iib. Then this can come as a surprise as there are 3 more of these diamond types that are classified by the level and type of their chemical impurities. The synthetic diamond screener ii is developed by presidium to help screen out type iia colorless diamond which is likely to be laboratory grown and created through chemical vapor deposition cvd or high pressure high temperature hpht syntheses from the natural type ia colorless diamond. Each type has its own unique tendencies and characteristics.

Type iia diamonds contain no easily measurable n or boron impurities. Natural type iib diamonds likewise contain no ir measur able n impurities. Diamonds are separated into five types. Nitrogen is the element that gives many natural.

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. In this blue diamond the yellowish area labeled ib contains nitrogen. Type iia means that there s very little if any nitrogen in the diamond. 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.

Never heard about types of diamonds such as type iia. Get to know why type iia diamonds are more expensive. 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. Instead type iib diamonds con.

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. Every diamond during the formation gains natural elements as nitrogen or boron. 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. However most lab grown diamonds are type iia.

Type ii diamonds are divided into types iia and iib again see figure 2. 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. 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. And the colorless area iia is generally free of impurity elements.

Occur but they are not included in the diamond type classification system collins 1982 2001. They can also be gray light brown light yellow or light pink.
