Type 2a Diamond Tester

Every diamond during the formation gains natural elements as nitrogen or boron.

Type 2a diamond tester.

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. However most lab grown diamonds are type iia. Occur but they are not included in the diamond type classification system collins 1982 2001. Natural type iia are extremely rare only 1 2 of earth 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. 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. Never heard about types of diamonds such as 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. In this blue diamond the yellowish area labeled ib contains nitrogen. Nitrogen is the element that gives many natural. Our premium pick product is the innovative and truly unique looking presidium adamas diamond tester which can detect your diamonds from your moissanite simulants and metals instantly it s accurate on diamonds as small as 0 02 ct and with the optional micro tip that accuracy improves to 0 01 ct.

Get to know why type iia diamonds are more expensive. Each type has its own unique tendencies and characteristics. And the colorless area iia is generally free of impurity elements. Type ii diamonds are divided into types iia and iib again see figure 2.

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. Instead type iib diamonds con. Diamonds are separated into five types. The blue area labeled iib contains boron.

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. Diamond type is a method of scientifically classifying diamonds by the level and type of their chemical impurities. 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. 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 fact that this diamond contains both nitrogen and boron which doesn t usually happen with natural diamonds also points to this diamond being synthetic.
