Type 2a Diamond Tester

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.

Type 2a diamond tester.

In this blue diamond the yellowish area labeled ib contains nitrogen. Get to know why type iia diamonds are more expensive. Type ia type ib type 1ab type iia and type iib. 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.

And the colorless area iia is generally free of impurity elements. Nitrogen is the element that gives many natural. Each type has its own unique tendencies and characteristics. However most lab grown diamonds are type iia.

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 iia are extremely rare only 1 2 of earth grown diamonds are type iia. 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. 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.

Type iia diamonds contain no easily measurable n or boron impurities. They can also be gray light brown light yellow or light pink. Occur but they are not included in the diamond type classification system collins 1982 2001. Diamond type is a method of scientifically classifying diamonds by the level and type of their chemical impurities.

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. Natural type iib diamonds likewise contain no ir measur able n impurities. 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. The blue area labeled iib contains boron.

Every diamond during the formation gains natural elements as nitrogen or boron. 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. Diamonds are separated into five types. Never heard about types of diamonds such as 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.
