Zirconia (CZ) is one of the most frequently bumped into diamond simulant.
All marketable CZ is formed synthetically in laboratories however, it
is also found in nature as a natural resource. In both its synthetic
and innate forms, CZ is colorless but color can be induced in it which
enables the fake market to sell them at highest prices claiming it to
be pink diamonds, etc. A thermal pen tester which is a potential testing
equipment that can quickly and easily detect CZ.
Synthetic moissanite is a newly created
diamond simulant that has leaped up to join the long list of products
that imitate or look similar when compared to diamonds. Although moissanite
is marketed currently as a novel unique,
synthetic gemstone, some of its properties are somewhat similar
to those when compared with other diamonds hence it lead experts in confusion
while trading. Synthetic moissanite is a diamond simulant similar to
the Cubic Zirconia however; it can be cleared of its stake mainly because
of its usage as a diamond with the use of thermal pen testers
as it has analogous thermal properties to diamonds. However, it
can also be identified without any problems by other testing methods.
