The material that is similar in look to the diamond is known as diamond
simulant. At present it plays an important role in the diamond simulant
industry.

The diamond simulant has the same characteristics of a real diamond. With
the diamond simulant or the manufactured diamond, the simulant can be
made of artificial material. It can be a natural or it can be combination
with both. The diamond simulant is different from the synthetic diamond
and the major difference is the material properties. In the case of a
synthetic diamond, the properties are same as the natural diamond. The
diamond simulant has dispersion and hardness properties like natural
diamonds and their properties help in imitation. The differences in a
diamond simulant and in synthetic diamond can be found by diamond
professionals only.

The common simulants that are used in the manufacturing of a diamond are
the leaded glass and the cubic zirconia. Leaded glass is also known as
Rhinestones. The other materials that are used rarely in manufacturing
diamond simulant are strontium titanate and the synthetic retile. But
today, the moissanite plays an important role in manufacturing of a
diamond stimulant even though it is costly when compared to leaded glass
and the cubic zirconia.

The following properties must be possessed by the diamond simulant to
have a great look and fine craftsmanship.
•     The diamond simulant should look like a natural diamond.
•     The diamond simulant properties should be similar to a diamond.
•     The diamond simulant should cater for non-destructive testing
otherwise the fine finishing will not be achieved.
•     It should match the durability and the density test as per the
standard laid down process.
•     There should not be any scratches on the diamond simulant, other
wise it will be distinct from the natural diamond

•     The diamond simulant should be hard in nature comparing to other
gems.
•     The manufactured diamond should have crisp and sharp edges to
provide a sparkling look.
•     They should be flawless and should cater for fine polishing.
•     The diamond simulant should pass the window panel test.
•     The specific gravity of the manufactured diamond should be around
3.5, so that it resembles the natural diamond.
•     The diamond simulant should be of same weight with that of real
diamond.
•     The diamond simulant should match the optics and color properties
with that of the natural diamond.

Artificial simulants
Nowadays the simulants of the diamonds are carried in large masses to
cater the needs of the diamond simulant industry. Due the improvements in
various technologies it has become very easy to manufacture diamond
simulants and these simulants look more original than the natural
diamonds.

At present there are two distinct methods to manufacture the diamond
simulant. One of the method is the high pressure and high temperature and
commonly known as HPHT method. In this method, two presses are used to
maintain the constant temperature and pressure. The two presses are the
belt press and the cubic press. This is one of the cheapest methods to
manufacture a diamond simulant.

The second method that is used is the chemical vapor deposition, which is
also called as CVD method. In this the energy used to create plasma in
which the gases are broken down to form the diamond on the top and the
diamond simulant is provided with fine shapes and is cut into required
sizes.
