The most important characteristic of a diamond is its shape. The finishing and shape of a diamond is considered as vital while making a buying decision as it comes along with the carat weight and price. Diamond shape most called as diamond cut makes each brilliant unique from the other. Though diamond cut and diamond shape are the words used interchangeably but they are different from each other. A diamond shape is the appearance and looks of the diamond whereas a cut includes its symmetry, facets and brilliance. There are various beautiful shape diamonds available in the market while the popular ones are Round, Oval, Princess, Heart, Emerald, Pear and Marquise. The shape of the diamond is decided based on the amount of rough stone lost in the cutting process. A diamond cutter always aims to maintain the maximum carat weight and value while cutting the rough stone and giving it a shape.
The cut of a diamond plays a crucial role as it includes the overall finishing of a diamond. Diamond cut refers to the facets, symmetry, detailing, angles, fire and proportion. The ability of the diamond to sparkle to its fullest depends on its cuts. A cut is the biggest factor that adds beauty to a diamond.
The another important aspect is the diamond colour which again is difficult to identify visibly. A diamond can be icy white colourless to light yellow. Colourless diamonds are rare and highly expensive while the diamonds that have colour are least rare and cheap. It is always suggested that an expertise advise is important while examining the colour of a diamond.
The clarity of a diamond refers to how clean a diamond is without imperfections. The GIA has created a grading list based on the clarity for buyers to understand the worth of each diamond. A diamond without impurities and faults is considered as flawless and is found to be rare and expensive.
The carat of a diamond is the weight of it and not the size. Just like cut, colour and clarity the carat plays an important while making a buying decision. The carat differs across different shapes and sizes of the diamond. Two diamonds of the similar shape and size may vary in their carats. The price of higher carat diamonds is more as they are more desirable and rarer.
Man-made diamonds commonly known as synthetic diamonds or lab created diamonds are the replica of mined diamonds. These diamonds have similar chemical and physical properties as the diamonds that are formed through geological processes. These diamonds are as precise as natural diamonds but cost 30% less than the natural diamonds. They are crafted in laboratories or factories with the use of advanced technologies. Made with utmost care and detailing, these diamonds are so subtle and flawless that even a trained gemmologist or jeweller cannot distinguish between a natural diamond and a manufactured one with the naked eye. These lab grown loose diamonds can be formed in any shape and size. There is a high rise in the demand for synthetic diamonds because of their transparency, price and environmental reasons.
Lab created diamonds have the same quality and optical properties as natural diamonds.
Lab created diamonds contribute excellent value, and are more affordable than natural diamonds

The characteristics and properties of a lab grown diamond depends on how it is been formed. Unlike natural diamonds that grow under immense pressure and heat over a million of years, these diamonds are made by man in a similar way but within couple of weeks. There are 2 processes that are used to create synthetic diamonds – High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
HPHT diamonds are formed with three manufacturing processes – the belt press, the cubic press and the split sphere (BARS) press. Amongst these three one is used to create an environment for a diamond to grow by applying high pressure and temperature. The formation of diamond in HPHT begins with placing a diamond seed into carbon. The seed is then exposed to an extreme temperature of about 1500-degree celsius and is pressurized to 1.5 million pounds per square inch. The carbon then melts and starts forming into a diamond which is later cooled down to form a pure diamond.
The CVD diamond process starts by placing a diamond seed in a sealed chamber which is heated to around 800-degree celsius. That sealed chamber is filled with numerous gases like carbon, methane and others. These gases are then converted into plasma with the help of technology like microwaves or lasers. This process helps break the molecular bonds in the gases and the carbon coheres with the diamond seed, forming a new, beautiful crystal.
Lab created diamonds and natural diamonds both look like each other. They have the same characteristics, chemical and physical properties. The main difference between them is where they are formed. Lab created diamonds are crafted in laboratories with methods like HPHT and CVD within couple of weeks. Natural diamonds take millions of years to form through geological processes. The manufacturing process of created lab diamonds is environment friendly and highly sustainable. Hence there is a rise in the demand of synthetic diamonds. The price of man-made diamonds is less than that of natural diamonds. It is impossible to tell the difference between the two visibly, hence certification is what matters here. The factors that are considered in both while making a buying decision are price, look, 4C’s, sustainability and value.
Lab grown diamonds are real diamonds that have the same chemical structure as natural diamonds. They are grown in laboratories using advanced processes and technologies. Whereas diamond stimulants can be real or artificial and they have different physical properties even if they look like real diamonds. Diamond simulants are rarely imperfect, but they lack in durability and brilliance. They are not precious and do not carry much value. The most popular diamond stimulants are Cubic Zirconia, Moissanite and Rhinestone. The difference between a lab grown diamond and diamond simulant can be recognised based on the hardness, clarity, colour, carat, weight, cut and price.
