The Carat Weight of a diamond is a huge contributing factor and the most visible feature that is considered when comparing its price. A slight difference in weight can make a significant difference in price. "Carat" (ct.) is a measurement unit representing the weight of a diamond, the price of a diamond is directly proportional to its weight. The cut off weights are 0.50ct, 0.75ct, 1.00ct so on and so forth.

Diamonds are not always as colourless as they look to the naked eye. The more colour that the diamond lacks, the higher is its price. While most diamonds exhibit a yellow or brown tinge, a completely colourless variety will allow more light to pass through it emitting maximum brilliance. Since the diamond is shaped like a prism, it acts in the same way. That’s why colour in a diamond acts as a filter and diminishes its fire. A truly colourless diamond will emit a spectrum of colours.

Like all things natural, diamonds too are flawed. Diamonds like all other minerals and gemstones are born with several inclusions that develop during their formation. Although almost invisible to the naked eye, inclusions do decide a diamond’s price. Internal characteristics are known as inclusions while external characteristics are known as blemishes. The list of diamond inclusions include crystal, needles and cloud, whereas chips, scratches, nicks, abrasions, bruises, polishing marks and naturals are considered to be diamond blemishes.

The cut is a diamond's most crucial 'C'. A lot depends on the cut since a diamond's cut can increase or decrease its value. The precision and craftsmanship of a cut makes all the difference in the brilliance of a diamond.

In an ideal cut or perfectly cut diamond the light is reflected back to the observer from the top of the stone emitting maximum brilliance.

Also known as the brilliant cut, round diamonds are the most traditional shapes and that's why they're perfect for a classic look. The round cut diamond is the most popular shape and has evolved from the Old European Cut.
