Diamonds come in 10 different shapes all of which are exclusive with distinctive scintillation and sparkle.
Prices of diamonds vary according to the quality of diamonds in the market, the source of the diamond, and where it was manufactured. However, it is not necessary to get the highest quality of diamonds to purchase something that is equally beautiful and elegant.
One carat equals 200 milligrams in weight.
For diamonds under one carat, each carat is divided into 100 points- similar to pennies in a dollar. 0.75 ct. = 75 points, ½ ct. = 50 points.
A diamond’s value is determined by all 4Cs, not just carat weight.
The GIA Colour Scale extends from D (colourless) to Z (light yellow or brown).
Although many people think of gem quality diamonds as colourless, truly colourless diamonds are actually very rare. Diamonds occur in a variety of colours- steel grey, white, blue, yellow, orange, red, green, pink to purple, brown and black. Coloured diamonds contain interstitial impurities or structural defects that cause the colourisation; pure diamonds are perfectly transparent and colourless.
Colour grades are determined by comparing each diamond to a master set. Each letter grade represents a range of colour and is a measure of how noticeable a colour is.

The GIA Clarity Scale includes eleven clarity grades ranging from Flawless to I3.
Because diamonds form under tremendous heat and pressure, it is extremely rare to find a diamond that lacks any internal and external characteristics. These characteristics are a by-product of its formation and help gemologists separate natural diamonds from synthetics and simulants, and identify individual stones.

The GIA Cut Scale ranges from Excellent to Poor.
A polished diamond’s beauty lies in its complex relationship with light. The magnificent display you see is made up of three attributes: Brightness is the combination of all white light reflecting from the surface and interior of a diamond. Fire describes the “flares” or colour emitted from a diamond. Scintillation describes the pattern of light and dark areas and the sparkle you see when the diamond, the light, or the observer moves.
A diamond’s proportions affect its light performance, which in turn affects its beauty and overall appeal. Diamonds with fine proportions, symmetry, and polish optimise their interaction with light, and have increased brightness, fire, and scintillation.
GIA assesses these factors for standard round brilliant diamonds in the D-to-Z colour range.
A diamond’s value is determined by all 4Cs, not just cut.
Some diamonds can emit a visible light when exposed to ultraviolet radiation, but fluorescence is not a factor in determining colour or clarity grades. However, a description of its strength and colour is provided on GIA reports as an additional identifying characteristic.
Symmetry indicates to the precision of how diamonds facets align as well as how it interacts with light.
Polish refers to the final finish of a diamond used to smoothen out a diamond’s facet to achieve a glass like surface. GIA examines all diamonds under 10x magnification to grade the diamonds final polish features ranging from excellent to poor.
The GIA (The Gemological Institute of America) have set the worldwide standards in diamond grading since 1931 and have continued to lead the grading standards since. Manish sells GIA as well as HRD and IGI certified diamonds, as these are also the world’s leading laboratories and have the strictest and most consistent diamond grading standards.
