Carat Weight

Diamond Carat Weight – The term ‘Carat(ct.)’ is a unit of weight measurement used to primarily weigh Diamonds and Gems. It is the most valuable visual C of the 4’c of diamond that is recognized globally. It is vital to understand that diamond carat is to weigh while gold Karat is utilized to measure gold purity, this signifies a measuring scale where one metric carat (1.00 ct.) diamond weighs 0.20 grams.

The larger the diamond, the rarer and expensive it gets.

Total carat weight (t.c.w.) is a phrase that represents the total weight of all diamonds or other gemstones in a piece of jewelry when more than one gemstone is used. Diamond solitaire earrings, for example, are usually quoted in t.c.w., indicating the combined weight of the diamonds in both earrings.

The carat weight has became standardized and has also become a point of reference when looking at the certificate of any diamond regardless of which institution certifies the diamond.

Carat Price Chart

The price of a diamond depends on personal preference and budget. It is difficult to measure the diamond weight simply by looking at it. Although carat weight plays an important role in the cost price of a diamond, it is advised to focus on cut grades and diameter.

For more information, we have designed a Diamond Size Chart to demonstrate how various diamonds differ in size and weight from the top.


Diamond Color Actually means the lack of color.

It is the second most important factor to consider when choosing a diamond. The natural color of the diamond is measured by a grading system which is globally adopted by an alphabetical color scale from D to Z, the highest grade being D, which is the most expensive in value. As the scale goes down, the diamond starts to develop a yellow or brown or grey tint, therefore the less color diamond display, the higher the rarity and price.

It is advisable to choose a diamond grade G H or higher to avoid hue or pale yellow tint.


A cut in a diamond is not only about its shape but how the light passes through it and sparkles from the surface. An ideal cut in a diamond is a perfect combination of three essential features which is brilliance, fire, and scintillation achieved by the diamond cutter. To determine the overall beauty of a well-cut diamond it is important to achieve ideal proportions and angles to refract light through the table & crown of the diamond with fine polish and symmetry grading. A poorly cut diamond, on the other hand, will appear lifeless and dark, regardless of its deeply significant clarity or color.

Diamond Proportion refers to a relationship between shape, size, and angle of each facet of a diamond. For a diamond to show its maximum light it needs to be exhibiting three primary factors: brilliance, dispersion, and scintillation. When the light hits the diamond surface and reflects back to the eye of the observer, is known as brilliance or brightness. It bounces off the mirror-like facets reflecting white light from the table of a polished diamond. When the light enters through the gem, some light is broken down to a rainbow of spectral colors and is reflected back to eye of the observer, is known as dispersion or Fire. The separation of light into flashes of color refers to Fire. Further scintillation is ability of the light to reflect or refract with the movement of a diamond, shown by the sparkling effect on diamonds surface.
