All About Diamond

For centuries, diamonds have been desired and coveted. While rubies, sapphires, emeralds, and other coloured gems are vibrant and beautify jewellery with their exotic shades, it is the diamond that sparkles with fire, adding brilliance to any piece. The diamond has long been a symbol of love, status and privilege, and continues to be one of the most appreciated gems worldwide.

Diamond Formation

Diamond formation.jpg

Diamonds are formed when carbon deposits in the earth come together under high temperature and pressure conditions for an extended period. It is difficult for these conditions to remain consistent in a volatile environment, thus making the diamond a rare gemstone.



The diamond, its term derived from the Greek word 'Adamas' which means invincible, is the most durable of all gemstones. Temperature and pressure conditions cause the carbon atoms to bond closely, making the diamond resistant to any form of wear, heat and chemicals.



Own Color Scale.jpg

Diamonds are graded on a color scale from D to Z, D being colourless and Z being light yellow. Colourless diamonds are rare, so a D coloured diamond is more valuable than others.

On the other hand, diamonds also come in an array of colors like pink, blue or red. We call them fancy coloured diamonds. A deeper colour increases the value of a fancy coloured diamond.



Clarity.jpgDiamonds are graded for clarity from Flawless (Fl) to Included 3 (I3). Pure diamonds are extremely rare, commanding top prices. Most diamonds have some impurities, though visible only under 10X magnification.



Diamond Shapes.jpgThe cut of a diamond depends on its proportions, polish, and symmetry. A "well-cut" diamond is bright, fiery, symmetrical, and sparkles with light. Diamonds are graded for its cut on a scale from Excellent (Ex) to Poor (P). Diamonds with the Excellent cut grade can command high prices especially in sizes over 1.00ct.



One carat is weighed at 0.200 grams, and is divided into 100 points, just like cents in a dollar. As large diamonds are rarer than small diamonds, they also cost more per carat.

Diamond Pricing


The Rapaport Price List is the primary source of diamond prices information for the diamond trade and is commonly used by dealers as an approximate guideline for evaluating diamond prices. Readers should understand the kind of prices quoted, standards used to describe the diamonds referred to in the List, the limitations of the List and how it can be used to aid buyers and sellers. The price lists are published online every midnight Thursday.

Diamond Treatment

For as long as diamonds and gems have been bought and sold, people have found ways to increase their value and make them more desirable through artificial enhancements. Diamonds are also subjected to treatment processes, sometimes either to improve their colour or clarity, or both.

Synthetic Diamonds

Synthetic diamonds are grown in laboratories and like natural diamonds, possess the same chemical composition and crystal structure.

Diamond Simulants

Diamond simulants imitate a natural diamond's appearance, and can be found in the market at much lower prices. They can be made out of a variety of elements, such as glass, minerals, or other synthetic materials.

Diamond Mines Around the World


Diamonds have been found in countries such as India and Brazil. However, Africa remains one of the significant diamond producers joined by Russia and Canada.

Conflict Diamonds

More commonly referred to as 'blood diamonds', they are used to fund military action in opposition to internationally-recognised governments.

Kimberley Process

Our diamonds are closely monitored through the Kimberley Process, which sieves out conflict diamonds before they enter the market. Today, over 99% of all diamonds available in the market are certified by the Kimberley Process as being free from conflict.
