What is a diamond?

A diamond is a naturally occurring rare mineral. It is made up of carbon, the same element that is found in all organic matter such as fossil fuels, cotton, wood, wool and so on.

What makes them so valuable?

The carbon atoms in the diamond are arranged in a tightly bonded way that makes it the strongest and hardest substance on earth.

Diamonds are not only tough but are extremely resistant to chemicals and heat. It is only possible to burn it when it is exposed to temperatures of over 720° Celsius (in air) or 850° Celsius (in vacuum). Very strong acids such as hydrochloric acid or sulphuric acid have no effect as well.

Their unique structure and their cubic arrangement are the factors that make them strong and lustrous.

What gives their color, clarity and shape?

The crystals of diamonds are subject to varying levels of pressure and heat below the earth’s surface. This alters the crystal characteristics and decides the color, clarity and shape of it.

Where are they found?

Diamonds were formed more than three billion years ago when intense pressure and heat caused carbon containing fluids to crystalize. Most natural ones are found at depths ranging between 150 and 250 kilometers below the earth’s surface. A few have also been found at 800 kilometers’ depth. Later, (million years ago), diamonds were brought to the earth’s surface during volcanic eruptions. These were deposited in rocks on earth’s surface.

The countries with the largest stocks include Russia, Botswana, South Africa, Angola, Australia, Republic of Congo and Canada.

What are synthetic diamonds?

Synthetic or man-made diamonds are created in labs. These lab-grown varieties look similar to natural ones as the procedures and methods used to create synthetic ones are the same. Synthetic stones also have the same crystal structure that natural ones have. The difference lies in the fact that natural ones that were formed billions of years ago are unique, rare and extremely special.

How are they polished and cut?

When you buy a GIA diamond or the most covered diamond HK has on offer, you may be wondering about the process of polishing them. The stones that are found in the earth’s crust are rough in nature. Jewelry manufacturers refine the stones by cutting and polishing them. The first step is the planning stage where the shape of the stone to be cut is determined to minimize waste and optimize the rough stone’s yield. The rough stone is split into different pieces using specialized tools. Bruting is performed to give a round shape to the split rough stones. Next the round shaped stone is polished where facets are created. The rough is placed on a rotating arm while a spinning wheel polishes the facets, creating brilliant finished products.

What is a GIA diamond?

Many consumers would have heard of GIA diamonds or GIA certified diamonds. One of the most recognized certification entities is GIA or Gemological Institute of America. GIA is based in California and has eleven campuses, 4 research centers and nine laboratories across thirteen countries. Professional gemologists use standardized assessment techniques to assure the authenticity and reliability of a particular stone. A GIA diamond is one that meets GIA’s standards with respect to clarity, color, cut, and carat weight.

What are certified and non-certified diamonds?

Many independent labs and entities across the world evaluate gemstones and offer grading and certification services. The independent gem lab has expert gemologists who scientifically test and assess the quality. The lab then issues a report or certificate on the gemstones. Many certified diamonds have the certification number laser inscribed on its edge.

Apart from GIA, the American Gem Society Laboratories or AGSL is another certification entity based in Nevada, U.S. The lab specializes in grading of gemstones and has developed its own color, cut and clarity standards. The IGI or International Gemological Institute in Belgium certifies jewelry and colored stones apart from diamonds.

Why should I only buy certified diamonds?

In terms of appearance, there is no difference between a certified and non-certified diamond. However, when you are investing heavily, buying a certified diamond in HK is recommended.

A certification proves the gemstones you are buying are natural, genuine and is of reliable quality.
