The Kimberley Process is an international certification scheme that regulates trade in rough diamonds. It aims to prevent the flow of conflict diamonds, while helping to protect legitimate trade in rough diamonds.

Learn About Diamonds

Buying a diamond is not something that is done without some forethought because it is, frankly, an important purchase. Fortunately, the most important elements you need to know are easily remembered because they all begin with the letter C: cut, clarity, color and carat size. There are other components that you may wish to become familiar with, such as girdle and table, and these will be explained as well in the following paragraphs. But “the four C’s” are the most important points to know about. What you learn will go a long way to helping you make the perfect choice.

Learn About Gemstones

A gemstone or gem (also called a precious or semi-precious stone, or jewel) is a piece of mineral which, in cut and polished form, is used to make jewelry or other adornments. However certain rocks, (such as lapis lazuli) and organic materials (such as amber or jet) are not minerals, but are still used for jewelry, and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their lustre or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone. Apart from jewelry, from earliest antiquity until the 19th century engraved gems and hard-stone carvings such as cups were major luxury art forms; the carvings of Carl Fabergé were the last significant works in this tradition.
