Almost all diamond necklaces are made of stones which are largely extracted from South Africa. Diamond necklaces are made of selected stones and this involves a complicated process to choose the proper stones to make a magnificent necklace.
How the diamonds are set in the diamond necklaces also affect the value of diamond jewelry. The most commonly used settings in any diamond necklaces or other kind of diamond jewelry are Prong, Bezel, and Channel. Prong settings are the most popular setting for any piece of diamond jewelry.
When buying diamond necklaces one should have a closer look at the way the diamond is cut, its proportion and symmetry. You will also have to choose the stones on the necklace carefully. Ideally clear, colorless stones are the best bet for all types of attire. They will complement most dresses beautifully.
