Wearing a single diamond pendant around your neck is great way to display a beautiful, striking stone. A diamond pendant also makes a fabulous gift to celebrate special occasions, like a loved one’s birthday, a graduation, a 21st birthday or an anniversary. To buy a diamond there are many options to consider, but the most important are the following- Diamond Shape –What shape you want the diamond to be, the most popular for solitaire diamonds are round, square, pear, oval and heart shaped. Carat Weight – the weight of the stone, which can reflect its size Diamond Colour – how white and clear the diamond is Diamond Cut – determines the brilliance of the stone and how much it sparkles Diamond Clarity – the number of flaws or blemishes the diamond might have To understand these areas in more depth and to choose which aspects are most appropriate for your budget take a look at our diamond guide. The next step is to select a setting and chain. Most diamond pendants are set in white gold, yellow gold, rose gold or platinum. A classic setting for a pendant is a traditional claw setting, where the diamond is held in place by a number of prongs which allow light to the diamond from different angles. A modern style is a rub-over setting, where the diamond is held in place by a collar of metal or even sometimes half a collar of metal. With rub-over settings the diamond is more secure then a claw, but will block some light from entering through to it. The length of the chain is also another important decision. The most common lengths are 16inch and 18inch. But the length depends on the height and build of the wearer.
