I'm having trouble deciding which type of diamond to buy. Any advice?

The best way to decide on a type of diamond is to consider the four C's: carat, cut, color, and clarity. Start by looking at the carat size of the diamond you are considering. Larger diamonds tend to have more sparkle than smaller ones and can be more expensive.2 Next, think about the shape of the diamond. A round diamond will give you a more brilliant effect than an oval or marquise diamond.3 Consider the cut of the diamond. A well-cut diamond has a good balance between its weight and size, making it easier to see the facets.4 Finally, look into the color and clarity of the diamond. Colorless diamonds are generally considered the most desirable as they show off the natural beauty of the stone. Clarity refers to the number of visible inclusions in the diamond.
