A solitaire diamond ring will be really expensive since the entire ring has to look stunning with just a single stone. As it has to excel in every quality, such as cut, color, carat weight, clarity, etc., it will be relatively pricier.     If you wanted to buy cheap diamond solitaire rings, you must be very careful regarding certain things. For one, the cut is the most important feature of a diamond since it will directly affect the fire and scintillation of your stone. So you can make a gemstone of even medium color and clarity grade supreme by choosing an excellent cut grade. There are mainly three types of diamond cuts: shallow, normal, and deep. Shallow cut diamonds usually offer a mirror-like reflection rather than producing an incredible brilliance. When it comes to deep cut stones, the entire attraction of the stone will be at its pavilion, and hence, it will look much smaller than its actual carat weight when viewed from the top.     When it comes to cheap diamond solitaire rings, the vendors may usually offer such poorly deep cut stones that are really inexpensive. As you will not be able to identify this with naked eyes, buying such stones can still be a good option.
