A diamond can be divided into three parts: crown, girdle and pavilion. Basically, the 4 Cs standard of a perfect ring are cut, color, clarity and carat. The quality of ring’s cut can be directly reflected by facet arrangement; shape and style are the other two major factors that affect diamond ring selecting. In this case, we want neither the crown of the ring too shallow nor the pavilion is too big. As per GIA clarity scale, you do not want the color of the stone less than Si 1 as well. There are also colorless diamond arranged from D. E. F. to G. H. I. J., among which categories D. E. F. are equally preferable. In terms of carat, it is necessary to bear in mind that “Bigger is not better.” In addition, you may intend to take lab created diamonds into consider as one of all your options. Under condition-matched circumstances, lab crested diamonds are exactly same as natural diamonds, with exact element and structure. It does not matter how the stone formed, however, it does where. What is more? It might be a better idea to select the loose diamond and its setting separately. On the one side, Diamonds are available in various sizes and shapes, including oval, pear, heart, square, rectangle and marquise etc. On the other side, platinum, yellow and white gold are main choices for ring settings. You may be able to balance the cost by buying a wedding ring with a high number of carats and set in a less expensive setting. And last but not the least, before the end; can I be honest with you? If this ring is prepared for a “YES, I DO” event, perhaps pick-it-out-herself is a favorable way to select a perfect wedding ring, by which one it looks good on her finger and suit her lifestyle best.
