A square, faceted gemstone cut. The princess cut has a broad, flat face area and parallel V-shaped grooves underneath with a border of variously shaped facets. This cut provides excellent light refraction and is a popular for diamonds.
is a cutting style in which diamonds and other gems are cut that is square or rectangular in shape. Princess-cut stones typically have between 57 and 70 facets and varying proportions. Prong is one of several claw-like wires that holds a stone in place in the setting. The most common number of prongs is four or six, although the number can vary depending on the shape of the stone being set. Proportion is the major factors that influence cutting quality, and, thus, its light reflecting and refracting ability. Prong Setting - sometimes called a 'claw' setting, is the most common used to set diamonds and other gems. It is popular for solitare-type engagement rings. Typically, a gemstone is set into three to six metal prongs that form a basket around the stone. Then, the tips of the prongs are carefully bent over and shaped, so that they fit snugly against the stone to hold it in place. When set properly, there will be no space between the prong and the gemstone surface. The visible prong ends are often shaped like a ball on the end, but they can be shaped into ovals, points, "V's", left flat, or even formed into decorative shapes like a "fishtail" or other shapes.
