If you wish to avoid such hassles, then you need to learn about some of the most important parts of diamond engagement rings. Mount, which is popularly known as the setting, is the part of the ring that tightly and securely holds the center stone in place. The mount in your diamond ring also protects the gemstone from accidental chips and other damages. Another important part of a diamond engagement ring is the side stones. Diamonds, sapphires, or other gemstones that are present in your diamond ring not as the center stone are usually called as side stones. However, it is significant to note that some engagement rings will not have any side stones at all, like a solitaire diamond ring. The sides of the setting, which leads up to the head of your ring, are commonly known as the shoulders. These are often decorated with side stones or accents.
