An engagement ring is an important item for a couple who are planning to get married. It serves as a promise of marriage and commitment to enter into a lifelong relationship. Although it is not a requirement for marriage, it is commonly used in the western society as a pledge of love. Those who are planning to buy an engagement ring have to make sure that they get the right-sized ring. A ring that is too large can easily slip off the finger, while one that is too small can restrict blood flow and cause discomfort. In the UK, ring sizes are measured with an alphabetical scale, ranging from A to Z. For most women, the finger where the engagement ring is worn, which is the second to last finger on the left hand, is usually a size M or N. A size N ring has an inside diameter of 17.1 mm.
Once the size of the engagement ring is determined, it is time to shop for a ring with the right design and material. There are many different types of engagement rings available in size N, and some examples of them include 18 carat gold diamond solitaire vintage engagement ring, 10 carat white gold black sapphire filled ring, 1 carat 925 sterling silver solitaire ring, 9 carat white gold .25 carat baguette diamond ring, and the Kate Middleton/Princess Diana engagement ring. Those who are planning to buy an engagement ring should choose one that suits the taste and personality of the intended wearer.
