A ring is an algebraic structure that generalizes fields. It is a set equipped with two binary operations that satisfy properties analogous to addition and multiplication of integers. Ring elements may be numbers such as integers or complex numbers, but they can also be non-numerical objects such as polynomials, square matrices, functions, and power series.
There are many types of rings, but most commonly they are worn as adornment or symbols of betrothal and marital fidelity. They can be made of precious metals or gemstones and can vary in size, shape, and decoration. They can be plain or adorned with jewels, and they can have a circular, semi-circular, or flat cross-section. The shoulders and bezel of a ring may be solid or hollow. Alternatively, the bezel may contain a flat table designed to hold a stone or other ornament.
The ancient Egyptians favored the use of signet, or seal, rings, which had the wearer’s name engraved deeply into an oblong bezel. These were used to authenticate documents written in hieroglyphics. The Greeks tended to wear rings for adornment rather than as emblems of status. They were often made of gold and held cabochon stones or vitreous pastes. Later, the Romans took up the custom of wearing rings on their fingers as a mark of prestige. These were frequently of a size that allowed the ring to cover much of the hand, and they were sometimes encrusted with gems.
For modern-day brides, it is quite common to eschew the tradition of having a single solitaire diamond on her engagement ring and instead choose to have a larger, more elaborate ring that showcases a variety of beautiful and meaningful stones. In some cultures, it is even possible to get married without a ring at all.
Many people find themselves in the market for a new ring, whether it be to replace an old one or to mark a major milestone such as a promotion or childbirth. Some may be surprised to learn that there are some interesting things about the way we wear rings and what it says about us.
For example, the ring on which we place it sends a message about our character and beliefs, and even the finger on which we wear it can say something important about how others see us. For instance, in most Western cultures, engagement and wedding rings are worn on the left hand. While a lot of this has to do with culture and religion, the fact is that a person’s left hand is more visible than their right, so it is more likely to be noticed and commented on by other people.
A good tip for those who are trying to shop for a ring is to have a friend or family member who knows the person well try on rings of a similar style and shape to help you figure out the right size. This is particularly helpful if the person has long or short fingers. Oval, pear, or marquise-shaped stones lengthen thin fingers, while rectangular and emerald-shaped stones flatter wide fingers.
