A finger ring is a circular band worn as a type of ornamental jewelry around a finger; it is the most common current meaning of the word ring. Other types of metal bands worn as ornaments called rings, such as arm rings and neck rings. Rings worn by both men and women and can be of any quality. Various ring shapes and styles exist. The following are but a few. Flat wedding bands are the simplest form of ring. A flat wedding band consists of a strip of metal bent around into a loop and joined where the ends meet. Half-round rings, also called D-shape rings, are flat wedding bands filed half-round on the outside. Sleeve rings are rings that consist of a thin inner ring or sleeve, with several other rings stacked onto it to form one solid ring. Either the rings soldered onto the sleeve or the ends of the sleeve can be upset to keep them all together. A little of both can also be done. Solitaire rings are rings with a single large stone as a centerpiece, usually a diamond. Eternity rings are rings with stones, usually diamonds, of the same cut and size, set in one row all around the ring. The stones are usually round or square, and the setting is usually either claws or a channel setting. When the stones do not continue around the entire ring, but stop halfway around the finger, it is a half-eternity ring. Trinity rings or Trilogy Rings are three rings worn at one time. Cluster rings are rings with a group of stones in a cluster setting, forming the focal point of the ring. The cluster setting usually consists of one large stone in the center surrounded with several smaller stones. Tension Rings are a type of ring in which a single gemstone is held in place by pressure rather than prongs, a bezel or other mounting. The metal setting is actually spring-loaded to exert pressure onto the gemstone. In the United States and Canada, ring sizes specified using a numerical scale, with quarter and half sizes. An increase of a full size is an increase of 0.032 inch in diameter, or roughly 1/10 inch in inside circumference. Generally, sizes in quarters and halves will not relate conventionally to anything on any known ruler. On one finger alone, a person may vary more than a whole ring size- depending on time of day, work performed, and other swelling-inducing activities/conditions. Therefore, in most cases quarter-sizes are meaningless unless one needs precise accuracy with a particular ring.

Wagering is Gambling

Gambling is the wagering of money or something of material value as the stakes on an event with an uncertain outcome with the primary intent of winning additional money and or material goods. Typically, the outcome of the wager is evident within a short period.

Gaming refers to instances in which the law permits the type of gambling. Gaming and gambling are not mutually exclusive. A gaming company offers legal gambling activities to the public and a gaming control board may regulate the gaming company, like the Nevada Gaming Control Board. However, the English-speaking world does not acknowledge this distinction often. For instance, in the UK, the regulator of gambling activities is called the Gambling Commission not the Gaming Commission.  In addition, the word gaming describes activities that do not involve wagering, especially online.

Gambling is also a major international commercial activity, with the legal gambling market totaling an estimated $335 billion in 2009.

Under United States federal law, gambling is legal in the country and states are free to regulate or prohibit the practice. Gambling has been legal in Nevada since 1931, forming the backbone of the economy of the state. The city of Las Vegas is perhaps the best known gambling destination in the world. In 1976, gambling became legal in Atlantic City, New Jersey and in 1990, under state law, gambling became permissible in Tunica, Mississippi; both of those cities have developed extensive casino and resort areas since then. Since a favorable United State Supreme Court decision in 1987, many American Indian tribes have built their own casinos on tribal lands as a way to provide revenue for the tribe. Because the tribes are sovereign nations, they are often exempt from state laws that restrict gambling and are instead regulated under federal law.

Financial betting refers to the wagering on the price development of a financial instrument at some later date relative to the current price or level of the instrument, against odds offered by a bookmaker. Maximum potential pay-off of the wager is known when the bet is taken and as a corollary risk is known beforehand by being limited to the initial stake.

Financial betting instruments are a type of digital option. The outcome of the wager at settlement is binary, that is, either a win or a loss. Settlement is executed in cash and there is no delivery of the underlying asset. At any point in time prior to the settlement date bets can often be sold, allowing for possibilities to bet on the accuracy of a market move within the fixed limits of zero win loss of the stake and maximum potential win. A fee might sometimes be charged for this service.

The main difference between financial betting and speculation on financial markets using products such as financial spread betting is that the bet must result in a simple binary win or loss based on an event on the underlying financial instruments. This triggers a fixed payout for a win, while with spread betting the payout or loss varies with the price level of the underlying instrument. Within financial floating odds the odds change for a given strike price as the price of the underlying changes. The floating odds company calculates odds for different strikes and how much can be won upon settlement depends on how much is bet at those odds.

Within financial fixed odds betting, the odds are fixed, while the strike price where a win is achieved relative the current level changes. The fixed odds company will calculate how much has to be bet to win a certain amount upon settlement if the conditions of the prediction become true.
