Sapphires

Sapphire is a gemstone variety of the mineral corundum, an aluminum oxide, when it is a color other than red or dark pink, in which case the gem would be a ruby, considered a different gemstone. Trace amounts of other elements such as iron, titanium, or chromium can give corundum blue, yellow, pink, purple, orange, or greenish color. Pink-orange sapphires are padparadscha. Pure chromium is the distinct impurity of rubies. However, a combination of e.g. chromium and titanium can give a sapphire of a color distinct from red. Sapphires are a part of many jewelry settings. Sapphires found naturally by searching through certain sediments or rock formations, or manufactured for industrial or decorative purposes in large crystal boles. Because of the remarkable hardness of sapphires , sapphires are used in some non-ornamental applications, including infrared optical components, such as in scientific instruments; small, high-durability windows ; wristwatch crystals; and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics . The sapphire is one of the two or three gem-varieties of corundum, with another one being the red or deep pink ruby. Although blue is their most known color, sapphires make up of any color of corundum except for red. Sapphires may also be colorless, and found in shades of gray and black. The cost of natural sapphires varies depending on their color, clarity, size, cut, and overall quality - as well as their geographic origin, oddly enough. Significant sapphire deposits are found in Eastern Australia, Thailand, Sri Lanka, Madagascar, East Africa, and in North America in a few locations, such as at Gem Mountain, and in or near the Missouri River in the region around Helena, Montana. Sapphire and rubies found together in the same area, but one gem is usually more abundant. Color in gemstones breaks down into three components: hue, saturation, and tone. Hue is the color of the gemstone. Saturation refers to the vividness, brightness, or colorfulness of the hue and tone is the lightness to darkness of the hue. Blue sapphire exists in various mixtures of its primary and secondary hues, various tonal levels and at various levels of saturation. Blue sapphires evaluated based upon the purity of their primary hue. Purple, violet, and green are the most common secondary hues found in blue sapphires. Violet and purple can contribute to the overall beauty of the color, while green considered distinctly negative. Blue sapphires with up to 15% violet or purple are to be of fine quality. Blue sapphires with any amount of green as a secondary hue are not fine quality. Gray is the normal saturation modifier or mask found in blue sapphires. Gray reduces the saturation or brightness of the hue and therefore has a distinctly negative effect. The color of fine blue sapphires described as a vivid medium dark violet to purplish blue where the primary blue hue is at least 85% and the secondary hue no more than 15% without the least admixture of a green secondary hue or a gray mask. Yellow and green sapphires found regularly. Pink sapphires deepen in color as the quantity of chromium increases. The deeper the pink color the higher their monetary value as long as the color is trending towards the red of rubies. Sapphires also occur in shades of orange, brown, and colorless sapphires sometimes used as diamond substitutes in jewelry. Padparadscha sapphires often draw higher prices than many of even the finest blue sapphires. Recently, more sapphires of this color have appeared on the market result of a new artificial treatment method that is lattice diffusion.

Poker Ante

An ante is a forced bet in which all players put an equal amount of money or chips into the pot before the deal begins. Often this is either a single unit a one-value or the smallest value in play or some other small amount; a proportion such as a half or a quarter of the minimum bet is also common. An ante paid by every player ensures that a player who folds every round will lose money though slowly, thus providing all players with an incentive, however small; to play the hand rather than toss it in when the opening bet reaches them.

Antes are the most common forced bet in draw poker and stud poker but are uncommon in games featuring blind bets see next section. However, some tournament formats of games featuring blinds impose an ante to discourage extremely tight play. Antes encourage players to play more loosely by lowering the cost of staying in the hand calling relative to the current pot size, offering better pot odds. With antes, more players stay in the hand, which increases pot size and makes for more interesting play. This is considered important to ensure good ratings for televised tournament final. Most televised high stakes cash games also use both blinds and antes. Televised cash games usually have one of the players pay for everyone, normally the dealer, to accelerate play. If there are six players for example, the dealer would toss six times the ante into the pot, paying for each person.

In live cash games where the acting dealer changes each turn, it is not uncommon for the players to agree that the dealer or some other position relative to the button provides the ante for each player. This simplifies betting, but causes minor inequities if other players come and go or miss their turn to deal. During such times, the player can be given a special button indicating the need to pay an ante to the pot known as "posting"; see below upon their return. Some card rooms eliminate these inequities by always dealing all players into every hand whether they are present or not. In such cases casino staff or neighboring players under staff supervision will be expected to post antes and fold hands on behalf of absent players as necessary.

Playing Cards

A playing card is a piece of specially prepared heavy paper, thin cardboard, or thin plastic, figured with distinguishing motifs and used as one of a set for playing card games. Playing cards are typically palm-sized for convenient handling.

A complete set of cards is called a pack or deck, and the subset of cards held at one time by a player during a game is commonly called a hand. A deck of cards may be used for playing a great variety of card games, some of which may also incorporate gambling. Because playing cards are both standardized and commonly available, they are often adapted for other uses, such as magic tricks, cartomancy, or building a house of cards.

The front or face of each card carries markings that distinguish it from the other cards in the deck and determine its use under the rules of the game being played. The back of each card is identical for all cards in any particular deck, and usually of a single color or formalized design. Usually every card will be smooth however some decks have braille to allow blind people to read the card number and suit. The back of playing cards is sometimes used for advertising. For most games, the cards are assembled into a deck, and their order is randomized by shuffling.

Slot Machines are Slots

Slot Machines

Slot machines were introduced around the turn of the century, and their popularity increases daily. For many players, playing slots is still the most enjoyable and relaxing form of gambling.

These so called 'one-armed bandits' can be found in every casino, with a variety of models and coin denominations to please every player, including mechanical, electromechanical video, and the new touch-screen versions. With one touch of the screen, you can change from poker to slots. There are three to nine reels, criss-crosses, multiples, progressives, and specialty machines such as 21, Keno, Video Poker, Poker Bingo, and Video Horse Racing and Dog Racing. My favorite is the $.25 wheel of fortune slot machine with reels.

There are many different slot machine games. Jackpot size, combinations, symbols, size and number of coins allowed in each play vary as well. Included in these games are the popular Video Poker games. Modern slot machines are completely electronic. Symbol combinations come up randomly and machines are pre-programmed to return a certain percentage to the players.

Slots account for a good portion of a casino's action and winnings. They are simple to use, inexpensive to maintain, and require little or no skill to play.

To the player, a slot machine returns on average between 85% and 98%. The average casino advantage is calculated to be around 9%.
