Portland is a city located in the Northwestern United States, near the confluence of the Willamette and Columbia rivers in the state of Oregon. It has an estimated population of 568,380, and has been referred to as the greenest city in the United States.[6] Portland is Oregon's most populous city, and the third most populous city in the Pacific Northwest, after Vancouver, British Columbia, and Seattle, Washington. Approximately two million people live in the Portland metropolitan area, the 23rd most populous in the United States as of July 2006. Portland was incorporated in 1851 and is the county seat of Multnomah County.[8] The city extends slightly into Washington County to the west and Clackamas County to the south. It is governed by a commission-based government headed by a mayor and four other commissioners. The city and region are noted for strong land-use planning and investment in public transit, supported by Metro, a distinctive regional-government scheme. Portland is also known for its large number of microbreweries and microdistilleries, and as the home of the Trail Blazers NBA basketball team. Portland lies in the Marine west coast climate region, marked by warm summers and rainy but temperate winters. This climate is ideal for growing roses, and for more than a century, Portland has been known as "The City of Roses" with many rose gardens—most prominently the International Rose Test Garden.

Rings

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.
