According to Wikipedia, a gemstone (also called a gem, fine gem, jewel, precious stone, or semi-precious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks (such as lapis lazuli and opal) and occasionally organic materials that are not minerals (such as amber, jet, and pearl) are also used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone. This square shape gemstone image was generated with computer software.

Rock formations and land use in Wyoming. False- colour infrared image of the Bighorn Basin in Wyoming, USA. The Bighorn River is seen running from top to bottom near the right. The Shoshone River runs from bottom left, meeting the Bighorn near top right. The northern (upper) bank of the Shoshone has a large aggregate of irrigated fields (blue/purple). At bottom right the line of Dry Creek is seen, with a smaller aggregate of fields just right of bottom centre. The banded rock formations appear multicoloured, and are particularly clear. This image was made by the Thematic Mapper of a Landsat satellite in 1991.

A long section of shoreline along the Pacific Ocean in San Diego is known as the Cabrillo Tidepools area. A great environment for an exciting visit as you will never know what to expect every time you visit. Once the water recedes during low tide, many species of sea life remain trapped in the nooks and crannies created by the rock formations. You’re likely to see starfish, anemones, crabs, fish, and if you’re lucky, you might even catch a glimpse of an octopus. I am told that there eve many secret caves. Unfortunately during my short visit to the area I did not see any marine life nor any secret caves. All images are taken with a Canon 5D III (full frame) and a Canon 7D II (crop frame) using a variety of Canon L-Series lenses,...
