Gel bracelets or jelly bracelets or Awareness bracelets
Gel bracelets or jelly bracelets are an inexpensive type of wristband similar to a large diameter O-ring. Awareness bracelets gained in popularity in the 2004 when the Lance Armstrong Foundation introduced its trademark yellow silicone Livestrong wristband to raise support for cancer research. They come in a variety of colors, and dozens can be worn on each arm.
They have been popular in waves throughout the Western world and elsewhere since the 1980s. By early 2005, silicone wristbands became popular with many charities, such as Make Poverty History and the BBC's Beat Bullying campaign. One style of these wristbands, known as awareness bracelets, carry embossed messages demonstrating the wearer's support of a cause or charitable organization. In general, the color of the band describes its cause, and the colors are often the same as the colors of awareness ribbons.
High quality natural gemstones
We purchase and trade in a wide range of high quality natural gemstones from around the world. Alloys that are composed of semi metals with metals are classified as sulfides but are sometimes listed as elements. For thousands of years, gold has been valued as a global currency, a commodity, an investment and simply an object of beauty. We personally select and purchase rough and cut stones.
They usually share similarities to other sulfides in their physical properties. These minerals are in the Selenides, the Tellurides, the Antimonides and the Arsenides Subclasses of the Sulfide Class. The main difference between elemental alloys and these semi-metal alloys is the presence of covalent bonding in these minerals as opposed to the strictly metallic bonding in pure metals and their metal alloys. Our specialty is top quality cutting.
A diamond is a form of carbon
A diamond is a form of carbon that was created deep within the core of the earth more than 3 billion years ago and brought to the surface by volcanic eruption. In diamond, each carbon atom is bonded to four other carbon atoms in a tetrahedral structure, like a pyramid.
Each link or bond is the same length, and the tetrahedral formation is therefore completely regular. Theoretically a perfect diamond crystal could be composed of one giant molecule of carbon. After the magma cooled, it solidified into kimberlite, where the precious rough diamond is still found today. It is the strength and regularity of this bonding which makes diamond very hard, non-volatile and resistant to chemical attack.
