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.
All gemstones have some characteristics
Many gemstones are used in even the most expensive jewellery depending on the brand name of the designer, fashion trends, market supply, treatments etc. Others are too common and are given a semi-precious status. Most gemstones have good hardness and a high index of refraction.
All gemstones have some characteristics falling short of perfection though; even the seemingly perfect Diamond has four directions of cleavage. Since quartz is everywhere especially in common dirt and dust. Any material that is softer may be scratched during ordinary wear. Nevertheless, diamonds, rubies, sapphires and emeralds still have a reputation that exceeds those of other gemstones.
How Durable is My Gemstone Jewellery?
First of all a note about the hardness and therefore relative durability of gemstones. To measure hardness, the jewellery industry uses the Mohs scale. This gem-trade standard, conceived by Friedrich Mohs in 1812, measures the ability of a gem or mineral to resist abrasion damage.
Diamond at 10 is the hardest whereas talc at 1 is the softest. Popular gemstones like amethyst and citrine register 7 whereas rubies and sapphires register 9. Most of us come off the beach on the first day with the 3 sís all achieved - rings caked in sand, sea-salt and suntan lotion. Nude sunbathing, as far as silver and gold jewellery is concerned, is a must! Remember also that sand will scratch the surface of precious metals.
