Friendship bracelets are special bracelets
Friendship bracelets are special bracelets. As a symbol of friendship these bracelets are given from one friend to another. The amount of thread used in bracelets can vary. They are handmade and usually made out of embroidery floss or thread. Thicker bracelets are commonly worn by both male and female surfers. There are various styles and patterns, but most are based on the same simple half-hitch knot.
They are particularly popular with pre-teen and adolescent girls and with present-day hippies, deadheads or Rainbow Family participants. The smallest pattern, a double chain knot, requires two strings. The making of friendship bracelets is a version of macrame. Because of their versatility, they are worn by both males and females of all ages. The candystripe can have as few as three strings and as many as forty, based on pattern and thickness.
Popularity of the Indian Silver Jewellery
It might surprise people to find out that the Elements Class contains minerals that are composed of more than one element. Popularity of the Indian Silver Jewellery is associated with the elegance and versatility of it. The most difficult to classify are the metal/non-metal mineral combinations. Elements, by the chemical definition are composed of all the same atoms; whereas substances composed of two or more elements are compounds.
These minerals, which combine metals such as iron with the very non-metallic elements of carbon, nitrogen, phosphorous and silicon, are quite unique and quite rare. But the sulfides class is by convention limited to sulfur and semi-metal combinations as discussed above. They are not too different from sulfides which typically combine metals with sulfur.
Gemstones are identified by gemologists
Gemstones are identified by gemologists. The first characteristic a gemologist uses to identify a gemstone is its chemical composition. Gems are characterized in terms of refractive index, dispersion, specific gravity, hardness, cleavage, fracture, and luster. They may exhibit pleochroism or double refraction. Who describe gems and their characteristics using technical terminology specific to the field of gemology.
Next, many gems are crystals which are classified by their crystal system such as cubic or trigonal or monoclinic. They may have luminescence and a distinctive absorption spectrum. For example, diamonds are made of carbon (C) and rubies of aluminium oxide (Al2O3). Another term used is habit, the form the gem is usually found in. For example diamonds, which have a cubic crystal system, are often found as octahedrons.
