Reasons for the Jewellery
Many reasons for the Jewellery has been used such as Currency, Artistic display, Wealth display, Storage, and Status. Other reasons are:
Functional use - There are many items of Jewellery which are originated as purely functional items but evolved into decorative items as their functional requirement diminished, these items are brooches and buckles.
Symbolism - Jewellery can also be symbolic of group membership. As in the case of the Christian crucifix or Jewish Star of David, or of status, as in the case of chains of office, or the Western practice of married people wearing a wedding ring.
Protection - Wearing of amulets and devotional medals to provide protection or ward off evil is common in some cultures; these may take the form of symbols - such as the ankh, stones, plants, animals, body parts - such as the Khamsa, or glyphs - such as stylized versions of the Throne Verse in Islamic art.
Keeping large amounts of wealth stored in the form of Jewellery in most cultures. And Jewellry used to create Jewellery as a means to store or display coins or in the form of wedding dowries in numerous cultures.
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.
The color is the greatest difference in the metals
The color is the greatest difference in the metals. The elements which include over one hundred known minerals are a diverse class when taken as a whole. The non metals are extremely diverse. Due to the diversity of the non metals subclass there is most of this diversity.
The non-metals include some elements known as semi-metals who share some properties with metals but differ in other characteristics. The hardest mineral known to man is from this subclass, as well as one of the softest. The Metals Subclass and related metal alloys contains metals whose properties are rather similar due to the common way in which they crystallize and bond.
