History of culture behind these beautiful accessories
There is a history of culture behind these beautiful accessories when we look at bangles and beads it reminds us. Beads took many forms. Bangles and bead necklaces were worn by both men and women.
When the remains of Harappa & Mohenjodaro of the Tamil civilisation were discovered, beads and bangles were found. The reason for holding this conclusively was that they were similar to the designs of Mesopotamia & Iran. A lot of bangles in old times were made from dangly coins and Islamic half moons. They were on necklaces and bracelets. But carnelian beads were worn exclusively by women.
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.
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.
