Diamonds, precious and rare.

Extracts from this document...

Introduction

'True friends are like diamonds, precious and rare; false ones like autumn leaves, found everywhere'. This is one of the beautiful American proverbs which clearly define diamonds. Diamonds are precious stones of pure carbon in crystal form. The word diamond came from a Greek word 'Adamas' which means unconquerable. Diamonds are the most expensive and valuable of all jewellery as they are the hardest material known on earth. Every diamond is different whether they are detectable or not to the naked eye. Each diamond has various significant characteristics that make it unique. To ensure that diamonds are of the highest quality they are evaluated by jewellers using the Four Cs method. The method includes colour, clarity, carat and cut. Diamonds are found in all the colours of the rainbow including faint yellow, brown, rare pinks, greens, blues or dark reds etc. Collectively these coloured diamonds are called 'fancy coloured diamonds'. The strongly coloured diamonds are called fancies. ...read more.

Since diamonds are so small and light, carats are broken down into decimals called points, with 100 points in each carat. Most of the common sizes of diamonds in jewellery range from .01 to 3 carats. Cut of the diamond is very important because of the 4C's, the cut is the aspect directly influenced by man. The other three are directed by nature. A well-cut and well-proportioned diamond allows the maximum amount of light to enter, reflect and return to the observer's eye. Variations of good proportions show light leaking out of the diamond, which lessens the value of the stone. The clear reflection of light and sparkle value are called the fire of the diamond. If a diamond is cut the wrong way or along improper inclusions lines, the stone can lose a lot of its original value, which is why having a talented and experienced jeweller cutting it is so important. ...read more.

Conclusion

The facets in each show the difference between these three types of cuts. The facets are the edge of the stone that is cut into the diamond. Step-cut diamonds like Emeralds or Banquettes have rows of facets that look like the steps of a staircase because they are elongated and four-sided. Mixed-cut diamonds have both Brilliant-cut and Step-cut facets in them. Some Mixed-cut diamonds include Radiants, which are rectangular or square shaped stones with step or scissor-cut on the crown and Brilliant-cut on the pavilion. Barion Mixed-cut diamonds were the first square stone on the market with a traditional Step-cut crown and an altered Brillian-cut pavilion with 62 facets. The largest diamond in the world is the Millennium Star, which has 777 carat. So in short the 4Cs method of evaluating diamonds helps you to determine the best qualities of the stones. Hence each feature of the 4Cs method is essential to a diamond's value. So next time when you go to purchase diamonds for yourself or your loved ones don't forget to evaluate the diamond by the 4Cs method. ...read more.
