Diamonds have always fascinated women. A diamond is known to be the most beautiful gift given by nature to human beings. It is such a simple gemstone yet so captivating! The right purchase of diamonds can be done by knowing a few basic facts about them. The literature provided along with the diamonds mostly indicates the standards of the diamond but we should have knowledge of those standards in order to judge it. In this article we get to know the basic grading standards useful to make the right purchase of diamonds Colour: Colour grading for diamonds ranges from grade d to z. Grade d to h depict dazzling white diamonds but k onwards the colour starts becoming slight yellowish. A good colour should be judged by exposing the diamond to an ultraviolet light. If the diamonds give out a soft glow or fluorescence that means they will look slight brownish when worn in sunlight hence the glitter would be reduced. But the same thing for grades from k onwards reverses and if it does show fluorescence means the dull colour will look better in the sun. To summarise the above information we can say that (1) The d-f range of coloured diamonds are the finest for the discriminating people who have loads of money (2) The g-h ranged ones are also very bright and also nearly colourless diamonds and when mounted on jewellery they are hard to be differentiated with higher grade ones (3) The j range ones are not so bright and have a slight tint whereas the k and m ranged diamonds have a tint which is noticeable with the naked eye. Cut: The 'culet' is the tiny point at the bottom of the diamond. This should be of very negligible diameter, or else the light will go out from the bottom which decreases light being reflected from the diamond. In short we can say that the culet or the tapering end of the diamond should be as negligible as possible. The narrower the 'culet' the higher grade is the diamond. Carat: Carat weight is the measurement for the mass of the diamond. Larger diamonds are rare and hence more desirable for use as gemstones. Total Carat Weight (t.c.w.) is the term used to indicate the total mass of diamonds or other gemstone present in a piece of jewellery. Hence the certificate for jewellery may contain the term t.c.s. which indicates the mass of diamonds in the particular piece. Clarity: Clarity is measured in grades as per the inclusions present in the diamond. Its range varies from flawless to I. The clarity of diamonds can be categorised as follows

(1)Flawless- It is said to be a perfect stone without any inclusions. (2) Internally flawless - The outer side of the diamond may have flaws but the interior is flawless. (3) vvs1, vvs2 - These diamonds have minute inclusions. (4) si1, si2, si3: These have small inclusions (5) i1, i2, i3 These diamonds have inclusions visible to the eye How to examine a diamond: Judging a diamond with the naked eye requires a lot of experience. But a layman can judge the diamonds keeping in mind some aspects like (i)microscope/loop: the inclusions present in the diamonds can be seen with a microscope or a jeweller's loop which is a 10 x magnifying glass. Most of the jewellers have it and would allow the buyers to use it. (ii)Diamond tester: a diamond tester usually verifies that the stone you are examining is really a diamond. It uses light as a medium. The quality of the diamond cannot be guaranteed through this just the stone can be known. (iii)Certification: A certified diamond purchase is always the best and especially if we are not sure about the quality. The certificates issued by Gemological Institute of America or European Gemological laboratory) are the most reliable of all the certificates. Taking care of your precious stones: Diamonds are always thought to be unbreakable or the hardest in stones. But still they need care to be maintained properly. We can take care of them by not wearing them while doing rough work as they will crack or may sometimes chip too. Moreover they should be stored carefully wrapped in cotton or thin cloth. This prevents them from rubbing with each other or scratching other jewellery. Diamonds should generally be cleaned with a polishing cloth. Dipping in soda for some time and then washing the diamonds may give a sparkle to them. Most of the jeweller's clean diamonds for free and that is the safest and best way. Diamond jewellery has gained a lot of popularity among all forms of jewellery. This article helps the buyer to make the right purchase of diamonds which suits their budget as well as personal style too.
