Prior to that, diamond jewelry was worn almost exclusively by royalty. The earliest example of diamonds being placed in a setting dates from the time of the Norman Invasion of England; at that time, one of the Árpád kings of Hungary, possibly Andrew I, had rough-cut diamonds set into a crown for his queen. However, cut diamonds would not be available for another half-millenium.

The mid-1500’s were an energetic time; Martin Luther of Germany and Henry VIII of England had broken with the Church of Rome; Ivan IV (the Terrible) expanded Russia to its present-day borders, and Ottoman sultan Suleiman extended the Turkish empire as far west as Vienna. It was during this time of ferment that the first diamond-cutters’ guild was formed in Antwerp, located in present-day Belgium. An industry soon developed for the purpose of appraising loose diamonds, giving birth to the modern diamond jewelry market. Antwerp continues to be the center of the international diamond jewelry trade.

The gems that are used in diamond jewelry is 75% science and 25% art. Together, these make up the “4 Cs” that are used to evaluate loose diamonds:

* carat

* color

* clarity

* cut

“Carat” of course refers to the weight of the gem; a carat is equivalent to about 2 decigrams, or a mere 1/150th of an ounce. That means the largest cut, polished diamond in existence – the famed Star of Africa – weighs just a little over 2-1/4 pounds.

Although we generally think of clear or white diamonds, they come in a wide range of colors ranging from crystal-clear white to dark amber. Pink, green, blue and even purple diamonds are not unusual, and some are far more valuable than their white counterparts.

Clarity refers to just that – how clear the stone appears. All natural and artificial diamonds have internal flaws; the fewer or the less apparent these flaws are, the higher the appraisal is likely to be.

These three qualities are objective, and easily measured and quantified. Cut is a more subjective quality; selecting gems that are appropriate for use in diamond jewelry requires a good eye and aesthetic sense.

Of course, loose diamonds are not really jewelry until they are placed in a setting, such as a ring or necklace. Even the finest diamonds’ value can be affected by the setting; it is a value-added aspect of diamond jewelry.

Using a mild detergent and warm water prepare a soapy solution. Leave your ring in this solution for a few minutes. Then using a soft brush clean the diamond, areas like the prongs and other parts of the metal band where there are chances of dust accumulation. Rinse the diamond jewelry in warm water. Finally pat it dry with a lint free cloth. A buffing cloth can also be used to give your diamond jewelry a shine. A wooden toothpick may also be used to gently push away dirt from hard to reach areas.

Ammonia wash

A 1:1 ratio of household ammonia and water can also be used to clean diamonds. Mix ammonia and water in equal parts and soak your diamond jewelry in it for approximately twenty minutes. Use a soft brush to remove dirt and rinse in the solution again. Air dry the diamond by leaving it on absorbent tissue paper. However, fracture filled diamonds must not be cleaned using this method. Also if the piece of jewelry has other precious gemstones in it, consult an expert before using ammonia wash.

Ultrasonic cleaning

Ultrasonic cleaners available at jewelry stores are also useful for cleaning diamonds. Here, in the first step, the cleaner uses high frequency waves which vibrate to create many microscopic cleaning bubbles. These bubbles loosen out the dirt in the cracks and crevices of the ring, including prongs. In the second step a high pressure steamer blasts away the particles. However if your diamond jewelry also includes other precious stones like emeralds and rubies, it would be best to first take the advice of a gemologist before ultrasonic cleaning. Also the GIA does not recommend the usage of ultrasonic or steam cleaners for cleaning diamonds.

Off the counter cleaners

Many cleaners are also available at stores. Your diamond dealer may also have given you a cleaner like the Mr. Clean – all purpose cleaner. Follow the instructions carefully while using such products on your diamond. Avoid using cleaners that contain acid as this may affect the surface of the gemstone. Also if you have purchased the solution from a store that does not deal in diamonds, consult your gemologist before using it. Avoid abrasive cleaners while cleaning your diamond. Toothpaste should also not be used for cleaning as it usually has baking soda or other ingredients that can cause scratches.

Cleaning diamonds on a regular basis ensures that they sparkle for a long time to come. You can clean them once a month or even once a week depending upon your usage. It is recommended that as soon as you note a film buildup, caused due to soap or oil, clean your ring at home. Professional cleaning can be opted for once a year, whereby the ring can be repolished and the jeweler will also check and tighten the prongs of the ring.

Caring

A little care goes a long way in keeping your diamond sparkling and shimmering as ever.

Remove your ring before going into the pool as the chlorine may discolor it over a long period of time.

Avoid using harsh chemicals when you are wearing the ring.

Take your diamond to the jeweler once every year so that it can be checked for loose prongs or other settings that need to be restored.

If you feel that the settings have become loose, wrap the jewelry carefully in tissue paper and take it to the jeweler immediately. Let the jewelry be repaired while you watch.

Do not wear your diamond ring with other rings on the same finger as it may chip while in contact with other rings.

Touch it at its edges and not on the stone as it may smudge.

Storing

Here are a few tips on how to store your jewelry carefully.

Store your diamond in a special case so it does not scratch when it rubs against other jewelry.

Use separate compartments for separate pieces of jewelry.

A cloth bag or a jewelry case meant for the purpose may be a good option. Finally you can also wrap them in separate tissue papers.

Diamonds whether studded in jewelry or handled loose, have a natural tendency to draw oil and greasy dirt towards it and every time the diamond is handled by bare hands, it tends to pick up some grease from the hand. As we all know, grease attracts dust particles from the air and eventually there is a layer of grease and dust that covers the surface of the diamond. And we all know that when that takes place the light that reflects from the diamond is affected negatively.

The property of diamonds to attract grease has not always been seen as a negative property. In the earlier years, this property of diamonds was effectively used by diamond miners to separate diamonds from other minerals in the same ore. This was done by covering a belt in grease and wax and then allowing the crushed ore to run over the belt. As the crushed ore passed over the greasy belt, the uncut diamond rough would stick to the belt as the other minerals remained unaffected.

However, these processes have changed over time and there are more sophisticated methods that are now used to separate diamonds. But one thing is for sure, this unique property of diamonds continues to be the bane for those who handle and trade diamonds daily.

The scientific reason for why a diamond that is covered with a layer of grease and dust looses its sheen is due to the refractive index. The shine of the diamond is dependant on the light that enters the diamond and the manner in which it moves out of the diamond. When the light passes through a clean diamond the interface is between diamond and air. The refractive index of air is 1.0 but the refractive index of grease is 1.5.

In more practical terms what this means is that the diamond’s critical angle increases and the amount of light that reflects from the pavilion reduces significantly. The light does not go through the crown but falls inside and then some of it escapes out of the pavilion. And since the entire light that enters does not move in a focused manner but diffuses in the diamond, the shine, brilliance and glint of the diamond is far lesser than it could be.

Now, the customers who buy diamond jewelry do so because of its shine and luster and way it attracts attention too. Therefore, it is very important for one to keep the diamond jewelry shining.

Make sure that the diamonds are not handled unnecessarily except when they need to be. Keep the area where the diamond jewelry are displayed completelty clean and tidy. When you are handling the diamonds make sure that you hold it with tweezers, or wear gloves or use any lint/dust free cloth. After your customers handle the diamonds make sure that you wipe them with a soft, clean cloth before you replace them in their safe haven. As your diamonds dazzle your customers, you will realize that the cash registers ring more often and keep you smiling.

Here are a few effective tips to maintain your diamond Jewelry:-

Soak your diamond jewelry in some mild soap solution for half an hour avoiding contacts with each other as a diamond can scratch another diamond. Brush off dirt particles stuck in corners and wires with a soft brush. Rinse with clean water and dry with a clean cloth. Your precious pieces will appear as shining as they were before.

1. Never let your diamonds come in contact with chlorine bleach or other chemicals as these can pit or discolor the mountings.
2. Avoid wearing diamond jewelry while doing heavy household work. Though diamond is the hardest gemstone, yet it can be loosened by a certain activity and can also be chipped by a hard blow.
3. Try to store your diamond jewelry in dedicated jewel boxes wrapped in clean cotton or soft fabric clothes.
4. It is a good practice to get your diamond jewelry professionally cleaned and checked for loose prongs for added safety of your precious gemstones.

Just follow these simple tips and restore the brilliant colors and sparkling shine of your diamond jewelry.
