WHAT IS A NATURAL DIAMOND

brilliant diamondsThe natural diamond is pure native crystalized carbon formed under very high temperatures and pressures. These conditions occur in limited zones of earth's mantle about 90 miles under the earth surface. Diamonds formed (up to 3,9 billion years ago) and stored in these "diamond stability zones" are delivered to earth's surface during deep-source volcanic eruptions. During this long formations, natural inclusions or flaws could appear in the diamond. Most of these inclusions will never appear in synthetic diamonds, which are machinery made.

HOW TO TAKE CARE OF DIAMONDS

Even if diamonds are the hardest material on earth, be careful for intensive shocks, because the diamond could crack. This has nothing to do with the setting of your diamond in the jewellery, but with the tension in the diamond.

HOW TO CLEAN DIAMONDS

Never clean your diamond jewellery in boiling water. The jewellery will sink to the bottom, which is always hotter than the 100° C boiling water.

HOW TO CLEAN DIAMOND JEWELLERY

(only with open diamond settings)

Take a soft toothbrush with some soft detergent, clean the jewellery under lukewarm water en rinse it carefully. Never use abrasive detergent or a hard toothbrush, it could damage the other gemstones of the jewellery.

HOW TO CLEAN DIAMOND JEWELLERY

(with closed diamond settings)

Be careful to use water, because some diamond settings from the past (from the 18th and 19th century) with rose cut diamonds were backed with a silver foil. By cleaning this jewellery with water, it could damage the diamond setting and the diamond brilliance. Ask advice to your jeweller.

HOW COULD NATURAL DIAMONDS BE DEFINED

Natural diamonds could be defined in 2 major categories: the TYPE I(a & b) and Type II(a & b). Most of natural diamonds are diamonds from Type I, while Type II natural diamonds are extremely rare.

About diamond evaluation - 4 C

The diamond is evaluated by the 4 C: CARAT, CLARITY, COLOUR and CUT. These 4 C will determine the value of the diamond. Rarely two diamonds are exactly the same.

MORE INFO ABOUT THE CARAT

The carat or the weight of a diamond is one of the measurements to evaluate the diamond. One carat is equal to 0,02 gram. A diamond of 5 carats weights 1 gram. One carat could also be divided into 100 points. A diamond from 50 points weights 0.50 carat or half a carat. Be careful, because two diamonds can be of equal carat-weight, but their value can be different mainly due to the cut, colour or clarity. The weight is very easy to measure.

MORE INFO ABOUT THE CLARITY

The clarity of diamonds is determined by the amount and location of inclusions or imperfections in the diamond when viewed with a loupe (magnification x 10). The clarity grades in diamonds are set by standards from Flawless to Imperfect 3 standards. The fewer the inclusions, the more beautiful and valuable the diamond will be. And if there are inclusions, the position of an inclusion in the diamond is important to evaluate the clarity of the diamond. 

MORE INFO ABOUT THE COLOUR

Diamonds exist naturally in every colour. But most people are concerned with diamonds in the white range. The best colour for the white range is colourless without a tint of yellow. So the range goes from D (colourless) to Z (light yellow). These Standards evaluate the range of colour and thus its value.

MORE INFO ABOUT THE CUT

One of the C is the cut or the proportion of the shaped diamond. An excellent cut is when the maximum amount of light that enters through its top will be reflected and dispersed back through its top. Standards are set to evaluate the quality of the cut and determine its value.

DID YOU KNOW...

Even if white diamonds have been seen as one of the most precious gemstones on earth. Other collectors’ gems are also very valuable. Have you ever heard about Red Beryl, Alexandrite, Tanzanite, Musgravite or Fancy coloured diamonds?

DID YOU KNOW...

Only 20 % of all mined - thus natural - diamonds are qualified as gem-quality. This means that only a little fraction of all mined diamonds are used in jewellery. This instead of synthetic diamonds which are made by machinery and where production could increase rapidly in the upcoming years.

DID YOU KNOW...

Even if a diamond is one of the hardest materials on earth, it could crack due to an intensive shock. The physical and chemical structure of diamonds are often characterised by a high tension inside the gemstone and is thus fragile for shocks.

DID YOU KNOW

That natural diamonds from type II are extremely rare on earth, but very common as synthetic diamonds. These diamonds doesn't have (a lot of) nitrogen in their composition.
