Chameleon - the Rarest colored Diamond

Diamond has a unique place in making its presence valuable among other gem stones with its best features of purity and clarity with elegance to depict its appearance. The precious gem has natural dazzling colors available in yellows, blues, greens, reds, oranges, pinks, browns and in fascinating black colors which carries its own value and fame over a long period of time.

The Chameleon diamonds

            ‘The chameleon diamonds’ are the most rarest of all the precious gem diamond available with exciting features of changing color with the exposure to a different kinds of light and temperature. The color change happens when moved from dark place to light focused one either be a natural or artificial light with a change of color from bright straw yellow to dark grayish-yellowish-green color. This chameleon diamond remains unchanged in grayish-yellowish-green color until it is in day light with out any prolonged darkness depending upon the environment. This unique diamond is faceted from natural diamond rough said mined from Australia.

Introduction of Chameleon Diamonds

            The first occurrence of chameleon diamonds were document reported at 1943 by ‘GIA diamond dictionary’. This rarest diamond is unique in features with special characteristics of color fluctuation which is impossible to be created in the laboratory. The famous Australia’s Argyle diamond mine having fame for fancy colored diamonds produces a Hydrogen rich diamond occasionally that exhibits ‘Chameleonlike’ color behavior in blue-violet-gray color or in gray-olive.

Identification procedures

            Chameleon diamonds are well proven by examination with steps of heating and observing with utmost care which may also cause changes with the permanent color of grayish-green if not found pure. Laboratory test is a well recommended deal to be checked under spectroscopic observation showing readings coupled with ultraviolet (UV) radiation reaction which effectively distinguishes the normal green gem stone from chameleon diamonds.

Diamond clarity grading

           

Diamonds are ranked with grades for quality in clarity and purity for its significance over the other existing valuable diamonds and gem stones. Grading measures are as follows for your reference…

Included (grades I1, I2 and I3): Diamonds are graded from I1 to I3 that describe about medium to large natural level of inclusions which are clear to unaided eye under normal light focus and are easy detectable.

Slightly Included (grades SI1, SI2 and SI3): Diamonds are graded from SI1 to SI3 describing the natural inclusion level to be less which is very difficult to be seen with normal eyes but detected with the magnification on around ten times into the diamonds.

Very slightly Included (grades VS1 and VS2): Diamonds graded with VS1 and VS2 are having very less natural inclusions which is impossible to view with unaided eyes and too difficult to view using ten times magnification.

Very, Very Slightly Included (grades VVS1 and VVS2): The diamond grades with VVS1 and VVS2 has very, very slight content of natural inclusion which is impossible to view under unaided eyes and very difficult for a skilled observer to view using ten times magnification.

Internally flawless (grade IF): Diamonds are described with grade IF which has no natural inclusions.
