Many white sapphires are crafted to resemble diamonds, but the fact remains that they are two distinct gemstones. If one knows where to look and what to look for, he/she can instantly tell the difference between the two. Which brings us to the conclusion of our story - Miss Y found out that Mr. X had cheated her of the diamond ring, and stormed away in anger, leaving Mr. X to ponder over his misdoing!
Fluorescence: It creates a major coloring effect, positive or negative, in presence of light. Virtually all exhibit this property in the presence of X-rays or UV rays. This characteristic also helps in identification of diamonds. Fluorescence if strong, may alter the perceived color of the given diamond positively or negatively. Hence, the gemstone which has no effect with fluorescence is rated higher.
Although, a structurally perfect and chemically pure diamond can be defined as the one with complete transparent appearance with no hue or color, in reality no such gem size diamond can be found. The lack of color contributes towards higher grading. Hue is one of the main attribute of perceived color, besides lightness and chroma. The color is generally affected by few structural defects in its crystal lattice. Chemical impurities also contribute towards deviation of color from perfect white.
World Diamond Council imposed a complete restrain upon trade in conflict diamonds in January, 2001. During the same time, the Kimberley Process Certification Scheme (KPCS) was given shape in order to impose stringent regulations on the export and import of diamonds and to introduce a legislation all over the world compelling every country to accept only those packages of diamond that are officially sealed.
