Creation of artificial diamonds require enormous pressures and high temperatures and to this point in time have only been moderately successful in Russia, Ireland and South Africa making industrial quality stones, not gemstones. Opal jewelry is also rumored to aid in obtaining clarity. Colors of Opal Jewelry The truly unique thing about opal is that it displays all the colors of the color spectrum in a so-called play of color, that results from the diffraction of light when passing through the tiny silica spheres that exist deep within the infrastructure of the opal.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Ideal cut refers to the angles and proportions of a diamond that satisfy very precise mathematical formulas. The result is that the the ideal cut diamond internally reflects most light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire, thereby placing ideal-cut diamonds higher on the quality pyramid than deep or shallow-cut diamonds.
Color An E color diamond is extremely rare and slightly less expensive than a D but is so similar that most people won’t be able to tell the difference. You pay a serious premium for an E color diamond. Diamonds of this color grade will appear colorless even when observed face down.

Good color SI2 clarity diamonds are an attractive choice when working within a fixed budget without sacrificing beauty or value. These diamonds balance good clarity with exceptional price.
