We recommend a diamond of G-H color, SI2 clarity, and very good to excellent cut. There are more expensive diamonds, but diamonds of this quality will produce the same dazzling shower of light as those costing thousands of dollars more.

There are three simple reasons:

• First, it is the very good to excellent cut that breathes life and sparkle into a diamond.
• Second, most experts agree that a G-H color appears colorless when mounted, so spending more for D-E-F color diamonds isn’t necessary.
• Third, a diamond of SI2 clarity is "eye-clean", meaning it has no flaws visible to the naked eye.

The finest diamonds are colorless, rare and expensive. On the GIA grading scale below, D-F are considered colorless, G-I near colorless and any grade J or below shows an increasingly yellowish tinge. Beyond the preference for a whiter stone, however, the color of a diamond does not affect its brightness or sparkle.

Fast Fact: Most experts agree that, when mounted, diamonds in the "G-H" range appear colorless, and
represent a much better value than "D-F" stones which command significantly higher prices.

Diamonds with fewer flaws (inclusions) are rare and therefore more highly prized. In many cases, these flaws don’t detract from the beauty of the diamond because they are invisible to the naked eye.

Fast Fact: Any grade "SI2" or above has inclusions that are "eye clean", not visible to the naked eye.
Lower grade diamonds are noticeably more opaque or dark to the naked eye.

More than any other attribute, it is the Cut that makes a diamond brilliant and beautiful. A diamond that is
well cut reflects light internally and displays a dazzling shower of light back through the top of the stone.

Fast Fact: Diamonds from PlatinumOvernight are carefully inspected to meet the standards of very good to excellent cut. When viewing a diamond, look directly into the center: if there are dark facets in the center or a dark ring around the center, or if the diamond appears opaque, it is probably due to poor cut.

The secret of a diamond that is properly cut is that it returns a measurably greater amount of light, which is
displayed as brilliance, dispersion and scintillation. This is the true measure of a diamond's beauty.

	Brilliance: The total amount of white light, both external and internal, returned from the diamond to the eye of the observer.
	Dispersion: Flashes of color, or fire, particularly when viewing a diamond in strong, direct light.
	Scintillation: Reflections and flashes of white light from the diamond's surface as the diamond, observer or light source moves.
