Beauty of Gems
Although it is not one of the 4 Cs, cleanliness affects a diamond's beauty as much as any of the 4 C's (cut, carat, colour, clarity).
A clean diamond is more brilliant and fiery than the same diamond when it is "dirty". Dirt or grease on the top of a diamond reduces its lustre. Water, dirt, or grease on the bottom of a diamond interferes with the diamond's brilliance and fire. Even a thin film absorbs some light that could have been reflected to the person looking at the diamond.
Coloured dye or smudges can affect the perceived colour of a gem. Historically, some jewellers' diamonds were misgraded due to smudges on the girdle, or dye on the culet. Current practice is to thoroughly clean a gem before grading its colour as well as clarity.
Cleanliness does not affect the jewellery's market value, as jewellers routinely clean jewellery before offering it for sale. However, cleanliness might reflect the jewellery's sentimental value.

Famous quotes containing the words beauty of, beauty and/or gems:
“Man, she looked as though she’d been thrown off the crummiest freight train in the world. Yet, in spite of this, I got the impression of beauty. Not the beauty of a movie actress, mind you, or the beauty you dream about when you’re with your wife. But a natural beauty. A beauty that’s almost homely because it’s so real.”
—Martin Goldsmith, and Edgar G. Ulmer. Al Roberts (Tom Neal)
“Things thought too long can be no longer thought
For beauty dies of beauty, worth of worth,
And ancient lineaments are blotted out.”
—William Butler Yeats (1865–1939)
“Rich and rare were the gems she wore,
And a bright gold ring on her hand she bore.”
—Thomas Moore (1779–1852)
