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:
“Men nowhere, east or west, live yet a natural life, round which the vine clings, and which the elm willingly shadows. Man would desecrate it by his touch, and so the beauty of the world remains veiled to him. He needs not only to be spiritualized, but naturalized, on the soil of earth.”
—Henry David Thoreau (1817–1862)
“Poetry lifts the veil from the hidden beauty of the world, and makes familiar objects be as if they were not familiar.”
—Percy Bysshe Shelley (1792–1822)
“Too often when you thought you’d be showered with confetti
What they flung at you was a plate of hot spaghetti
You’ve put your fancy clothes and flashy gems in hock
Yet you pause before your father’s door afraid to knock”
—John Ashbery (b. 1927)
