Methods and risks
Maintaining a clean diamond can sometimes be difficult, as jewelry settings can obstruct cleaning efforts, and oils, grease, and other hydrophobic materials adhere well to a diamond's surface. Some jewellers provide their customers with sudsy ammonia cleaning kits. Some other jewellers sell small ultrasonic cleaners. Home-based cleaning methods include immersing the diamond in ammonia-based or ethyl alcohol-based solutions, or even a solution of mild grease dissolving detergent and warm water. In chemistry, hydrophobic or lipophilic species, or hydrophobes, tend to be electrically neutral and nonpolar, and thus prefer other neutral and nonpolar solvents or molecular environments. ...
Ammonia is a compound of nitrogen and hydrogen with the formula NH3. ...
Ethyl alcohol, also known as ethanol or grain alcohol, is a flammable, colorless chemical compound, one of the alcohols that is most often found in alcoholic beverages. ...
A detergent is a compound, or a mixture of compounds, intended to assist cleaning. ...
Cleaning can damage some jewelry. For example, some class rings are coated with a dark pigment to reduce their shininess. Ultrasonic cleaning can remove this coating. Also, many gems (such as emerald and pearl) are soft or porous. Cleaning agents can erode or infiltrate these gems. Ultrasonic cleaning is also contraindicated for Opals, Tanzanite, Amber, and any gemstone that reveals a high degree of internal fractures. For other things of this name, see Emerald (disambiguation). ...

Beauty of gems Although it is not one of the 4 C's, cleanliness affects a diamond's beauty as much as any of the 4 C's (cut, carat, color, clarity). A scattering of round-brilliant cut diamonds shows off the many reflecting facets. ...
This article addresses the many styles of diamond cut. ...
Meanings of Carat or Karat: Carat is a unit of mass for gems. ...
Jewelers set diamonds in groups of similar colors. ...
Diamond clarity is a quality of diamonds relating to the existence and visual appearance of internal defects of a diamond called inclusions, and surface defects called blemishes. ...
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 luster. 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.
Colored dye or smudges can affect the perceived color 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 color as well as clarity.
Cleanliness does not affect the jewelry's market value, as jewellers routinely clean jewelry before offering it for sale. However, cleanliness might reflect the jewelry's sentimental value: some jewellers have noted a correlation between ring cleanliness and marriage quality.
