Sound of jewellery
The Sound of jewellery has played an enermous part in many stories, poems, and religious literature (more details and sources to come). Different jewellery creates different sounds, ie plastic bangles create a high pitched clink sound, while others such as baxelite produce a "clunck" sound. Knowing how a particular piece of jewellery sounds can help someone identify whether or not a piece of jewellery is fake. Indeed people have written about the sound of "fake gold", and jewel makers such as Sharon Alouf, a famous jeweler have praised the high frequency pitched noise of gold bangles(most likely real gold she is wearing). To this day, the jeweler claims, "the sound of bangles clinking together is very soothing to me. It always reminds me of motherhood."Alouf is even partial to particular tones. "Gold produces my favorite sound," she says, "the pitch is higher and clearer, which I find energizing."
Jewellery cleaning
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.

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. Examination prior to cleaning is a good practice as ultrasonic cleaning is an aggressive method
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 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.
