How to cleaning your jewelry?

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 jewelers provide their customers with sudsy ammonia cleaning kits. Many jewelers use steam cleaners. Some other jewelers 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. Silver jewelry can be cleaned using aluminum foil, baking soda, and hot water. However, this practice is not recommended by most jewelers.
Certain types of cleaning can damage some jewelry. For example, some class rings are coated with a dark pigment to reduce their shininess. Some gemstones, such as white topaz, have an overlay to produce certain colors. Ultrasonic cleaning can remove this coating, if it is not a quality piece. Ultrasonic cleaning is also contraindicated for opals, pearls and amber, and any other gemstone that is porous. Gemstones that are glued in (a common practice with semiprecious stones in non-precious methods, and in class rings) should not be placed into an ultrasonic cleaner. An ultrasonic cleaner can cause stones that are loose in their settings to come out. Jewelry should always be examined for overlays and loose stones prior to cleaning with an ultrasonic cleaner or a steam cleaner.

Jewelry Care

There are a number of things you can do to prevent build up of dirt and prevent jeweler becoming tarnished. Namely: Store jeweler carefully in its original packaging or a jeweler’s box. Clean jeweler using warm water, mild soap and a soft bristle toothbrush. Use a non abrasive silver cloth or soft lint free cloth to polish jeweler and remove tarnishing. Don't expose jeweler to harsh chemicals or perfumes as this could cause damage and discoloration. Don't wear jewelers when doing anything heavy duty and avoid unnecessary knocks and scratches.

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 jewelers' diamonds were migrated 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 jeweler’s market value, as jeweler’s routinely clean jeweler before offering it for sale. However, cleanliness might reflect the jeweler’s sentimental value.

Garnet - The Nightmare Protector - January

GarnetsGarnet is the accepted birthstone for the month of January. It is also the accepted anniversary gemstone for the second year of marriage. When most people think of garnet, they picture the dark red bohemian garnet that was popular in Victorian times. You may be surprised to learn that garnets are found in every color except blue, including brilliant green tsavorite garnet, raspberry pink rhodolite garnet, and orange malaya garnet. Bright red "anthill" garnets are found in Arizona. The Tzars of Russia favored rare green damantoid garnets. Garnets offer enough variety in appearance to suit every taste, as well as an outstanding price range to suit every pocketbook. Legend holds that Noah hung a large garnet in the ark for illumination. It reportedly also gives its wearer guidance in the night, protection from nightmares, and according to the Egyptians, is an antidote for snake bites and food poisoning. It was also thought to have a special affinity with the blood. Garnets are durable and brilliant and will give years of pleasure. As with all gemstones, care should be taken to protect it from scratches, sharp blows, and extreme temperature changes. Garnets are found in the U.S., Africa, Sri Lanka, Brazil and India.
