Methods and risks

Some kinds of jewelry can be cleaned at home while others are suggested to be done by a professional. Jewelry made from gold and sterling silver are examples of jewelry that can be cleaned at home, while platinum should not be due to how at-risk platinum is of scratching. Jewelry with gemstones such as diamonds or sapphires can be cleaned at home as well using mild soap and warm water. However, gemstones such as opals and pearls should be done professionally. Another issue is the age of jewelry, as certain materials or build strategies of older jewelry (such as from the Georgian era) may have restrictions, such as not being able to get wet without damage. Keeping your jewelry clean helps to ensure that the gemstone(s) keep a good appearance and prevents dirt and grease (among others) from loosening them. Dirty jewelry may also cause skin irritation. [1]

A professional cleaning may take anywhere from a few minutes to a few days depending on the circumstances. The cleaner would first inspect the jewelry to ensure that the gemstones are accounted for and secured. Materials that can handle it are often placed in an ultrasonic bath using a cleaning solution and later put through a steam cleaner, while more sensitive materials will go through light brushing in soapy water. Following this, they are rinsed, dried, and inspected. [1] A jeweler may provide their customers with sudsy ammonia cleaning kits, while another may sell small ultrasonic cleaners.[ citation needed ] Some gemstones, such as white topaz, have an overlay to produce certain colors. Ultrasonic cleaning can remove this coating. [2]

Ultrasonic cleaners are useful for jewelry cleaning and removing tarnish. They use ultrasound waves and chemicals combined to create bubbles that "cling" to the foreign particles such as dirt, oil, and unknown substances. The high frequency waves are sent out and pull the contaminants off the object. The bubbles collapse after they attach to the contaminants and move to the surface of the chemical solution creating what appears to be a boiling solution. [3]

Cleanliness of gems

Colored dye or smudges can affect the perceived color of a gem.[ citation needed ] Historically, some jewelers' diamonds were mis-graded due to smudges on the girdle, or dye on the culet.[ citation needed ] Current practice is to thoroughly clean a gem before grading its color as well as clarity.[ citation needed ]

How a gem can be safely cleaned depends upon its individual characteristics and therefore its susceptibility to damage. [4]

Amethyst is a violet variety of quartz. The name comes from the Koine Greek αμέθυστος amethystos from α-a-, "not" and μεθύσκωmethysko / μεθώmetho, "intoxicate", a reference to the belief that the stone protected its owner from drunkenness. Ancient Greeks wore amethyst and carved drinking vessels from it in the belief that it would prevent intoxification.

<span class="mw-page-title-main">Gemstone</span> Piece of mineral crystal used to make jewelry

A gemstone is a piece of mineral crystal which, when cut or polished, is used to make jewelry or other adornments. Certain rocks and occasionally organic materials that are not minerals may also be used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some softer minerals such as brazilianite may be used in jewelry because of their color or luster or other physical properties that have aesthetic value. However, generally speaking, soft minerals are not typically used as gemstones by virtue of their brittleness and lack of durability.

Lapidary is the practice of shaping stone, minerals, or gemstones into decorative items such as cabochons, engraved gems, and faceted designs. A person who practices lapidary is known as a lapidarist. A lapidarist uses the lapidary techniques of cutting, grinding, and polishing. Hardstone carving requires specialized carving techniques.

<span class="mw-page-title-main">Cleaning</span> Activity that removes dirt and other particles from people, animals and objects

Cleaning is the process of removing unwanted substances, such as dirt, infectious agents, and other impurities, from an object or environment. Cleaning is often performed for aesthetic, hygienic, functional, safety, or environmental protection purposes. Cleaning occurs in many different contexts, and uses many different methods. Several occupations are devoted to cleaning.

Housekeeping is the management and routine support activities of running and maintaining an organized physical institution occupied or used by people, like a house, ship, hospital or factory, such as cleaning, tidying/organizing, cooking, shopping, and bill payment. These tasks may be performed by members of the household, or by persons hired for the purpose. This is a more broad role than a cleaner, who is focused only on the cleaning aspect. The term is also used to refer to the money allocated for such use. By extension, it may also refer to an office or a corporation, as well as the maintenance of computer storage systems.

<span class="mw-page-title-main">Stain</span> A discoloration that can be clearly distinguished from the surface

A stain is a discoloration that can be clearly distinguished from the surface, material, or medium it is found upon. They are caused by the chemical or physical interaction of two dissimilar materials. Accidental staining may make materials appear used, degraded or permanently unclean. Intentional staining is used in biochemical research and for artistic effect, such as wood staining, rust staining and stained glass.

<span class="mw-page-title-main">Tension ring</span>

A tension ring is a type of finger ring that holds a gemstone in place by pressure rather than prongs, a bezel or other mounting. The metal setting is actually spring-loaded to exert pressure onto the gemstone, and tiny etchings or grooves in the metal create a shelf that supports the gemstone's edges. The gemstone appears to be suspended in the air with nothing holding it in place.

<span class="mw-page-title-main">Parts cleaning</span>

Parts cleaning is a step in various industrial processes, either as preparation for surface finishing or to safeguard delicate components. One such process, electroplating, is particularly sensitive to part cleanliness, as even thin layers of oil can hinder coating adhesion.

<span class="mw-page-title-main">Prong setting</span>

Prong setting or prong mount refers to the use of metal projections or tines, called "prongs", to secure a gemstone to a piece of jewelry. A prong setting is one component of what is known to jewelers as a head, a claw-shaped type of binding that is welded or soldered to a jewelry item to mount a gemstone to the jewelry item. A common setting for diamond engagement rings, the prong setting allows light to strike a gemstone from more angles, increasing its brilliance.

Cleaning agents or hard-surface cleaners are substances used to remove dirt, including dust, stains, foul odors, and clutter on surfaces. Purposes of cleaning agents include health, beauty, removing offensive odor, and avoiding the spread of dirt and contaminants to oneself and others. Some cleaning agents can kill bacteria and clean at the same time. Others, called degreasers, contain organic solvents to help dissolve oils and fats.

<span class="mw-page-title-main">Ammolite</span> Opal-like organic gemstone

Ammolite is an opal-like organic gemstone found primarily along the eastern slopes of the Rocky Mountains of North America. It is made of the fossilized shells of ammonites, which in turn are composed primarily of aragonite, the same mineral contained in nacre, with a microstructure inherited from the shell. It is one of few biogenic gemstones; others include amber and pearl. In 1981, ammolite was given official gemstone status by the World Jewellery Confederation (CIBJO), the same year commercial mining of ammolite began. It was designated the official gemstone of Lethbridge, Alberta, Canada in 2007, and was subsequently designated as Alberta's official gemstone in April 2022.

<span class="mw-page-title-main">Gemstone irradiation</span> Process to enhance a gemstones optical properties

Gemstone irradiation is a process in which a gemstone is artificially irradiated in order to enhance its optical properties. High levels of ionizing radiation can change the atomic structure of the gemstone's crystal lattice, which in turn alters the optical properties within it. As a result, the gem­stone's color may be significantly altered or the visibility of its inclusions may be lessened.
