Jewelers and precious stone and metal workers design, manufacture, and sell jewelry. They also adjust, repair, and appraise gems and jewelry.

Jewelers and precious stone and metal workers typically do the following:

• Examine and grade diamonds and other gems
• Create jewelry from gold, silver, and precious gemstones
• Shape metal to hold the gems when making individual pieces
• Make a model with carved wax (a mold) or with computers, and then make (cast) pieces with the model
• Solder pieces together and insert stones
• Smooth joints and rough spots and polish smoothed areas
• Inspect finished products to ensure proper gem spacing and metal shine
• Repair jewelry by replacing broken clasps, enlarging or reducing ring sizes, resetting stones, or soldering pieces together

New technology is helping to produce high-quality jewelry at a reduced cost and in less time. For example, lasers are often used for cutting and improving the quality of stones, for intricate engraving or design work, and for inscribing personal messages or identification on jewelry. Jewelers also use lasers to weld metals together with no seams or blemishes, improving the quality and appearance of jewelry.

Some manufacturing firms use computer-aided design and manufacturing (CAD/CAM) to make product design easier and to automate some steps. With CAD, jewelers can create a model of a piece of jewelry on the computer and then see the effect of changing different aspects--the design, the stone, the setting--before cutting a stone or taking other costly steps. With CAM, they then create a mold of the piece, which makes producing many copies easy.

Individual jewelers also use CAD software to design custom jewelry. They let the customer review the design on the computer and see the effect of changes so the customer is satisfied before committing to the expense of a customized piece of jewelry.

Jewelers and precious stone and metal workers usually specialize:

Precious metal workers expertly manipulate gold, silver, and other metals.

Gemologists analyze, describe, and certify the quality and characteristics of gem stones. After using microscopes, computerized tools, and other grading instruments to examine gem stones or finished pieces of jewelry, they write reports certifying that the items are of a particular quality.

Jewelry appraisers carefully examine jewelry to determine its value and then write appraisal documents. They determine value by researching the jewelry market and by using reference books, auction catalogs, price lists, and the Internet. They may work for jewelry stores, appraisal firms, auction houses, pawnbrokers, or insurance companies. Many gemologists also become appraisers.

Bench jewelers usually work for jewelry retailers, doing tasks from simple jewelry cleaning and repair to making molds and pieces from scratch.

Curators oversee collections, such as artwork and historic items, and may conduct public service activities for an institution. Museum technicians and conservators prepare and restore objects and documents in museum collections and exhibits.

Curators, museum technicians, and conservators typically do the following:

• Acquire, store, and exhibit collections
• Select the theme and design of exhibits
• Develop or set up exhibit materials
• Design, organize, or conduct tours and workshops for the public
• Attend meetings and civic events to promote the institution
• Clean objects using cleansers, solvents, and soap solutions
• Direct and supervise curatorial, technical, and student staff
• Plan and conduct special research projects

Many objects and documents are important or historically significant. Curators, museum technicians, and conservators preserve and organize the display of these materials.

The following are occupational specialties:

Curators manage museums, zoos, aquariums, botanical gardens, nature centers, and historic sites. The museum director often is a curator. Curators direct the acquisition, storage, and exhibit of collections, including negotiating and authorizing the purchase, sale, exchange, or loan of collections. They also may authenticate, evaluate, and categorize the specimens in a collection.

Curators often oversee and help conduct the institution's research projects and related educational programs.

Today, an increasing part of a curator's duties involves fundraising and promotion, which may include writing and reviewing grant proposals, journal articles, and publicity materials. In addition, many curators attend meetings, conventions, and civic events.

Most curators specialize in a particular field, such as botany, art, or history. Those who work in large institutions may be highly specialized. A large natural history museum, for example, might employ separate curators for its collections of birds, fishes, insects, and mammals.

Some curators take care of their collections, some do research related to items in the collection, and others do administrative tasks. In small institutions with only one or a few curators, one curator may be responsible for a number of tasks, from taking care of collections to directing the affairs of the museum.

Museum technicians, commonly known as registrars, help curators by preparing and taking care of museum items. Registrars also may answer questions from the public and help curators and outside scholars use the collections.

Conservators manage, preserve, treat, and document works of art, artifacts, and specimens--work that may require substantial historical, scientific, and archaeological research. Conservators document their findings and treat items to minimize their deterioration or to restore them to their original state.

Conservators usually specialize in a particular material or group of objects, such as documents and books, paintings, decorative arts, textiles, metals, or architectural material. They use x rays, chemical testing, microscopes, special lights, and other laboratory equipment and techniques to examine objects, determine their condition, and decide on the best way to preserve them.

In addition to their conservation work, conservators participate in outreach programs, research topics in their specialty, and write articles for scholarly journals. They may be employed by a museum or other institution that has objects needing conservation, or they may be self-employed and have several clients.

Archivists appraise, edit, and maintain permanent records and historically valuable documents. Many perform research on archival material.

Archivists typically do the following:

• Create and maintain accessible computer archives and databases
• Organize and classify archival records to make it easy to find materials
• Authenticate and appraise historical documents and archival materials
• Provide reference services and help for users
• Direct workers who help arrange, exhibit, and maintain collections
• Safeguard records by copying to film, videotape, disk, or computer formats
• Preserve and maintain documents and objects
• Set and administer policy guidelines concerning public access to materials
• Locate new materials and direct their acquisition and display

Archivists preserve many documents and records for their importance, potential value, or historical significance. Most archivists coordinate educational and public outreach programs, such as tours, workshops, lectures, and classes. Some work with the boards of institutions to administer plans and policies. In addition, archivists may research topics or items relevant to their collections.

Some archivists specialize in an area of history, such as colonial history, so they can more accurately determine which records in that area should be kept and should become part of the archives. Archivists also may work with specialized forms of records, such as manuscripts, electronic records, websites, photographs, maps, motion pictures, or sound recordings.

Archivists usually use computers to generate and maintain archival records. Professional standards for handling electronic archival records are still evolving. However, computer capabilities will continue to expand and more records will be stored and exhibited electronically, providing both increased access and better protection for archived documents.

Archives technicians help archivists organize, maintain, and provide access to historical documentary materials.

Cost estimators collect and analyze data to estimate the time, money, resources, and labor required for product manufacturing, construction projects, or services. Some specialize in a particular industry or product type.

Cost estimators typically do the following:

• Consult with industry experts to discuss estimates and resolve issues
• Identify and quantify cost factors, such as production time and raw material, equipment, and labor expenses
• Travel to job sites to gather information on materials needed, labor requirements, and other factors 
• Read blueprints and technical documents to prepare estimates
• Collaborate with engineers, architects, owners, and contractors on estimates
• Use sophisticated computer software to calculate estimates 
• Evaluate a product's cost effectiveness or profitability
• Recommend ways to make a product more cost effective or profitable
• Prepare estimates for clients and other business managers
• Develop project plans for the duration of the project

Accurately predicting the cost, size, and duration of future construction and manufacturing projects is vital to the survival of any business. Cost estimators' calculations give managers or investors this information.

When making calculations, estimators analyze many inputs to determine how much time, money, and labor a project needs, or how profitable it will be. These estimates have to take many factors into account, including allowances for wasted material, bad weather, shipping delays, and other factors that can increase costs and lower profitability.

Cost estimators use sophisticated computer software, including database, simulation, and complex mathematical programs. Cost estimators often use a computer database with information on the costs of other similar projects.

General contractors usually hire cost estimators for specific parts of a large construction project, such as estimating the electrical work or the excavation phase. In such cases, the estimator calculates the cost of the construction phase for which the contractor is responsible, rather than calculating the cost of the entire project. The general contractor usually also has a cost estimator who calculates the total project cost by analyzing the bids that the subcontractors' cost estimators prepared.

Some estimators are hired by manufacturers to analyze certain products or processes.

The following are the two primary types of cost estimators:

Construction cost estimators estimate construction work. More than half of all cost estimators work in the construction industry. They may, for example, estimate the total cost of building a bridge or a highway. They may identify direct costs, such as raw materials and labor requirements, and set a timeline for the project. Although many work directly for construction firms, some work for contractors, architects, and engineering firms.

Manufacturing cost estimators calculate the costs of developing, producing, or redesigning a company's goods and services. For example, a cost estimator working for a home appliance manufacturer may determine whether a new type of dishwasher will be profitable to manufacture.

Some manufacturing cost estimators work in software development. Many high-technology products require a considerable amount of computer programming, and the costs of software development are difficult to calculate.  

Two other groups also sometimes do cost estimating in their jobs. Operations research, production control, cost, and price analysts who work for government agencies may do significant amounts of cost estimating in the course of their usual duties. Construction managers also may spend considerable time estimating costs. For more information, see the profiles on operations research analysts and construction managers.

Craft and fine artists use a variety of materials and techniques to create art for sale and exhibition. Craft artists create handmade objects, such as pottery, glassware, textiles or other objects that are designed to be functional. Fine artists, including painters, sculptors, and illustrators, create original works of art for their aesthetic value, rather than a functional one.

Craft and fine artists typically do the following:

• Use techniques such as knitting, weaving, glass blowing, painting, drawing, or sculpting
• Develop creative ideas or new methods for making art
• Create sketches, templates, or models to guide their work
• Select which materials to use on the basis of color, texture, strength, and other qualities
• Process materials, often by shaping, joining, or cutting
• Use visual elements, such as composition, color, space, and perspective, to produce desired artistic effects
• Develop portfolios highlighting their artistic styles and abilities to show to gallery owners and others interested in their work

Artists create objects that are beautiful or thought-provoking. They often strive to communicate ideas or feelings through their art.

Craft artists make a wide variety of objects, mostly by hand, to sell in their own studios, online, in stores, or at arts-and-crafts shows. Some craft artists display their works in galleries and museums.

Craft artists work with many different materials, including ceramics, glass, textiles, wood, metal, and paper, to create unique pieces of art, such as pottery, quilts, stained glass, furniture, jewelry, and clothing. Many craft artists also use fine-art techniques--for example, painting, sketching, and printing--to add finishing touches to their products.

Fine artists typically display their work in museums, commercial or non-profit art galleries, corporate collections, and private homes. Some of their artwork may be commissioned (requested by a client), but most is sold by the artist or through private art galleries or dealers. The gallery and the artist decide in advance how much of the sale proceeds each will keep.

Some craft and fine artists spend much time and effort selling their artwork to potential customers or clients and building a reputation. However, only the most successful artists are able to support themselves solely through the sale of their works. Many artists have at least one other job to support their craft or art careers.

Some artists work in museums or art galleries as arts directors or as curators, planning and setting up exhibits. Others teach craft or art classes or conduct workshops in schools or in their own studios. For more information on workers who teach art classes, see the profiles on kindergarten and elementary school teachers, middle school teachers, high school teachers, postsecondary teachers, and self-enrichment teachers.

Craft and fine artists specialize in one or more types of art. The following are examples of types of craft and fine artists:

Cartoonists draw political, advertising, comic, and sports cartoons. Some cartoonists work with others who create the idea or story and write captions. Some create plots and write captions themselves. Most cartoonists have comic, critical, or dramatic talents in addition to drawing skills.

Ceramic artists shape, form, and mold artworks out of clay, often using a potter's wheel and other tools. They glaze and fire pieces in kilns, which are special furnaces that dry and harden the clay.

Fiber artists use fabric, yarn, or other natural and synthetic fibers to weave, knit, crochet, or sew textile art. They may use a loom to weave fabric, needles to knit or crochet yarn, or a sewing machine to join pieces of fabric for quilts or other handicrafts.

Fine art painters paint landscapes, portraits, and other subjects in a variety of styles, ranging from realistic to abstract. They may use one or more media, such as watercolors, oil paints, or acrylics.

Furniture makers cut, sand, join, and finish wood and other materials to make handcrafted furniture. For more information about other workers who assemble wood furniture, see the profile on woodworkers.

Glass artists process glass in a variety of ways--such as by blowing, shaping, or joining it--to create artistic pieces. Specific processes used include glassblowing, lampworking, and stained glass. These workers also decorate glass objects, such as by etching or painting.

Illustrators create pictures for books, magazines, and other publications, and for commercial products, such as textiles, wrapping paper, stationery, greeting cards, and calendars. Increasingly, illustrators use computers in their work. They might draw in pen and pencil and then scan the image into a computer to be colored in, or use a special pen to draw images directly onto the computer.

Sketch artists, a particular type of illustrator, often create likenesses of subjects with pencil, charcoal, or pastels. Sketches are used by law enforcement agencies to help identify suspects, by the news media to show courtroom scenes, and by individual customers for their own enjoyment.

Jewelry artists use metals, stones, beads, and other materials to make objects for personal adornment, such as earrings or bracelets. For more information about other workers who create jewelry, see the profile on jewelers and precious stone and metal workers.

Medical and scientific illustrators combine drawing skills with knowledge of biology or other sciences. Medical illustrators work with computers or with pen and paper to create images of human anatomy and surgical procedures, as well as three-dimensional models and animations. Scientific illustrators draw animal and plant life, atomic and molecular structures, and geologic and planetary formations. These illustrations are used in medical and scientific publications and in audiovisual presentations for teaching purposes. Some medical and scientific illustrators work for lawyers, producing exhibits for court cases.

Printmakers create images on a silk screen, woodblock, lithography stone, metal etching plate, or other type of matrix. The matrix is then inked and transferred to a piece of paper using a printing press or hand press to create the final work of art. Workers who do photoengraving are called printing workers. For more information, see the profile on printing workers.

Sculptors design three-dimensional works of art, either by molding and joining materials such as clay, glass, plastic, or metal, or by cutting and carving forms from a block of plaster, wood, or stone. Some sculptors combine various materials to create mixed-media installations. For example, some incorporate light, sound, and motion into their works.
