In one sentence, describe what the following article is about: A stone with a rough or sandy texture should not be identified as a gemstone. A stone that is readily malleable—i.e. easy to shape by hammering, crushing, or bending it—the stone is more likely a metallic ore than an actual gemstone.  True gemstones have a crystalline structure. This structure can be shaped through cutting, fracturing, and abrasion, but it has fixed planes that cannot be altered by pressure alone.  Don't hit a stone with a hammer if you don't want to shatter it. Real gemstones don't get bend or reshaped, but they do break. In particular, pearls and fossilized wood can be mistakenly classified as gemstones but do not fit the qualifications in the strictest sense of the term. Synthetic stones share the same structure, chemical composition, and physical properties of their natural counterparts, but they are created in a lab rather than made naturally. You can usually spot a synthetic by observing several characteristics.  Synthetic stones often have curved growth patterns inside the stone rather than angular growth patterns.  Gas bubbles are that are round and come in large strings are often an indication, but be careful, since a gas bubble in an inclusion can occur within natural stones. Platinum or gold platelets can stick to synthetic stones. Fingerprint-patterned inclusions are common in synthetics, as are nail-shaped inclusions, chevron (v-shaped) growth patterns, wispy veil-like inclusions, and interior columnar structures. An imitation stone is a material that looks like a real gemstone upon first glance in spite of the fact that it is made of a completely different material. These stones can be natural or artificial, but there are a few good techniques used to spot them either way. Pay a special attention while checking Turquoise, Lapis, Sapphire, Ruby and Emerald because there are many treatments available in market which make the stones same like natural  The surface of an imitation may look pitted and uneven, like an orange peel. Some imitations have swirl marks known as "flow lines." Large, round gas bubbles are common within imitations.  Imitations tend to feel lighter than their natural counterparts. Assembled stones are made of two or more materials. These stones may consist entirely of natural gems, but oftentimes, synthetic materials are mixed in.  Use a penlight to illuminate the stone when checking for signs of assembly. Look for differences in luster or for colored and colorless cement. Also look for the "red ring effect." Turn the stone face down and look for a red ring along the outer part of the stone. If you spot the red ring, you probably have an assembled stone.
Summary: Feel the stone's surface. Check its malleability. Know which materials are not classified as gemstones. Watch out for synthetics. Watch out for imitations. Determine whether or not the gemstone is an assembled stone.

The secret to a close shave and shiny, glowing legs is exfoliating before you shave. Exfoliation will remove dead skin cells that could otherwise clog up your razor. A razor clogged with dead skin cells will prevent you from getting a close shave. Use a firm, natural-bristle brush. Begin by brushing the outside of your knee. Brush upwards, applying enough pressure to stimulate circulation. Continue by brushing the inside of the thigh. Then brush the calf, beginning at the foot and brushing toward the groin. Finish by brushing your buttocks from the middle out toward your hip. While you want to apply pressure, you should not press so hard that it hurts. Exfoliating gloves are a great, chemical-free way to exfoliate your legs. You can use them while you are in the shower, and don't need any special products. Simply get into a warm shower, allow your skin to hydrate in the steam and water for at least two minutes, and rub your legs with the gloves. Physical exfoliants that use salt, coffee grinds, sand, or other harsh ingredients leave tiny cuts on your skin. This is undesirable before a shave, as shaving already puts your delicate skin at risk for nicks and cuts.

One-sentence summary -- Exfoliate your legs before you shave. Try dry brushing. Use exfoliating gloves in the shower. Avoid sand, salt or coffee based exfoliants.

Problem: Article: You may not be interested in volunteering or attaining a job—that's okay. Helping out others is only a recommendation. However, many volunteers report that their work makes them feel good; some volunteer work can even help with self-development.  Consider the benefits and drawbacks of volunteer work or jobs, and use this to decide whether you'll help others out. You don't have to get a job when you're a teenager—and when you're under a certain age, it's nearly impossible to find one—but that doesn't mean that you're unable to help out! Consider volunteering, doing odd jobs for others, or helping someone to learn something they don't know. This can do wonders to help other people! It will be helpful for future employment after college to have a job or volunteer so you can have valuable work experience. . Volunteering doesn't have to happen outside of the home. If you have an internet connection, you can volunteer online—for example, editing wikiHow articles about your favorite subjects. Are you interested in animals? Volunteer at an animal shelter or collect supplies for your local non-profit shelter. Are you good with people? Find a job or volunteer work that's oriented around talking to others. Can you design complex web pages with minimal effort? Offer to help others learn web design. Take your talents and interests and find something you can do based around those. It can be a great help to volunteer or work, and have fun at the same time! If one of your talents is that you're an all-A's scholar, see if there's a program at your school that allows you to tutor struggling students. If not, try asking families that have younger kids or advertising a tutoring service—you may get some great opportunities!   It's okay to turn down a tutoring offer. If you can't tutor the neighbor's son because he's too loud and disruptive, or if you aren't good at a subject that somebody needs help with, it's okay to politely say, "I'm sorry, I can't do that job" or "I don't think your child and I work together very well". You can either choose to get paid for tutoring or do it for free. If you do choose to make it a job, however, don't overcharge. Few people will hire you if you charge ten dollars an hour! Some organizations will host activities to donate to certain causes—for example, walks to support cancer research collect money and donate it to groups that do cancer research. Other activities seek to spread awareness of illnesses, or acceptance of disabled people. Consider participating in these.  Be sure you know what group the activity is supporting. Some groups are well known for being surrounded by controversy. Do careful research on an organization before participating in any of their events. You don't want to support something that causes more harm than good. You don't need to participate in giant volunteer organizations to make a difference. Consider doing basic things to help people have a brighter day—compliment your classmate's poem, tell someone they look fantastic, help somebody pick up their things if they drop them, hold the door open for others who are struggling to carry things, and so forth. Something that seems little to you can turn someone else's entire day around. Get out there, and help to make the world a better place by making others' lives more enjoyable!
Summary:
Consider volunteer work. Avoid thinking that you "can't help anybody". Build off of your interests and talents. Consider tutoring younger kids. Participate in fundraisers and activities for causes you support. Do things that make others happy.
