Like most gemstones, diamonds require cutting and polishing. The skill of a diamond cutter is required to unlock the extraordinary and unique beauty of a diamond. Many gemologists believe this is the most important - though most misunderstood - of The Four "C"s that determine a diamond's quality and value. Even if a diamond has perfect color and clarity, a poor cut will cause it to lose sparkle.

Cut refers to the execution of a diamond's design, the skill with which it was cut, the quality of its polish, and the overall symmetry of the stone. Key factors include the stone's roundness, depth, width, and the uniformity of its facets.

Cut is also used to describe the shape of a diamond. In addition to the round brilliant, other popular cuts include emerald, marquis, pear, oval and square.

Each diamond is cut according to an exact mathematical formula. The most common cut, the round brilliant, has 58 facets, or small, flat, polished planes designed to yield the maximum amount of light to be reflected back to the viewer. This reflection, known as brilliance, is an extremely important factor in evaluating the quality of a diamond.

Although there are several systems for determining the quality of a diamond's cut, they can be broadly characterized as Ideal, Excellent, Very Good, Good, Fair or Poor. Ideal and excellent cuts represent the top of the line; most or all of the light that enters the diamond is reflected back to the eye. A stone with a very good or good cut grade reflects nearly as much light as the ideal and excellent cuts, but is available at a lower price. Fair cuts are still considered quality diamonds, but have considerably less brilliance than good cut grades. And a poor cut is a diamond which is off in its proportions and subsequently loses most of its light out the sides and bottom.

In other words, a well-cut diamond has the right angles and proportions to release the inner brilliance of the stone and project its maximum amount of fire and sparkle. A poorly cut diamond is a "dull" diamond that may even have some "dead" spots inside.

A diamond's proportions, particularly the depth compared to the diameter, and the diameter of the table (the largest and topmost facet of the diamond) determine how well light will travel within the diamond and back to the eye.

Two keys to a diamond's brilliance are its crown and pavilion. The crown is the top portion of a diamond extending from the girdle (the outermost edge of a cut gem) to the table. The pavilion is the part of the diamond below the girdle. Above the girdle of a brilliant cut diamond are 32 facets plus the table. Below the girdle are 24 facets plus the culet, or point. Just a few degrees off the standard can have a drastic impact on a stone's brilliance. But there is some leeway. Cutters can compensate by adjusting crown angles, table sizes and pavilion angles to produce the best possible results for each stone.

Whether you're a newcomer to the gem world looking to add color to your wardrobe, or a veteran gemstone wearer fine-tuning your look, finding the right gemstone jewelry is a key way to express your own personal style, uplift your appearance and spirit, and convey to others what you're all about. But this doesn't have to be a grueling decision. Here are some practical tips for selecting gemstone jewelry that works best for you.

Developing Your Own Style
First of all, any gemstone jewelry you select must be comfortable. For instance, make sure necklaces hang at the "right" length for you and lay well around your neck. Experts offer similar advice for earrings: with dangling styles, make sure they hang at a comfortable length, fit well against the ear and don't tip forward. Likewise, bracelets and rings should fit comfortably and shouldn't slide off with a simple shake of your arm or hand.

Next, the jewelry must be appropriate for your personality and lifestyle. A glitzy necklace that would dazzle for a night out on the town probably wouldn't work for someone with a more casual outlook. Intent is important. Are you looking for a fashion accessory to match certain outfits, a particular season/event or a specific function, such as jewelry for work? Or are you looking for a piece you will wear everyday? Obviously, things like fashion, price, versatility, durability and other factors will play differing roles in your buying decision, based on your intent.

As for which color best suits you, one way to determine this is to take stock of what's already in your closet. What clothing styles, colors, materials, lengths, etc. are most prevalent? This will give you important clues about the specific gemstone jewelry that will work best for you. In addition, look at your makeup, scarves, hair accessories, and current jewelry for more cues about the jewelry colors and styles most appropriate for you.

Finally, consider your physical features: body type, face shape, finger/hand length and width, hair/eye color, complexion and other characteristics. These factors also will play a key role in determining which gemstone jewelry will look best on you.

Seeking Quality
Once you've got the style down, you want to be assured of the quality of any piece you're interested in buying. Keep in mind that quality determines the value of a stone. Like diamonds, gemstones are judged by the "Four Cs" of color, clarity, cut and carat weight, with color the most important consideration, by far. The better the color, the higher the price. Better clarity and better cut also cost more - and generally, the larger the stone, the more it will cost per carat. Even to an untrained eye, many of these kinds of differences can be seen when similar stones are examined side-by-side.

Other factors that may influence the price of a gemstone include whether it is readily available on the market or subject to supply limitations; whether it's a "hot" color or stone right now, or for various reasons may be unpopular; whether it's a single stone or part of a matched set, particularly in special shapes or cuts; and sometimes, its origin (for every stone, there is a particular location known for producing the finest quality variety of that stone - and often, you'll pay more for a stone from that prized region because of its reputation).

But quality extends beyond simply examining the stone. You need to pay special attention to the setting, as well. Make sure the metal holds the stone firmly and squarely in place. Check prongs to make sure they are tight and sturdy. Look at the finish - is the metal well-polished with no pockmarks or other imperfections? Also, turn the piece around and examine the back - a well-made piece of jewelry will have a good finish on both front and back. If the piece is gold, check for a karatage stamp, as well as a company trademark stamp. This means the company is standing behind the product and assuring you the karatage is as stated. As for bracelets or necklaces, check the clasps, as well. A quality piece of gemstone jewelry will have sturdy, quality clasps.

Whether you're accessorizing for work or play, having the right jewelry can go a long way in helping you project an image of confidence and individual style. But how do you develop that style when you're building your jewelry wardrobe from scratch?

According to the experts, developing your own style means "knowing yourself": what you like and dislike. To determine this, ask yourself "What is my ideal?" and "What turns my head?" Decide if that means contemporary or classic jewelry styles; streamlined or detailed; colored stones or white diamonds.

Also, listen to style-related comments from others. What outfits or accessories do people compliment you on? This will give you important clues about the kind of jewelry that looks best on you.

Next, make sure what you've selected fits your personality and lifestyle. For instance, if you spend a lot of time doing activities outdoors, consider simple earrings that won't dangle too far and get in the way. Comfort is a must. If something is either physically or psychologically uncomfortable to wear, you'll have trouble projecting the kind of confidence and competence integral to developing a personal style.

As for the jewelry itself, stick with the basics in the beginning. The rule of thumb is to always buy the best-quality basics you can afford, so you can add matching pieces later. In gold jewelry, such basics should include a gold chain necklace, classic hoop or button earrings, and a link bracelet. Additions could include slide-on pendants or drops to create different looks with your necklace and earrings. In diamond jewelry, classic stud earrings or a solitaire pendant should be among your first purchases.

Experts advise that you begin with classic shapes that look appropriate with a variety of outfits, and then add pieces that offer versatility of wear or a fashion touch, such as different colors or finishes.

And don't overlook the importance of selecting jewelry that suits your body type. For instance, your height and bone structure play a big role in determining the kind of jewelry that looks best on you. A smaller, petite woman would be better served with necklace lengths that fall below the breast but above the waist to elongate her figure. Meanwhile, a tall, thin woman may want to select a choker that cuts the line of the neck and de-emphasizes her height. And a full-figured woman should stay away from jewelry that's too small or delicate.

Equally important to style are face shapes. The four basic are oval, round, rectangular and heart-shaped. If your face is oval, triangular-shaped earrings are especially flattering. A round shape should seek elongated, dangling styles that draw the eyes down, rather than around. For a rectangular face, try jewelry that adds width, camouflaging the length of the face. And for heart-shaped faces, look for earrings that are wider at the bottom, because style can soften a pointed chin look.

And don't forget to consider your hand type if you're purchasing rings. If you're long-fingered, wider bands will look especially good on you. If you're short-fingered, thinner bands and stone shapes such as marquise or pear that elongate the hand would be a good choice.
