About Sterling Silver Jewelry Sterling Silver History Experts believe that silver alloy, used today as sterling silver, originated in continental Europe in the 12th century. Pure silver was found to be a soft and easily damageable material. When combined with other metals, most commonly cooper, it produced a tougher material that could be heavily relied on. Throughout the next few centuries, sterling silver was used as currency and for household items. It was often used as silverware and became the material used in a proper table setting between 1840 and 1940 throughout the United States and Europe. Because of this popularity, silver companies began to grow. During this craze, companies began to experiment using sterling silver compositions in jewelry, as it was a material that was easy to mold into intricate designs and gave a luxurious look with its metallic finish. Today, sterling silver is widely used in all kinds of jewelry styles and shines as beautifully as other precious metals, with the benefit of affordable pricing. Sterling Silver Composition While pure silver can be combined with many different types of metals, sterling silver is created when combining pure silver with copper. Sterling silver jewelry can be composed with different amounts of copper but is most often seen with the .925 stamp, meaning that the composition is of 92.5 percent silver and 7.5 percent copper. This has been found to be a good combination for maintaining the silver's durability without harming its sparkle. Caring for Your Sterling Silver Jewelry Silver should not come into contact with harsh household chemicals such as bleach, ammonia, or chlorine. To avoid scratches, store silver in a lined jewelry box or pouch, as it is prone to tarnish as it naturally reacts with sulfur or hydrogen sulfide in the air. Cleaning and wearing silver jewelry regularly will prevent this and help maintain its shine. Immediately upon noticing any discoloration, use a gentle polish made specifically for removing tarnish.

Gold Purity The purity of gold is measured in karats. Pure gold measures 24 karats but is too soft in this state to be used effectively in jewelry. So it is alloyed with other metals--silver, copper, nickel, and zinc--to increase its strength and durability. Common measurements once the alloy is added are 18 karat (75% gold), 14 karat (58%), and 10 karat (47.7%). In the United States, the legal karat limit for the metal to still be considered gold is 10 karats. A higher karat measurement in gold content indicates a greater value of the jewelry piece. Gold jewelry should always be stamped with the karat mark, either 18k, 750 (European marking for 18k), 14k, 585 (European marking for 14k), or 10k. In addition, to assure its quality, the piece should be stamped with the manufacturer's trademark or country of origin. Gold Color The color of gold may vary based off of the type of metal alloy included and the percentage of the metal alloy used. Most commonly, gold is available in yellow, white, and rose coloring. Yellow gold is the most common color and is usually alloyed with silver and copper. Yellow and white gold are similar in strength and malleability, making them perfect for jewelry that is worn daily. White gold is alloyed with nickel, copper, and zinc--and while it looks similar to platinum, it has vastly different properties. Rose-colored gold is alloyed with copper and is often used to accent white or yellow gold. The saturation of color varies from piece to piece and according to gold content. Caring For Your Gold Jewelry To keep gold shining and scratch-free, avoid contact with chlorine and other harsh chemicals. Do not wear jewelry during rough work and be sure to store it in a fabric-lined jewelry box or pouch. To clean gold jewelry, use warm water, a mild soap, and a soft bristled brush, if needed.

Cubic Zirconia History In 1937, Cubic Zirconia was first discovered by German mineralogists, M. V. Stackelberg and K. Chudoba. Little did they know, the tiny crystals that they discovered would move on to become a popular synthetic gemstone. It wasn’t until the 1970s that Cubic Zirconia was first used in the jewelry world, when scientists began growing the crystals in the laboratory. In the 1980s, Cubic Zirconia use in jewelry continued to grow and today is it one of the most popular diamond substitutes available on the market. Composition Cubic Zirconia is the cubic form of zirconium oxide that is created in a laboratory. Its durable material allows the synthetic stone to be molded into a variety of shapes. The stone offers brilliant shine and flawless clarity. Cubic Zirconia is available in a wide range of colors, including a colorless form that is an economically important competitor to natural diamonds. Caring For Your Cubic Zirconia Jewelry Like natural diamonds, Cubic Zirconia needs to be cared for in order to maintain its original brilliance and shine. Clean with warm-to-hot water and a soft brush with a mild soap, then immediately dry with a clean cloth after rinsing. Avoid contact with perfume, body lotion, hairspray or any other chemical that may harm the shine of the stone. Freshwater Cultured Pearls These pearls are gathered from freshwater lake and river mollusks. Most Freshwater pearls come from China and they can be mostly round to off-round, or rice-shaped to baroque. They look similar to Akoya pearls, but are the perfect gift when on a budget. They might be slightly less symmetrical, smaller, or not as easily matched, but these minor differences provide a major value for the price. Cultivation Pearls are produced naturally in the body of salt and freshwater mollusks, such as oysters and mussels. When these animals sense an irritant, such as a grain of sand, they produce a soft coating of calcium carbonate substance around it. The result is a pearl. Because perfectly round, naturally produced pearls are so rare, a process known as cultivation was developed by Kokichi Mikimoto in the early 1900s. A small bead of polished shell, the nucleus, is used as an irritant and delicately inserted into the mantle of a mollusk. It takes approximately 20-24 months of intensive husbandry to cultivate a saltwater pearl and somewhat less time to cultivate freshwater pearls. The harvest usually takes place during the months of June and September. Color Mollusks produce pearls in a variety of colors, accommodating most personal preferences and budgets. The general color of a pearl is also known as the body color. Pearls typically range from white, cream, and yellow to pink, silver, or black. An overtone of secondary color is sometimes seen. For instance, a pearl may appear to be white, but upon closer inspection a rosy hue is detected. The body color would then be termed white-rosé. Color variation does not affect the quality of the pearl, though it should be noted that color matching is important when choosing pearls for some necklaces, earrings, or bracelets. In fashion jewelry, pearls can sometimes be dyed to achieve the desired color, which should be mentioned in the product description or specifications. Lustre The appealing, deep shine of a pearl is often what defines its beauty. This shine is produced by multiple layers of semi-opaque calcium carbonate crystals, called nacre. The nacre reflects light on the surface of the pearl, producing brilliance and sheen. Lustre is an integral feature in determining the quality of a pearl. Large pearls have a thicker nacre and, therefore, a higher lustre. When comparing a small Freshwater pearl to a large South Sea pearl, the difference is clearly visible to the untrained eye and should be considered when purchasing pearls. Shape While pearls come in many different shapes, the rarest and highest-quality are round. Akoya, Tahitian, and South Sea oysters tend to produce the roundest pearls, while those of Freshwater mollusks can be oval to slightly off-round. When considering a pearl purchase, whether it be a necklace, bracelet, or earrings, look for consistency in the shapes of the pearls. Many of the less symmetrical shapes are used in stylish jewelry which can be quite beautiful: the drop pearl's shape lends well to earrings, and the baroque pearl features irregular shapes that work well as necklace accents. In addition, a half sphere pearl called a mabe is often used in earrings, necklaces, and bracelets. Size An oyster's particular type and size has a direct effect on how large the pearl it produces will be, and pearls do come in a wide range of sizes. Round pearls are measured according to their diameter, while baroque pearls are measured by their length and width. A pearl's size does not necessarily affect its quality, but it does affect its price. Large, round pearls are rare and their lustre is usually high--this beautiful combination of traits is often reflected in the cost of such pearls. Average pearl sizes (in diameter): Akoya: 6-8mm Freshwater: 5-6.5mm South Sea: 11-13mm Tahitian: 11-12mm Keshi: 4-10mm Surface Markings Often when an oyster creates a pearl, the nacre does not develop smoothly. The surface of a pearl is judged by how many marks are visible in the nacre. These imperfections can be small and unnoticeable or quite large and distinct. Like diamonds, pearls are rarely flawless. However, high lustre or the way pearls are strung and set can help conceal surface markings. Care Proper care of pearls is not difficult if you remember that they are organic and produced by a living thing. Pearls are soft and delicate, but when cared for with common sense, they will maintain their lustre for centuries. The pearls should not come in contact with cosmetics, hairspray, perfume, chlorinated water, or other harsh chemicals. To keep them clean, let them be the last item put on when dressing, and the first item taken off at the end of an evening. The best way to maintain their lustre is to wear the pearls often, and wipe them down with a soft cloth afterward--pearls absorb the oils from skin, which helps keep them moist. Pearls should be stored in a cloth pouch or jewelry bag, separated from other jewelry to prevent nicks or chipping. Periodically, pearl strands should be restrung since the silk thread used to tie the pearls together breaks down over time.
