Pearls are magical as they are the only gemstone that comes from a living organism! They have been cherished for centuries and used to be more valuable than diamonds. Today, they are considered a staple in any jewelry collection. There is a lot to know about pearls. Pearls 101 There are many different types of pearls. The most valuable and the rarest pearls are natural pearls. Natural pearls are those grown without outside help of any kind. Today natural pearling is only done in the Persian Gulf around Bahrain. Natural pearls are extremely valuable as only a small percentage of pearls will naturally achieve the desirable size, shape and color to create a piece of jewelry. Most pearls used in modern jewelry are cultured. They are still real pearls but grown with human intervention to ensure the final product has the right shape, size, and color to use for jewelry manufacturing. Don't confuse cultured pearls with imitation pearls, which are usually a coated glass bead. Cultured pearls were first introduced to the market by Kokichi Mikimoto in the early 1900s. There are four types of cultured pearls used for jewelry: Akoya Pearls Akoya pearls are the most popular type of cultured pearl. The pearls come from the akoya oyster. They are popular for use in jewelry as they often come in near-perfect round shapes, bright luster and neutral colors like white, cream, champagne, or silver that are desirable for most customers. Pink, green, or black Akoya pearls are usually color treated. Akoya pearls come in a range of sizes. They can be as small as 1 mm and as big as 11 mm. But the average size for and Akoya pearl is considered 7 mm, which is relatively small compared to other types of pearls. Akoya pearls are farmed mostly in Japan and China. Vietnam, Thailand and Australia also produce small amounts of Akoya pearls. South Sea Pearls South Sea pearls come from the South Sea pearl oyster. They are cultured in only in Australia, the Philippines and Indonesia. Because of their large size they generally have a longer growth period compared to Akoya pearls. This type of pearl is much larger than the Akoya pearl: the smallest South Sea pearls are 8 mm and they can be up to 20 mm. The average size for a South Sea pearl is 12 mm. Only a small percentage of South Seas are perfectly round. More common shapes are baroque and drop, making them a great fit for unique designs. They can be white, silver, or gold. Gold South Sea pearls are the most prized type of cultured pearls among collectors. South Sea pearls are considered the most valuable type of cultured pearls due to their large size, their relative scarcity, and unique color. Tahitian Pearls Tahitian pearls come from the black-lip pearl oyster, and are the only pearls that are naturally dark. Many people describe the color as black, but they are not pitch black. Tahitian pearls usually have a dark body color like gray or brown with blue, green, purple or pink overtones. Their iridescent colors is what makes Tahitian pearls so unique. Similar to South Sea pearls, Tahitian pearls are naturally larger. They come in sizes between 8 mm and 18 mm, with 10 mm being the most popular size for a Tahitian pearl. Tahitian pearls are farmed exclusively in French Polynesia. Due to their unique colors and relative rarity, Tahitian pearls are considered to be the second most valuable type of cultured pearl in the world. Freshwater Pearls Freshwater pearls are the most common type of cultured pearl. They come in a wide range of sizes, shapes and colors. Freshwater pearls can be produced by different mussels that live in freshwater lakes and ponds. Unlike most other pearl oysters, these muscles can grow many pearls at once. Freshwater pearl shapes range from very baroque to almost perfectly round. They also come in fun shapes like stick, button or coin. They can be classic white but also come in lavender or pink and are often dyed to achieve more intense bodycolor. They also come in many sizes: a freshwater pearl can be as small as 1 mm and as big as 15 mm and larger. While they can be grown in many regions, China is the main producer of freshwater pearls. Freshwater pearls are widely available and generally considered the least valuable compared to the three other types of cultured pearls. What to know about Pearls? Because pearls are a unique gemstones, their value is determined different compared to other gems. The main quality indicators for pearls are: Size Generally speaking, larger pearls are rarer and more valuable than smaller pearls of the same type. Shape Round is the most difficult shape to culture, making it the most desirable overall. But pear, oval, or baroque pearls are also prized and often work better in certain pieces of jewelry. Baroque in relation to pearls means irregularly shaped and has nothing to do with the time period the pearl was cultured or harvested in. Color Pearls come in many different colors. Their color can be made up of: Bodycolor, which is the dominant color. Overtone, which is the translucent color (or colors) that lies over a pearl’s bodycolor. Orient, which is the shimmer of iridescent colors on (or just below) the pearl’s surface. All pearls display a bodycolor, but only some will show overtone, orient, or both. It is hard to tell which color is considered the most valuable as this varies by pearl type. Luster This factor is often considered the most important one. Luster is the sheen or glow that gives pearls their unique beauty. It is graded on a scale ranging from excellent to poor. The higher the luster, the higher quality and more valuable the pearl. Excellent means that reflections appear bright and sharp Very good luster is defined as reflections appearing bright and almost sharp Good luster means reflections are bright but slightly hazy Fair luster is when reflections are weak and blurred Poor luster is defined as reflections being dim and completely blurry Surface quality Because they are grown in a living organism, most pearls never achieve perfection, even when grown with human intervention. A cultured pearl can have irregularities or abrasions on the surface. The smoother the surface of the pearl, the higher its quality. Nacre quality Nacre is the iridescent layer on the pearl's surface. The thickness, uniformity, and durability of this layer are important quality factors. In fact, nacre quality is closely related to luster, as a pearl with thin nacre will usually appear dull. Matching Matching is an important factor for strands of pearls. The goal is to match pearls of the same size, shape, color, and luster to create a perfect strand or matched pair of earrings. However, in many jewelry designs this factor does not play an important role as size variation may be desirable for certain pieces. What should I know before buying pearl jewelry? Pearls require special care. At a 2.5 to 4.5 on the Mohs Scale , they are one of the softest gemstones used in jewelry. They are also sensitive and require special care to last. Pearl care 101 Because pearls are low on the Mohs Scale, which mens they will be easily scratched, they shouldn't be stacked with gemstone jewelry. Pearls are sensitive to extreme heat. They can burn, crack or become discolored when exposed to high temperatures. They are also easily damaged by acids - including those in perfume, cosmetics, and even body oils or sweat. This is why it's said pearls should the last thing you put on and the firstling you take off. It is generally recommended to wait 30 minutes after applying any personal care products. We always recommend that you stick to warm, soapy water and a soft cloth for cleaning your jewelry at home. With pearls, it is especially important that you never put them in an ultrasonic or steam cleaner both of which will damage the gem. You can wipe pearls with a very soft cloth after each time you wear them to remove any body oils. Store pearls away from gemstone and diamond jewelry to avoid scratching. A soft pouch or a soft lined jewelry box is best for storing them. Pearls are organic and contain trace amounts of water, so make sure they have some room to breathe. Storing pearls in an airtight environment may cause them to become brittle and dull over time. But do not let them collect dust, as the dust particles will scratch their surface.

The biggest misconception about fine jewelry is that it needs minimal care to last forever. The opposite is true: the higher quality your jewelry the more careful you want to be. Just like your finest clothes or shoes, there is a way to preserve the beauty of precious jewels. The materials that fine jewelry is made of are delicate. While it is true that solid gold and platinum jewelry won't stain your skin, they are far from indestructible. High carat gold and fine gemstones are fragile treasures! Here is how to preserve them: What to Know About Gold Jewelry Care First, it is important to keep in mind that there is no jewelry made with pure gold. All commercially available gold is alloyed with other metals. The karats of gold tell you how much pure gold is present: 14 karat gold has 58.3%, 18 karat gold 75%, and 22 karat gold 91.6% pure gold. So, when you see solid gold jewelry it is real gold - as opposed to gold plated - but it will never be 100% pure gold, as this would be impossible. But more is not always better -it depends on what your needs are. The higher the gold percentage, the softer the metal. Pure (24 karat) gold is so soft, you could easily bend it - not something you want from a ring or bracelet. 22 karat gold can be used for chunky rings but is never recommended for prong setting precious stones or clasps due to its softness. At Meluzza, we use 18 karat gold, which is hard enough to set stones safely with prongs but it still needs to be treated with care. Because gold is soft it will scratch easily with daily wear. You can always repolish it but scratches aren't a quality indicator, they just indicate how much you wore your jewelry. White gold is higher maintenance. Since gold is naturally yellow, you will notice a yellow touch overtime. White gold may need to be replated regularly to maintain the white color, and how long the plating lasts will depend on how well you take care of your jewelry. With impact and improper care, gold can also bend or even break. What to Know About Platinum Jewelry Care Platinum is more easy going, as it is always used in its pure (or 99.9%) form. However, platinum is more malleable, which means it is easier to bend. This is why you want to be careful with any impact and avoid putting pressure on platinum jewelry. Platinum also scratches much more easily than gold. Some people find the scratches desirable as they build a so-called patina over time. When Not to Wear Fine Jewelry: 1: To the Gym and While Exercising While it should be obvious that wearing rings while doing weights is a bad idea, other activities aren't safe either. Rings can also bend while doing any activities that require you to have a strong grip, such as biking (or spinning), playing tennis, or rowing to name a few. It's not just rings that aren't safe at the gym or during exercise. The gym is a place where you are generally more likely to bang your jewelry on something, which may result in damage to gemstones, and any exercise puts you at risk for falling. The impact and pressure on clasps can cause them to weaken and eventually open. This is not a sign of poor quality - no jewelry clasp is designed in a way to withstand strong, prolonged pressure without popping open. Otherwise you wouldn't be able to take it off. Chains can also tangle, which doesn't cause damage right away but is tricky to deal with, and may in the long term cause them to snap. And all the sweat can make gold and gems look dull. 2: At the Spa The spa is an environment with extreme temperature changes, high humidity and/or dry air, all happening minutes apart. Many gems do not take all of the above well. It is safest to remove your jewelry before any activities that include strong heat, humidity and dry air. Additionally spas often use chlorinated water, which you want to avoid - more on that below. 3: The Pool Now let's talk about chlorine: the chemical damages metals that gold is alloyed with. With frequent exposure to chlorine, gold gets brittle and prongs may break off. While platinum is not affected by chlorine, the chemical may also affect certain gemstones, so just avoid jewelry in the pool altogether, especially if going in for longer periods of time. 4: The Beach Losing your jewelry in the ocean is a very sad and in most cases irreversible experience. But saltwater can also damage and discolor metals, such as gold and platinum, and can slowly erode the polish of most gemstones. Even if you are staying out of the water, sand will be a problem as well. Tiny sand kernels that are hard to clean out are likely to get stuck in your jewelry making it look dirty. And you will hopefully be applying sunscreen regularly which can cause a film to form on jewelry, making it appear dull. 5: While Cleaning Even when doing light cleaning, it is best to remove any jewelry. The harsh chemicals can damage metals and weaken prongs, which increases the risk of losing gemstones. Many gemstones also don't take exposure to most chemicals well. 6: The Shower When diamonds and gemstones are exposed to oils, soaps, and lotions, it can leave a film over them resulting in less sparkle. Softer stones like pearls or opals can be damaged when worn in the shower. Wearing solid gold jewelry in the shower will not harm the metal itself, but it can reduce the shine therefore it is not recommended. Remember that jewelry should always be the last thing you put on. Lotions will not just leave an ugly film on your jewelry, the chemicals can react with the metals that gold is alloyed with and cause discoloration or tarnishing. If you frequently put on jewelry right after applying lotion, makeup or perfume, your solid gold jewelry may leave a dark mark- this is not a sign of poor quality, just an expected chemical reaction. 7: To Bed This one may be controversial, but it’s generally best to remove jewelry before bed. When you sleep with any gemstone jewelry on, you risk breaking the stone. Additionally, chains on pendants can stretch, weakening them. Friction from sheets and movement while sleeping can wear down the metal and loosen prongs on rings and pendants, potentially causing damage to your jewelry. 8: To the Nail Studio Make sure you remove all rings and bracelets before getting your nails done. Acetone will damage your jewelry and may also cause damage to some gemstones. As much as you try, some of it is very likely to drip down on your precious rings, so better to just take them off! 9: To the Club I know you want to show off your jewelry but leave your best pieces at home before a night out. If you are planning on dancing all night you are likely to put impact on your jewelry. You might also sweat a lot and risk banging jewelry - especially gemstone jewelry - against objects. Not to mention, the high risk of falling asleep in your jewelry after a night out. 10: While Cooking Not only is food likely to get stuck in your rings making for an unpleasant look, the cooking oils may spray onto your jewelry and make it look dull. You may have to frequently wash your hands and dishes, so it's best not to wear fine jewelry while doing serious cooking - reheating leftovers is ok! A Gray Area: Stacks Stacking your jewelry is causing scratching and often damages gems. Anything stacked with a diamond will become scratched, as diamonds are the hardest stone and scratch both other gems as well as all metals. But the metals rubbing against each other will also cause scratching. This is well known and most people prefer to take the risk. You just need to be aware that the jewelry you stack will start looking dull faster. And if you are stacking gemstone jewelry, you may damage gems faster, especially if you mix gemstones and diamonds. A "neck stack" (which is a lot of chains and necklaces combined) can also get severely tangled, sometimes resulting in chains to snap. If you are ok with having scratched and tangled jewelry, go for the stack. Just know the look comes at a price. Avoid stacking any softer stones, like pearls or opals. How to Maintain Your Fine Jewelry Fine jewelry requires a lot of maintenance to last. If you aren't willing to care for your jewelry, don't be surprised when the "investment" piece breaks or looks dull after a few months. The easiest way to maintain its beauty forever is to avoid any of the activities listed above. You should also get a professional assessment at least once a year or any time something doesn't feel right. There are certain things you can check at home regularly: Check if your gemstones are secure: gently move your finger over the stone to check if it's loose. Asses your clasps: clasps can weaken with frequent wear, so make sure you check that closures and clasps work well periodically. Look out for chips: if you notice a small chip on your gemstone, make sure to take it in for further evaluation. Check the shape of your rings: if you happen to keep your ring on for one too many gym sessions, it could bend out of shape, which weakens its structure. If you notice anything looking off, make sure to get it looked at. I know you will probably continue doing a lot more activities with your jewelry on than recommended. If you choose to do so just know that damage is a common side effect. It's easy to blame it on quality and your jeweler. But if you went on a run in high heels, you wouldn't be surprised they aren't wearable afterwards. Same should be true for a fine bracelet you wear to the gym all the time.
