Over time,jewelry will lose its shine,get scratched,bent,dented and wear down.But jewelry will retain its beauty and value much longer if it is properly maintained. 


All fine jewelry should be treated with care. After wearing your jewelry, wipe with a clean, soft, barely damp cloth to remove any dirt or cosmetics. Store each piece of jewelry individually in the jewelry box to prevent scratching.


Exposure to chemicals can damage or discolor precious metals – gold, silver and platinum – and may harm some colored gems. Even everyday substances like hairspray, lotion, perfume or other cosmetics can contain chemicals that will permanently damage the surface of your pearls and other delicate or porous gems (like turquoise). Fine jewelry should be removed before diving into a chlorinated swimming pool or before using household cleaners. Many of these cleaners contain ammonia, which can be too harsh for delicate gems or vintage jewelry. Chlorine bleach, another common household solvent, can pit or damage gold alloys.


It's tempting for some to wear a favorite piece of jewelry always, never taking it off to wash dishes, bathe or sleep. Such treatment of your most precious possession can unfortunately shorten its life or put it in danger of being lost. Some tips to avoid risk of bumping, hitting, or scratching your jewelry:
Remove your jewelry when playing sports or at the gym.

Don't wear your jewelry in the pool, spa or sauna.

Don't wear jewelry when doing household chores.

Put your jewelry on after you have finished your hair and makeup to avoid spraying or getting unnecessary amounts of product on it.

Don't sleep in your jewelry.


 Proper jewelry storage is often overlooked.Jewelry should never be tossed into a drawer or on top of a dresser-that's asking for scratches and damaged gems.

Storing each piece of jewelry individually in the jewelry box to prevent scratching or tangles,and make sure any place you store jewelry is an acid-free environment.Many plastics and wood can contain acid,which will tarnish many metals.Keeping gold jewelry separate from silver items.


The easiest way to clean is just with a slightly moist soft cloth with a tiny bit of soapy water (warm water),then buff it with a dry cloth.For a slightly better polish put some clean ash (from a cigarette or fireplace),or white toothpaste (without whitener) on the wet cloth instead of soap.Another way is using only cleaners recommended or sold by your jeweler,and use cleaners specifically designed for your metal.

Be sure to rinse your jewelry in a glass of water to remove cleaning solutions since you risk losing loose stones – or even an entire piece of jewelry - if you rinse directly in the sink.


Jewelry should be checked every three months and cleaned frequently by a jeweler with professional training and a good reputation-asking friends or relatives for recommendations is a good place to start.

Q.What is Moissanite? 

A. Moissanite, also known by its chemical name, silicon carbide (SiC), is a naturally occurring mineral found in very limited quantities or as minute particles in the earth. The rarity of natural moissanite crystals large enough for jewelry prohibits their use.For years, scientists tried to re-create this extraordinarily brilliant material. Only recently, through the power of advanced technology, developed a way to produce in a laboratory Moissanite is truly a unique and beautiful blend of art and science.

Q. Is Moissanite natural or man-made? 

  Moissanite does occur in nature however, the crystals are tiny and rare. In fact, they are so scarce that enough gem-quality natural moissanite doesn't exist to create a pair of solitaire earrings. Today, beautiful lab-created moissanite jewels are available through a proprietary and patented thermal growth process exclusively . The growth process is very involved, technology intense and expensive all factors

Q. How do I care for my new Moissanite? 

A. While created Moissanite is extremely hard, durable and resistant to abrasion and chipping, it, like all other gemstones and jewels is not indestructible. Care for your moissanite jewelry just as you would other fine jewelry, taking care not to wear rings and bracelets when doing rough work or sports. Moissanite jewelry can be safely cleaned the same way your would clean other fine jewelry using a jewelry ultrasonic cleaner or commercial (non-acid based) jewelry cleaner.

Q. Is Moissanite a brand of diamond, synthetic or simulated diamond? 

A. No. Moissanite is not a substitute for diamond scientifically, chemically or emotionally. created Moissanite is a unique near-colorless jewel (chemical composition: SiC) that stands on its own and has superb fire and brilliance as compared to any other jewel and offers the value, quality and fashion that self-purchasing women demand.

Q. How is Moissanite different from a CZ? 

A. Moissanite and cubic zirconia (or CZ) are very different from each other. While they both are near-colorless, their similarities are limited to color. Moissanite has unique chemical, optical and physical properties which easily identifies and separates it from CZ. Cubic zirconium is widely synthesized by a number of companies, for use as an inexpensive diamond look-alike or simulant. By comparison, moissanite is not a diamond simulant, but rather a unique jewel, unlike any other.
In contrast, naturally occurring quantities of moissanite are so minute and scarce that they are not suitable for use in jewelry. creating moissanite crystals for jewelry use. These rare jewel-quality crystals are produced in limited quantities and are carefully hand-faceted into moissanite jewels once each crystal meets stringent quality controls.

Q. Does Moissanite have more dispersion (fire) than a natural diamond? 

A. Moissanite's remarkable dispersion (fire) its ability to break white light into the spectral (rainbow) colors is one reason so many women are enchanted by its beauty. With more fire than any popular gemstone including diamond, ruby, sapphire and emerald no other gemstone or jewel compares to created Moissanite . In fact, fire can be measured scientifically and with a dispersion of 0.104 moissanite has nearly 2.4 times the fire of diamond.The more times you see moissanite and the longer you look at it, the more you realize it's a jewel worth owning.

Q. Why does Moissanite have so much sparkle? 

Moissanite's superior brilliance and luster its ability to reflect more white light back to the viewer is another reason women around the world are choosing to own this incredible jewel. With more brilliance and luster than any popular gemstone including diamond, ruby, sapphire and emerald no other gemstone or jewel compares to moissanite. In fact, brilliance can be measured scientifically and is directly influenced by a jewel's refractive index. With a refractive index of 2.65-2.69 moissanite has nearly 10% more brilliance than diamond. These qualities make Moissanite created by Tianyu Gems the perfect indulgence and an excellent value.

Q. How do I care for my Moissanite jewelry? 

A. While created Moissanite is extremely hard, durable and resistant to abrasion and chipping, it, like all other gemstones, is not indestructible. Care for your moissanite jewelry just as you would other fine jewelry, taking precautions not to wear rings and bracelets when doing rough work with your hands to avoid sharp blows. Moissanite jewelry can be safely cleaned the same way you would other fine jewelry; for example, in a jewelry ultrasonic cleaner or by using a commercial (non-acid based) jewelry cleaner.
