5 Tips to Avoid Fake Gemstones

Cardinal_gemsLike many coins, there are increasing amounts of fake gemstones flooding the market. Natural gemstones are created by nature with no human interference. Jewelers may cut or polish natural gemstones, but they are not altered other ways.

With so many synthetic or imitated gems available today, it can be very hard to distinguish a real gemstone from a fake, especially over the Internet. Therefore, we’ve provided some tips to help you avoid imitations:

Too good to be true

The first sign of fake gems is certainly a low price. That said, you should always avoid gemstone deals or sales that appear too good to be true. Instead, make gemstone purchases from reputable dealers that guarantee authentic gemstones and include cash-back returns. Plus, most jewelers will have tests and equipment that can classify authentic gemstones and reveal imitations.

Compare with real gems

When possible, compare gems with real gemstones. Taking a gem class or workshop is a great way to gain access to authentic samples. When examining real gemstones, always use a loupe. The higher the magnification the easier it will be to spot a fake. Also, real gemstones have minor imperfections and inconsistencies, whereas man-made imposters will look waxy or slick.

 Weigh the stone

Generally speaking, synthetic gemstones weigh more than real ones. Synthetic gems are denser, however, you can clearly feel the weight difference between the two types of gems. Synthetic gems often have chemicals added to make them look real, making them heavier than genuine stones.

Examine the color

Carefully examine the characteristics of the gemstone. A fake gemstone will have an uneven luster and color. Uneven color could suggest a poor dye job. Some frauds even paint the tip of a gemstone to make the color stand out better. Also, synthetic gems typically have more sparkle than real gemstones.

Talk to an expert

Before making a purchase, talk to an expert. You should also consider having the gem appraised before purchasing it. A gemologist will be able to spot a fake right away. He or she will also be able to confirm the value of the stone. There are plenty of books on gemstones available. Pick one up and study it before you make any purchase.

Synthetic gemstones have similar properties as natural gems, but they are man-made. Because fake gems are becoming more prevalent throughout the jewelry industry, it’s important to educate yourself about fake gemstones. This will help you to understand what you are buying when you purchase jewelry or loose gemstones.

How to Care For Precious Jewels

gemstonesIn addition to rare coins and bullion, Great American Coin is proud to offer a wide selection of natural gemstones and jewels! With their natural beauty and luster, precious jewels make for great gifts. However, much like other types of jewelry, natural wear and tear can be inevitable. Therefore, it’s important to know how to properly take care of your jewels and gemstones.

Soap and water

Many gemstones require unique care and treatment in order to prevent damage. For that reason, your safest bet is old-fashioned soap and water. Just combine a bowl of warm water with a few drops of liquid dish detergent (like Dawn) and soak gemstones for five minutes.

Use a soft brush

One of the safest ways to clean your precious jewels is with a soft-bristle tooth brush. The brush must be soft, or you risk damaging the gemstone. Warm soapy water and a soft brush will often do the trick. After cleaning, rinse in warm water and dry with a soft cloth.

Household glass cleaner

Another popular cleaning method among jewelers and gemologists is to cleanse precious jewels with glass cleaner. After you let your jewels soak in lukewarm, soapy water, transfer them into another bowl filled with glass cleaner and let them sit for a couple minutes. The glass cleaner will remove any oil and dirt, leaving your precious jewels looking vibrant and shiny!

Store gemstones separately

This last step is very important: Store your precious pieces carefully. You should always keep precious jewels in separate boxes or wrapped individually in a soft cloth. Gemstones can scratch easily, especially when they’re in necklaces, rings and other settings.

If you are ever nervous about how to properly clean jewelry at home, take it to a jeweler. Natural gemstones and jewels are an investment and should be treated as such. With a little tender loving care, your precious jewels will give you many years of enjoyment and may even become an heirloom piece for generations to come!
