Understanding Rare, Precious Metals

Scroll down to explore a learning path based on this topic.
Playlist Description

Valuable metals are some of the most sought-after investments in the world. Rare, beautiful and timeless, these inconspicuous elements on the period table are worth quite a bit to your wallet. Take gold for example—one metric ton of it is so dense it could be contained in 37 cubic centimeters and be worth more than $12 million. Platinum, one of the world's rarest metals, is naturally found in the earth's crust, courtesy of shattered meteorites from two billion years ago. Today, platinum is considered the crème de la crème of precious metals, worth a whopping $1,620 an ounce.

Before you throw those old hoop earrings or hand-me-down cufflinks away, check out this playlist—you may be the owner of cashable precious metals. Explore the precarious world of precious metals, what give them their value, and discover if your junk drawer is really a hidden treasure chest.

Follow these tips to learn how to find your pot of gold. Step 1: Bite the gold Bite down onto a gold coin or jewelry piece. Fake gold will not dent at all on a bite test. Real gold will, but so will some newer methods of gold plating. Tip Store gold jewelry separate from jewelry with diamonds, or the diamonds might scratch the gold. Wrap gold in tissue paper or store it in a separate jewelry box. Step 2: Look for a stamp or other marking Examine the surface of the gold item to see if you can find a stamp or other marking that indicates a carat value. American-made gold items will have this type of mark, but items from other countries may not. Step 3: Examine the surface of the item Examine the surface of the gold item, looking carefully for any green or black spots that may be visible. These markings indicate fake gold. Tip Pay particular attention to edges and clasps when examining the surface of the gold, as this is often where the discoloration appears. Step 4: Feel the weight of the gold item Hold the gold item in your hand, and pay attention to the weight. Real gold is very dense and heavy, but fake gold will feel lighter. Step 5: Consult with an expert Consult with a jeweler or metal exchange expert to confirm the authenticity of your gold item. They can also help you determine a value for your new find and help you know whether you did indeed find real gold. Did You Know? In 1848, James Marshall found a few flakes of gold at Sutter's Mill in California. During the next seven years, nearly 300,000 people traveled to California to seek their treasure and look for gold.

Watch more Buying, Spending, & Shopping Tips videos: http://www.howcast.com/videos/398342-How-to-Tell-Real-Jade-from-Fake If you see a beautiful set of silverware or silver jewelry on sale at an amazingly low price, you want to make sure that you are getting the real deal. Step 1: Look for markings indicating sterling silver Examine your silver piece, and look for markings that indicate it is sterling silver. Check for stamps that say STERLING, .925, or 925/100. Tip Examine the clasp of a necklace and the inside of rings and bracelets to find a marking of sterling silver. Step 2: Look for British silver markings Identify sterling silver from England, Ireland, or Scotland by looking for other stamps. These markings are small, and often look like a lion or a coat of arms. Step 3: Look for markings indicating silver plating Look for markings that indicate that your piece is silver plated. These include stamps of single-digit numbers, stamps starting with the letters EP, and words like "heavy plate" or "triple." Tip Know that silver-plated pieces are actually coated with a very thin layer of silver. They have little monetary value because they contain very little precious metal. Step 4: Consult with an expert for other foreign silver Speak with a jeweler or metal exchange dealer if your silver is not from the U.S. or Great Britain. Other areas have different silver markings and different levels for measuring the purity of their silver. Step 5: Have your silver examined by an expert Consult with an expert if you cannot find stamps to help you tell sterling silver from plated. They can help you determine the authenticity of your silver and help you figure out a value. Did You Know? The process of electroplating, used to make a silver-plated piece, was invented in 1805 by an Italian chemist. It wasn't until the 1850s that it was used to make costume jewelry.
