When you purchase jewelry or wear pieces you have designed, it's always good to make sure you like what you're wearing.  How many times have you bought a bracelet but then never wore it because it pinched?  Or bought a necklace only to find it left a green ring around your neck?  Well Glamour magazine has listed seven simple tests you can do before buying or wearing a new item of jewelry.  You can even demonstrate these to your customers so they know your jewelry will work for them.

• Shop around and do your research. If you are interested in buying gold, sterling, or even brass, understand each metal and the costs--the research will be worth it! Gold is well over $1,000 an ounce these days, so vermeil, which is gold layered over sterling silver, may be a better alternative.
• Do the "snag" test. Run the piece of jewelry over your stockings, blouse and skin to make sure the prongs or metal don't tear your clothing or skin.
• Do the scratch test. Gently scratch your nail over the item to make sure that it won't scratch or peel. Sometimes inexpensive jewelry looks like gold or silver but it is actually just paint over inexpensive metal.
• Test the prongs. If you can lift a prong with your finger nail, chances are that the gemstone it is holding will fall out and the piece will be worthless.
• When buying fine jewelry, make sure that wherever you purchase from has a money-back return policy. You should have anywhere from 14 to 30 days to get a full refund on your purchase. If not, go to a store or retailer who will allow you to return if you change your mind.
• Wear and love your jewelry and don't save it for a special occasion. With proper care, your jewelry should last a long, long time and every day should be a reason to celebrate!
