Caring For Your Jewelry Collection

Whether your prized possessions are collectable coins or precious pieces of jewelry, it is important to know how to care for them correctly. Keeping your jewelry collection in pristine condition will not only allow it to keep its monetary value, but will also preserve the beauty of your collection. If you are looking to buy or sell jewelry near Rockville, MD, keep in mind that chemicals in everyday products can cause jewelry to lose value and luster. To learn about what can damage your jewelry in your everyday life and how to properly care for your prized collection, read on.

Everyday Causes of Jewelry Damage

From the heat of the blow dryer to the daily use of cosmetics, everyday activities can lead to depreciation of your jewelry collection. Heat, even from overexposure to the sun’s rays, can cause some precious gemstones to change in color, affect their durability, and, in some cases, cause fractures. Heat is not the only cause of jewelry damage—the use of chemicals can damage precious metals and gemstones as well. Hairsprays, lotions, and household cleaners can all contribute to jewelry losing its sparkle and valuation.

Steps to Care for Your Jewelry

Washing gemstones in warm water with a dash of soap and a soft brush can help to prolong the lifespan of your collection. Simply taking off jewelry prior to using household chemicals, applying cosmetics, or swimming in pools that contain chlorine can help to keep your jewelry in ideal condition. Lastly, properly care for your collection by storing it properly. Some gems, such as opals and pearls, require special dry storage to keep them durable and shining brightly.

How Coins Are Made

People often collect rare coins without giving much thought to how they are created. However, the coin creation process can be incredibly fascinating. This year alone, America’s two mints will produce 28 billion coins.

All coins start out as blanks that are punched through coiled strips of metal. Once this stage is completed, the blanks are sent off to an annealing furnace, where they are softened. Only the good blanks are sent to an upsetting mill, where the edges of each coin are raised. During the striking phase, coins are stamped to show chosen designs. In order to make sure each coin is perfect, it is inspected and counted before it heads to your local bank.

Amazing Facts about Diamonds

Prior to reaching a jewelry display case, it takes diamonds billions of years to transform from carbon into precious stones. Whether people are looking to buy or sell this precious gem, it can hold sentimental and monetary value for all who possess it. If you are getting ready to go shopping for a diamond, be sure to read on to learn a bit more about these amazing stones.

Diamond Formation

Billions of years ago, diamonds began forming several miles below the Earth’s surface as temperatures exceeding 2,000 °F combined with immense pressure to transform carbon into crystals. These crystals were then brought to the Earth’s surface at speeds of up to 30 miles per hour by volcanic eruptions. Today, diamonds are mined in the cooled parts of volcanic matter, called Kimberlites. Due to how diamonds are formed, they are not only naturally fireproof, but are also the hardest known natural material on Earth.

Diamonds throughout History

As with gold coins, diamonds have long been a coveted possession. Although diamonds are now purchased in America more than anywhere else on Earth, India was the first country to recognize their beauty—they were initially collected in rivers and streams there. Eventually, India’s diamond trade reached the nobility of Western Europe, where diamonds became the symbol of status that they still are today. The French Blue, a large diamond that was featured in the French Crown, later broke off into one of today’s most famous diamonds—The Hope Diamond. Today, diamonds are still just as treasured as they have been throughout history. In April of 2015, a 100-carat diamond sold at auction for $22 million.
