Both silver and gold jewelry should be inspected regularly to make sure prongs are tight, clasps work correctly and no cracks or pulls have formed. Bring your jewelry into a jeweler every four to six months for a professional inspection; this could prevent a loss of a gemstone. Always polish your jewelry with a lint-free cloth after wearing to remove all oils and lotions that may have come in contact with your jewelry. Sterling Silver should be kept in a sealed plastic bag to prevent tarnishing. Never use toothpaste or bleach to clean your jewelry. Toothpaste is an abrasive which scratches all precious metals and gets stuck under prongs and in the design. Bleach is extremely corrosive on many metals, making the jewelry porous over time and prone to breaking.
Although it is possible for someone to change their own watch battery, it is best to leave it up to the professionals. There are extremely fragile parts inside a watch and without the proper tools an inexperienced person can permanently damage the mechanism. Also, each watch can take a different battery, most of which we have on hand and can change in just a few minutes.
