1. How to Prevent Tarnish on Sterling Silver Jewelry

Why Sterling Silver Jewelry Tarnishes

Sterling silver contains 92.5 percent silver and about 7.5 percent of other metals, usually copper. When air touches sterling silver jewelry, oxidative reactions occur with sulfur. Moisture can also cause tarnish, as well as corrosion, on silver.

Some tips on how to help prevent tarnishing on your silver jewelry

- The best way to prevent tarnishing is to store clean, dry sterling silver in a dry airtight container

- Don’t leave silver jewelry in the bathroom unprotected, and do not wear it the shower, swimming pool or hot tub. Humidity and moisture can make tarnish appear faster!

- Minimize sterling silver’s contact to chemicals found in hairspray, perfume, body lotion, makeup, etc..

- After taking off your silver jewelry, clean it with a dry soft cloth, or polishing cloth, before putting it back into an airtight container.

- Remove silver jewelry khi doing regular household chores, sleeping or getting active sports

2. Some tips on how to clean sterling silver

Wash silver jewelry (without gemstones or pearls) in warm water with a few drops of mild dish washing liquid. Immerse the sterling silver in the water and gently hand wash. Use a cotton swab for tight corners, or soft baby toothbrush can be used for more abrasive cleaning if needed.

If the jewelry contains gemstones or pearls, do not submerge the entire piece into water. Instead, use a cotton swab with mild dish washing liquid to wash only the silver.

Thoroughly rinse your pieces after washing, and completely dry the sterling silver before storing, as moisture is one of the factors that contribute to tarnishing

We do not recommend using toothpaste or baking soda for cleaning as it may scratch the surface of the silver. Do not harsh chemicals such as bleach, acetone, etc, to clean your silver because they can actually make silver more dull, and ruin the surface.

If your pieces are heavily tarnished and you don’t have the time to clean them, please take them to Ngoc Tuan Silver. Very old, fragile, or valuable pieces should also be cleaned by a professional. We maintains a very high standard on quality control over its products and commits to repair or replace manufacturing faults free.

3. How to Find Your Ring Size

Choosing a ring size by measuring your finger

- Cut a strip of paper or a piece of string.The paper strip should be approximately 1/2" wide, and 5" long.

- Wrap the paper or string around the finger to be sized.Slide the paper or string up to the knuckle, as the ring must be sized large enough to able to slip off and on, over the knuckle.

- Use a pen to mark the string or paper where the long end overlaps

- Measure the mark from the end of the length of paper or string with a ruler.Use the metric side for more accurate sizing.

- Locate your ring size by locating your measurement on the printed chart.If the measurement falls in between two sizes, it is recommended that you choose the larger size.

Tips to ensure an accurate measurement:

- Avoid measuring cold finger; as cold finger are smaller then warm finger.

- Measure your finger in warm temperatures at the end of day; this will be when your finger is at its largest.

- If your knuckle is much larger than the base of your finger, make sure and measure both the base of your finger as well as your knuckle and select a size between the two to allow enough room to comfortably slip over your knuckle.

- For a wider band (larger than 6 mm), select one size large than what your actual ring size is, wider band take up more space on the finger.

Tips for buying the ring as a surprise

Ask your significant other’s friend or mother if they know her finger size.

Borrow one of your significant other’s ring (from the correct finger) and use the ring measurements above to determine its size.

To make sure, please go to the Ngoc Tuan stores nearest. We will let you know your exactly ring size by a ring sizer set.
