Antique! But not old



Gold jewelry never goes out of style, and for good reason, because gold is as wearer-friendly as it is beautiful. Pure gold doesn't react with other elements to create tarnish, the residue that accumulates on some metals before transferring to your skin as a stain. Sometimes people have allergy or staining problems with metals that are combined with gold, but the gold itself is rarely a problem. Gold can be worked into nearly any shape, including tiny strands that do not break easily. One ounce of gold can even be hammered into an ultra thin sheet that's ten feet square. Gold can be manipulated nearly any way the artisan desires.

Yellow Gold

White Gold
White Gold has extra silver and nickel added. white gold is 14kt white gold and that means that it is 59.3% gold and a mixture of other alloys making up the rest of the gold.

Two Tone Gold
Refers to the use of more than one color of gold in making an item of gold jewelry.Two-tone gold is white and yellow gold in combination in the same bracelet.

Tri colour Gold
other metals are mixed with the gold to create tri-color gold. This doesn't have to mean it's worthless. Tri-color gold jewelry is made up of
1 yellow gold ('regular' gold - what we normally think of as gold)
2 white gold
3 rose gold


Examine the gold item that you would like to test. Look it over carefully for any identifying marks, such as 10k, 14k, 18k and so forth. This is because the test needle and acidic solution will vary according to how many karats (k) the gold is, so if you can identify what it is marked as, you will have the most logical place to start.

Pick up the touchstone and the test needle that corresponds to the marking on the gold. For example, if you want to test the purity of an item that is marked as 14 karat, you will want to use a 14 karat test needle. Because the test needle is from a known source that is proven to be 14 karat, it can be used for comparative analysis.

Scratch the test needle against the touchstone. It should be a firm scratch, but at the same time, you should not scratch like mad across the entire surface of the touchstone. That will only result in needing to buy a new touchstone every time you test the purity of gold. Just a small, firm scratch with the test needle is all that is required.

Use the gold item you are testing to make a second scratch, next to the one that was made with the test needle. The result is that your test stone now has two scratches. Ideally, these scratches will be located side-by-side for easier analysis.

Use the acid solution that corresponds to the test needle. For example, if you are testing with a 14-karat test needle, then use the 14-karat gold solution, or use an 18-karat solution if you used the 18-karat test needle, etc. Because each acid solution is developed to work with a specific gold purity level, it is important to use the right acid. Simply drip one or two drops on the scratches you made with your needle and the test item.

Analyze the results. The scratches should appear to change color in reaction to the acid that has been dripped on them. If the color of the scratch from the test needle is the same as the color generated by the scratch from the test item, then you have a positive identification. If the colors do not match, then repeat the process using a different test needle and acidic solution.


Don't wear your gold jewelry while bathing or cleaning. Soap won't harm gold, but it will leave a filmy residue that will coat karat gold jewelry, causing it to appear less lustrous and dingy. If you prevent the film from forming, it will be easier to keep your jewelry beautiful and will reduce cleaning time and effort.

Avoid chlorine! Don't wear gold jewelry in the pool or hot tub or when using chlorine bleach or cleaners. Chlorine reacts with gold, particularly at high temperatures. Exposure to chlorine can permanently damage and discolor your gold jewelry.

Use a chamois cloth to clean gold jewelry. A chamois cloth is a gentle, safe material for returning the luster to your jewelry.

Avoid storing or otherwise exposing gold jewelry to hard, abrasive materials. Gold is a very soft metal, easily scratched even by rubbing against other jewelry.


Tarnish can be removed with a commercial jewelry cleaner or with soap and water with a few drops of ammonia. Brush the cleaning solution into the gold with a small brush (a toothbrush works well). After you have finished cleaning, simply rinse the gold with lukewarm water and allow it to dry.

Grease can be removed from gold by dipping it into ordinary rubbing alcohol.

Ultrasonic cleaners may be appropriate for some gold jewelry. Ask a jeweler to advise you before using this method, since certain pieces can be damaged by this cleaning method.
