Q&A with a Jeweler [Allergic Reactions Edition]

Mom Pic (Resized)Peggy Woon is a GIA-accredited jeweler; now a retiree, she was in the jewelry industry for more than 30 years. For 28 years, she and her business partner co-owned the Silver Lining Jewelry store in Oakland, Calif.  Today, she spends her time spoiling 3 grandchildren and 2 German Shepherds, as well as volunteering with local non-profits. Unable to stay away from her first passion, she can also be found working the jewelry counter at the Oakland Museum of California’s White Elephant Sale and occasionally at Given Gold Jewelers on Piedmont Avenue.


When I was growing up, I’d often visit my mother at her jewelry shop in Oakland where I had the opportunity to watch her speak with customers about what pieces were the best fit for their specific needs; how to wear and repair items; and – once in awhile – I’d hear her speak about how to remedy a potential allergic reaction. Today, we’re sharing a few FAQs about allergic reactions to jewelry that came up over the years.

If someone is having an allergic reaction to a piece of jewelry, e.g., an itchy neck or ears, what do you think is the cause? 
Sometimes it’s the metal, but there are cases where it’s something else. For example, one of my contacts said his stainless steel necklace was making his chest itch, but it turned out that it was the engraving on the piece, not the metal itself.

If someone wants to continue wearing a piece of jewelry that’s irritating them, what do you recommend? 
Many times, the itchiness goes away if you coat the metal with a clear coat of nail polish, which serves as a barrier against the skin. Of course, the polish will wear away over time, so you’d need to reapply the polish once in awhile.

What types of metals seem to cause the most allergic reaction?
Usually metals that are mixed with more nickel tend to irritate people. For example, gold-plated pieces or sometimes sterling silver can be mixed with nickel.

We hope you found this information helpful. If you have any questions that you’d like Peggy to answer in a future Q&A, please leave a comment below.

Q&A with a Jeweler [Glittering Gold Edition]

What is the difference between 24k, 18k and 14k gold? 
When it is mined, it’s 24k solid gold. To make it into jewelry, they have to mix in different alloys to maintain hardness.

18k gold is 75 percent pure (that’s why they stamp it 750) plus 25 percent other alloys to make it hard enough to make it into jewelry.

14k is 525 parts gold and 475 parts different alloys.

If someone wanted to buy a gold piece of jewelry, would you recommend they not get 24k gold because it’s too soft?
24k is really malleable, so unless it’s a really thick piece of jewelry to make it very strong, then it will bend. If you were to buy a thick 24k ring, for instance, it will conform to the shape of your finger.

When you’re shopping for gold jewelry for yourself, what do you typically buy? 
I mostly buy 14k. With 18k you really cannot see the difference, it’s just that you’d know the difference. Some people like having more pure pieces in their collection, but to the general onlooker, no one will know if it’s 14k or 18k.

What does ‘gold filled’ or ‘gold plated’ mean? 
Gold filled is alloy mixed with gold to make it stronger. Usually, it will turn to a shade that’s less shiny than 14k. Typically they’ll do a flash coating of 14k on the outside to give it a nice 14k look, but that will wear away over time. Overall, it will stay a gold color, but it will not be as pretty of a color as what you’d get with 14k.

Gold plated means they’ve coated another metal, such as sterling or brass, with a coat of gold. It will wear off with time and the metal on the inside will show.

Q&A with a Jeweler [‘Real or Fake?’ Edition]

How can you tell if a piece of Silver or Gold is real? If silver is stamped 925, that’s the international code. If it sticks to a magnet, it’s not all silver; it’s some other metal. As for gold, you should also look for stamping; e.g.: if you see 565, 14k, 750, 18k or 24k, then that’s a good indicator that’s it’s real, but not a certainty.

925

What about Pearls? Rub pearls together. If it has a gritty feeling, they’re usually real. If it’s super smooth, they’re most likely not real. [If you only have 1 pearl to test, try rubbing it against your tooth to check the texture.]

Fine Gem Stones? They might be real, but could be color-enhanced by dye injection. This is hard to figure out for the untrained eye. I’ve looked at enough stones, though, that I can get a sense for whether they’re dyed, usually by noticing if the color is too even (no striations) or if it has a fake glass look to it.

Diamonds? At home, you can try to look at the stone closely for carbon and other natural flaws. If it looks too good to be true, it may not be real. This is very difficult to do with the human eye, though. Many jewelers have instruments that can be used to detect carbon in real diamonds. The invention of moissanite (a simulant) complicated things a bit because it can trick some diamond testers. While moissanite is more expensive than a cubic zirconia, it’s not as expensive as a real diamond. For instance, a moissanite 1 karat might be US$800 vs. US$5,000 for a real 1 karat diamond. Today, though, there are tools that can test for moissanite versus a real diamond.

Fine Watches, such as a Rolex? Some watch makers or repair experts can verify a watch by checking the serial numbers. In the case of a Rolex, oftentimes a consumer can look at the watch face and see if the hands have a smooth sweep. If it’s tick-tick-ticking along, that’s not a Rolex. A real Rolex will have hands that appear to glide. Also, if there’s a battery, that’s usually not a real Rolex; most Rolex watches are automatic.
When in doubt, you can bring your pieces to an expert who has instruments that can be used to probe the material to check the authenticity and integrity of the jewelry.
