The Exciting World of Jewelry Cleaning

Sharon Zimmerman

What’s the Best Way to Clean Jewelry?

You want your jewelry to last you a long time, and so do I. A lot of heart and soul go into each piece and while some wear and tear are normal over time, treating your jewelry and giving it a little TLC can keep it looking great for a lifetime. 

The Basics Don'ts

Avoid wearing while swimming, working out (yes, even yoga), showering, gardening or when working with chemicals. All of these activities can stress your jewelry, scratch it, bend it or just generally gunk it up (ew).

Cleaning Oxidized Silver Jewelry

Oxidized silver has been given a surface treatment to create a dark black color. Over time, this color may fade to bright silver and is considered normal wear. Never fear though, this blackening can be brought back simply and affordably. Contact me if you would like the oxidized patina restored to your Sharon Z Jewelry piece - info@sharonzjewelry.com 

Storage

We know that you want to wear your Sharon Z Jewelry piece all the time, but when you aren’t wearing it, we suggest storing it in the box that it came in or even better, in a tiny plastic bag with an anti-tarnish strip.  The plastic bag trick works especially well for silver.

Eco-Friendly Tarnish Removal

Fun Science Project Alert!

Silver jewelry has a great luster and bright, white color, but over time, exposure to moisture and air can cause tarnish.  Here is a fast, cheap, easy, fun and eco-friendly way to restore your silver jewelry to a bright shine.

  • Boil water

  • Place a piece of tin foil in a heatproof bowl

  • Place jewelry on top of foil

  • Sprinkle baking soda and a pinch of salt over the jewelry

  • Pour boiling water over the jewelry and foil

  • The mixture will bubble (like you're a witch standing over a bubbling cauldron) for a moment and then your silver jewelry will be bright again.

  • Careful when removing jewelry-it will be very hot! (This seems obvious, but my lawyers recommended that I tell you this.)

  • Rinse with cool water

This method is safe for many stones, except for turquoise and opals.  Also, be advised that while pearls will be fine in this process, the epoxy that often holds them in place might come loose due to the heat.

PS - this works great on gold that has discolored too!

5 Ways to Find Out Her (or His) Ring Size On the Sly

Sharon Zimmerman

You're in love, you know you want to get married and you’re ready to propose. So you run out to get a ring, but how do you know that it’s going to fit them? A ring, unlike earrings and necklaces, isn't a one-size-fits-all piece of jewelry, so getting the size at least kinda sorta close to right is important.  Here are a few helpful hints for getting things right the first time.

Option #1 - Find a ring that he or she wears on their ring finger

This is probably the easiest shortcut to finding out their ring size, but it also assumes that your beloved wears a ring on their ring finger. Some women don’t wear anything on that finger before engagement or marriage out of tradition. Just keep in mind that there can be a significant size difference between the right hand and the left hand, so if you find a ring that they wear on their right hand, it may not be exactly the right size for their left hand.

Option #2 - Ask her friends.

There is always a chance that she’s dropped hints. Big hints. And by hints, I mean that she may have actually told her best friend (or sister, or Mom) what her ring size is. So...not really a hint. More like a giant clue that she’s left for you to find. And a pretty easy-to-find clue at that.

 Option #3 - Find out while they are sleeping

This will assume that you have super stealthy ninja-like skills. Your first step is to acquire a finger sizer. Then, while they are asleep, carefully and without being detected slip the sizer onto their left hand ring finger. Et Voilà! Ring size!*

Option #4 - Order a placeholder ring

Have they already decided which designer they’d like a ring from**? If so, then it's a good bet that your future betrothed would like something else from that same designer. Ordering something smaller and less formal is a lot less risky and can create a sweet memory for the two of you. Then you can plan together which "official" ring to get. It could even be a ring that can stack with their eventual engagement and wedding rings.

Option #5 - Well, you could just ask

Sure, it’s not exactly romantic, but maybe you guys are a couple of rule-breakers anyway. Or maybe you are both super-communicative.  Either way, if you talk openly about your future together, asking for their ring size won’t be a downer. Besides, you don’t have to tell them when you’re planning to propose.

*If they wake up and you get caught, just tell them that you were trying to hold their hand.

**OK, so let’s back up for a moment and say that you have no idea what kind of ring they would like. The best place to do your secret spy research is on Pinterest. Take a look at their boards and see what kinds of jewelry they pin. There is a great chance that they already have a board totally dedicated specifically to engagement rings. And when in doubt, ask their friends.

Why is my skin turning black under my rings?

Sharon Zimmerman

Hint: It's not an allergy.

A few years ago, I thought I was developing an allergy to silver and gold.  Almost overnight, my skin was turning black underneath my rings and I couldn't explain it. The answer?  Science!

At about the same time that my skin started turning colors, I had started using a mineral sunscreen* containing zinc oxide.  Zinc Oxide, in its non-nano state, is a fantastic and safe sun-blocking agent as well as a common ingredient in many cosmetics. I am pretty obsessed with my skin care (though you wouldn't believe it if you saw my hands. Ah well, such is the jeweler's life). Zinc oxide is also, as it turns out, a very mild abrasive.  Veeeery mild. But gold and silver are soft metals, so the mild abrasive in my sunscreen was actually rubbing off minuscule particles of metal from my rings and these particles transferred to my skin and appeared black.

My solution?  Well, I wasn't going to discontinue using my sunscreen nor would I stop wearing rings and the problem goes away when I, you know, wash. My. Hands. I also wait to put on rings until after I've applied the sunscreen and washed my hands. Sometimes the simple solutions are the best. And don't forget to clean your jewelry to get rid of any residual make up, soap, sunscreen, etc. Here is our Step-by-Step guide to safely cleaning and caring for your jewelry.

And now, please resume wearing all of the rings.
