Speaking of
@Hiker4life's earring adjustments...
I am obsessed with adjustments being the exact same; hence, I want to share a new tool VCA is using for earring adjustments.
First, some background...
I have three VCA earrings. I have adjusted all my earrings by loosening the tension and replacing the post with a thinner post. I like to wear my earrings loose as I have very sensitive ears. Hence, I like a tiny bit of air space between the earring and my ears to allow them to breathe a bit (the earrings will not fall off due to the closed French clips).
The first two earrings were adjusted perfectly. They are loose, but they hang nice. However, the third earring always flopped a bit. I assumed all the earrings were adjusted to the same tension as that is how I requested it. Hence, I assumed the slight flop was due to the design of the earring. It's not a biggie for me as my top priority is that all my earrings are adjusted to the exact same tension, regardless of how they hang on my ears.
One day, I used my micrometer to measure the tension on all three VCA earrings to make sure all earrings were exact. Horrors, but the earring that slightly flopped was 0.5mm looser! Well... that 0.5mm annoyed me as I like things to be exact.

I told my SA my earrings are not the same... I need them fixed please!


He said the problem has been that SAs measure and give direction differently (e.g. "loosen posts"... what does that mean? how loose?), they are not experts at measuring, and the result has not been consistent. Therefore, VCA often has re-dos for earring tension adjustment.
He then said there is an earring tension measuring tool being piloted in NYC. This tool measures the tension opening in earrings, so once you have them measure an earring that fits you perfectly, they can adjust all earrings to the exact same tension. For those who have one, the tool is basically a micrometer caliper, but it's for VCA earrings so the start/end points referenced are the same for anyone who measures.
Well of course, I had to bring in all my earrings as I am sure the way I measure on my micrometer is different then how VCA measures using their micrometer!
I brought my earrings in, and I am happy to report, I now have in my profile that my perfect earring tension should be set to a 3.5mm opening.
It's great they have this tool for consistency vs. just noting in the instructions "loosen posts" only for the bench jeweler to now have to guess how loose. The SA said VCA is piloting this in NYC, but they hope to bring it to other boutiques to minimize the number of earring adjustment re-dos.
I just wanted to share this as FYI in case anyone has concerns about needing earring adjustments. You can get a precise measurement and in the future, just tell your SA the exact tension you prefer.
