Zinc is added to silver, gold and platinum, to make it hard enough to handle everyday wear and tear. All precious metals are too soft to not get dents and dings. Twenty four carat gold is the most gold there can be for jewelry, but it's not pure. 100% gold is so soft that it has been pounded as thin as tin foil by hand.
I'm glad things are so good that you feel your husband would agree to a new ring set, even though it wouldn't solve your skin problem. I also get dry hands in winter. Is that your problem, too, or is it year round? Have you tried Shea butter for your hands? That's what I plan to try next.
We haven't agreed to what set yet, the one I really like is a bit pricey for our budget, it's a little over 500. But we are trying to compromise lol. It's all year long, I have Dyshidrotic Dermatitis. I'll have to try shea butter, Thanks for the idea :)
