-Jewelry with gems: please educate yourself about your desired stones. Some stones have characteristics you need to consider before you go ahead with your order.
Find out how your desired stone will react to excessive sun, chemicals, showering, and labor-intensive activities, and then make your decision.
-Once per year or better once per 6 months you'll need to inspect your rings (gold is a soft metal and with everyday wear, it might get damaged, which may cause stone loss, metal breaks, etc.).
-Silver jewelry with rhodium cover and gold plating: in a while silver rings might get tarnished even with a gold cover. You can clean it with steam at your local jewelry repair. DON'T try to clean it with any hard brushes, you might damage covering.
