First, you should take your one carat diamond ring to a jeweler once a year. Have him check the mountings and prongs that hold your diamond in place. Have him make any needed repairs. This will prevent your diamond from falling out of its setting and becoming lost.
One carat diamond ring jewelry that is not being worn, or diamonds that are loose should be stored in a fabric lined jewel case, or in a jewelry box where it can be kept separate from other jewelry. Each piece should have its own compartment. This will keep diamonds from becoming scratched, and it will also keep your diamond from scratching other jewelry as well.
Remove your one carat diamond ring when doing physical work. One carat diamond rings can be chipped and scratched easily. Also avoid allowing your one carat diamond ring to come into contact with bleach or other household cleansers – this can damage or change the color of the
settings and mountings, and it may even irreversibly change the color of the one carat diamond ring!
