Diamonds lose their fire mainly because oils and lotion collect behind the stone, blocking the light. A soft wash fixes it.

A convertible or jacket earring is really two pieces. Take a detachable design apart before cleaning so water and soap reach the surfaces that normally sit hidden against each other.

Clean the stud and the detachable piece on their own, dry both fully, and only reassemble once there's no trapped moisture.

Cleaning is the natural moment to inspect. Press each back fully onto its post and feel whether it holds. A back that spins freely or slips off easily is telling you it needs attention.

Look at the little prongs or channel holding the stone. If anything feels loose or catches on fabric, stop wearing the earring until it's checked - a secure setting is what keeps a stone where it belongs.

A princess cut is square, and its four corners are the most exposed point of the stone. They're durable in normal wear but vulnerable to a sharp knock against a hard surface.

Two habits help: avoid banging the earrings against door frames, sinks and counters, and store them where the corners aren't pressing against other jewellery.

Home care handles the everyday; a jeweler handles the rest. Book a professional clean and check if a back won't stay tight, a prong lifts, a stone feels loose, or the sparkle doesn't return after washing.

A periodic setting check is inexpensive insurance for a piece you plan to keep.

Diamonds are hard enough to scratch other stones and metals, so give studs their own soft pouch or a lined compartment rather than a shared dish. Keep detachable parts together so a set stays complete.

Dry, separate, and cushioned - that's the whole rule.
