A well-cared-for diamond ring lasts a lifetime. A neglected one accumulates grime, loosens at the prongs, and eventually risks losing the stone. The difference is not a matter of expense, it is a matter of routine. This year-round maintenance calendar walks you through the daily, monthly, quarterly and annual care that keeps a diamond ring in heirloom condition, with practical tips for Singapore's specific climate challenges of high humidity, pollution, and sun.
Why Diamond Rings Need More Care Than People Think
A diamond is the hardest natural material on Earth, but the setting that holds it is not. The 18K gold or platinum prongs that grip the stone can bend, wear thin, or loosen over years of daily wear. The space behind the diamond accumulates lotions, sunscreen, dirt and grease, which dulls the brilliance of the stone and creates a film no amount of casual rinsing will remove.
Singapore adds three specific complications:
- High humidity accelerates the dulling of polished metal and creates more chances for skin oils and lotions to combine with airborne particles
- Urban pollution deposits microscopic grime that becomes lodged behind set stones
- Sun and chlorine exposure from poolside and beach activities can damage the rhodium plating on white gold and contribute to setting wear
This is why a maintenance calendar matters more in Singapore than it might in cooler, drier climates.
Daily Care: What to Do Every Day
The day-to-day habits that protect a diamond ring add up to more than any single annual service.
Take the ring off before
- Showering, washing hands repeatedly, or using harsh soaps. (soap film accumulates behind the stone)
- Applying sunscreen, lotion, or perfume. (always apply these first, then put the ring on)
- Cleaning the house with chemical cleaners or bleach.
- Cooking with raw meat or anything that requires aggressive hand washing afterwards.
- Swimming, particularly in chlorinated pools or salt water.
- Exercising, especially weight training where the ring can be impacted against equipment.
Put the ring on after: Hair products, makeup, lotion, and any wet activity. The general rule is that the ring goes on last and comes off first.
Store the ring properly: In a soft pouch or padded jewellery box when not worn, never loose in a drawer with other pieces where it can scratch or be scratched. Diamonds are hard enough to damage soft 18K gold settings on other pieces.
Weekly Care: The Quick Soak
Once a week, give the ring a brief at-home cleaning to prevent buildup before it becomes a problem.
What you need: warm water, mild dish soap (the unscented kind without moisturisers), a small soft-bristled toothbrush dedicated to jewellery, and a soft lint-free cloth.
The five-minute clean
- Mix a few drops of dish soap with warm water in a small bowl
- Soak the ring for 10 to 15 minutes
- Gently brush around and behind the setting with the soft toothbrush
- Rinse thoroughly under warm running water (with the drain closed, or over a strainer, in case the ring slips)
- Pat dry with the lint-free cloth, paying attention to the area behind the stone where water can accumulate
Avoid at all costs: Bleach, ammonia, chlorine, abrasive cleaners, ultrasonic cleaners without supervision (the vibrations can loosen stones in older settings), or steam cleaners on rings with treated stones or particularly delicate settings.
Monthly Care: The Inspection
Once a month, do a visual inspection of your own ring. This is where you catch problems early.
What to look for
- Prong wear: Are the prongs still grabbing the diamond firmly? Tap the ring gently against your ear; a healthy setting makes a clean, silent feel without rattling
- Prong height: Are all prongs at similar height? A prong that has worn down significantly is a warning sign
- Stone movement: Very gently press the diamond from each side. There should be no movement whatsoever. If you feel any wiggle, get the ring serviced immediately
- Scratches or dents on the band: Minor surface wear is normal and can be polished; deep gouges may need professional reshaping
- Rhodium plating wear on white gold: If the white gold is starting to show a yellowish tint underneath, it is time for re-plating
If anything feels wrong, do not wait. Take the ring to a jeweller for inspection before continuing to wear it.
Quarterly Care: Professional Cleaning
Every three months, take the ring to a professional jeweller for a thorough cleaning. Most established Singapore jewellers, including Poh Heng, offer complimentary cleaning services for pieces purchased from them.
A professional cleaning typically includes:
- Ultrasonic cleaning to remove deep grime from behind the setting.
- Steam cleaning to lift residual film.
- Polishing of the band to remove minor surface scratches.
- A quick visual inspection by the jeweller.
Pieces from the Poh Heng Trust® diamond collection qualify for complimentary in-store cleaning across our Singapore stores. Find your nearest store and book a quarterly service visit.
Bi-Annual Care: The Detailed Inspection
Twice a year, ask the jeweller for a more detailed inspection that goes beyond surface cleaning. This is when prong condition, setting integrity, and any developing structural issues are checked.
What the jeweller is looking for
- Prong wear that needs re-tipping (adding a small amount of new metal to worn prongs)
- Shank thinning on the band, particularly on the underside where rings tend to wear from contact with adjacent fingers
- Any setting movement that indicates the stone needs to be re-secured
- Wear patterns that suggest the ring needs structural reinforcement
Re-tipping prongs is a relatively quick service that prevents the much larger problem of a lost stone. Catching it at the bi-annual check is significantly cheaper and faster than dealing with a loose-stone emergency.
Annual Care: The Full Service
Once a year, plan a complete service for the ring. This is the moment for any work that has been building up across the year.
A full annual service typically covers
- Complete ultrasonic and steam cleaning
- Polishing to restore the band's original finish
- Rhodium re-plating for white gold pieces (if needed)
- Prong inspection and re-tipping if required
- Re-securing of any settings that have loosened
- Verification of stone integrity and certificate matching for GIA-certified diamonds
For engagement rings and high-value diamond pieces, the annual service is also a good time to review your insurance coverage. Diamond prices have generally trended upward, and a piece bought five years ago may need updated coverage.
Two-to-Three Year Care: Rhodium Re-Plating for White Gold
18K white gold pieces have a layer of rhodium plating that gives them their bright white finish. With daily wear, this plating gradually wears off, revealing a slightly yellow tint underneath (the natural colour of the white gold alloy).
Rhodium re-plating is a quick service that restores the bright white finish. Most pieces need it every 1 to 3 years depending on wear frequency. Pieces worn daily, like engagement rings and wedding bands, sit at the more frequent end.
This is one of the reasons 18K rose gold and 18K yellow gold pieces require slightly less maintenance than 18K white gold. The colour in those pieces comes from the alloy itself, not surface plating.
After Major Impact: What to Do
If your ring takes a hard knock, against a doorframe, sports equipment, a fall, or any significant impact, take it off immediately and do not wear it again until a jeweller has inspected it.
Diamond settings can be visibly fine but structurally compromised after impact. A prong can be bent or weakened in ways that are not visible to the naked eye but will fail under normal wear soon after. A quick inspection costs nothing and prevents losing the stone.
A Practical Annual Calendar at a Glance
Here is the year-round maintenance condensed into a calendar you can follow:
- Daily: Take the ring off for water, chemicals, and impact-prone activities
- Weekly: At-home soak and gentle brush clean
- Monthly: Visual inspection at home for prong wear and stone movement
- Quarterly: (Every 3 months): professional cleaning at a jeweller
- Bi-annually (every 6 months): detailed inspection by a jeweller
- Annually: Full service including polishing and insurance review
- Every 1 to 3 years: Rhodium re-plating for white gold pieces
- Immediately: Any inspection after impact, water exposure, or signs of loosening

F. FAQ Section
How often should I clean my diamond ring at home?
Once a week is the right frequency for at-home cleaning. A 10 to 15 minute soak in warm water with mild dish soap, followed by gentle brushing behind the setting and a thorough rinse, prevents buildup before it becomes a problem.
How often should I get my diamond ring professionally serviced?
Quarterly professional cleaning (every 3 months) plus a full annual service. Bi-annual detailed inspections (every 6 months) check for prong wear and setting integrity. Most established Singapore jewellers including Poh Heng offer complimentary cleaning for pieces purchased from them.
Can I use ultrasonic cleaners on my diamond ring?
With caution. Ultrasonic cleaners work well on most modern diamond rings in solid settings, but they can loosen stones in older or more delicate settings, particularly pieces with treated diamonds or fragile pavé work. If in doubt, have the cleaning done professionally rather than at home.
How do I know if my diamond ring needs servicing?
Watch for prong wear (uneven prong heights or visibly thin prongs), any movement when you press the diamond gently from the side, a yellowish tint appearing on white gold (rhodium plating wearing off), or scratches and dullness on the band. Any of these means it's time to service the piece.
Should I take my diamond ring off when sleeping?
Personal preference. Many wearers leave the ring on overnight; others remove it. If you do remove it, store it in a soft pouch or padded jewellery box, never loose in a drawer. The ring is more likely to be damaged by being knocked off the bedside table than by being worn during sleep.
Can I wear my diamond ring in the swimming pool?
No. Chlorine damages the rhodium plating on white gold and can degrade the prong metal over time. Salt water has similar effects. Always remove the ring before swimming, regardless of whether the water looks clean.
How long does rhodium plating last on white gold?
Typically 1 to 3 years depending on how often the ring is worn. Engagement rings worn daily sit at the more frequent end of that range. The rhodium wears off gradually, so you might not notice it for many months; once you see the natural yellowish tint underneath, it's time to re-plate.
What happens if my diamond comes loose?
Stop wearing the ring immediately and take it to a jeweller. A loose diamond means the prongs have worn or bent, which is fixable through re-tipping. Continuing to wear a loose-stone ring risks losing the diamond entirely.
Can a diamond ring be re-sized?
Most diamond rings can be re-sized, though the complexity depends on the setting. Plain bands re-size easily. Eternity bands with stones all the way around are very difficult or impossible to re-size. Discuss re-sizing options with your jeweller at the time of purchase so you understand future flexibility.
