How can lab diamonds be maintained and cared for after purchase?
Lab diamonds can be maintained in the same way as natural diamonds: clean them regularly with mild soapy water and a soft brush, store them separately to prevent scratching, and arrange professional inspections to check the setting and secure the stone. Remove diamond jewellery before activities involving chemicals, impact or prolonged exposure to lotions and cosmetics, and seek expert advice if the stone becomes loose or damaged.
Lab-grown diamonds are real diamonds with the same hardness, crystal structure and resistance to everyday wear as natural diamonds, so they should be cared for in much the same way. Regular gentle cleaning, careful storage, protection from impact and periodic professional inspections will help preserve both the diamond’s brilliance and the security of its setting.
Clean the diamond jewellery regularly
Skin oils, cosmetics, hand cream and everyday dust can accumulate on the diamond and make it appear dull. For routine cleaning, place the jewellery in warm water with a small amount of mild washing-up liquid. Leave it to soak briefly, then use a clean, soft-bristled brush to gently clean around the stone, underneath the setting and between the claws.
Rinse the jewellery thoroughly in clean water and dry it with a soft, lint-free cloth. Always clean over a bowl or a securely closed sink rather than over an open plughole. A soft jewellery cloth can be used for the metal, but avoid abrasive cloths and household paper products that may leave fibres or cause fine surface marks.
Use caution with cleaning products
The diamond itself is highly resistant to scratching, but the surrounding metal and setting may be affected by harsh substances. Do not use bleach, chlorine, abrasive powders, strong solvents or unapproved jewellery cleaners. These products can discolour precious metals, weaken some settings or damage other gemstones in the same piece.
Remove rings and other diamond jewellery before swimming in chlorinated water, using household cleaning products, gardening, applying beauty products or taking part in activities where the piece may be exposed to impact. Hand sanitiser and lotions will not normally damage a lab-grown diamond, but repeated residue can reduce its sparkle and may affect the finish of some metals. Allow creams and products to absorb before putting the jewellery back on.
Be careful with ultrasonic and steam cleaning
Ultrasonic cleaners and steam cleaners can provide effective professional results, but they are not suitable for every item. Vibrations may loosen a stone that is already insecure, while heat and pressure can be unsuitable for certain settings, delicate construction or treated gemstones alongside the diamond. A jeweller should assess the piece before these methods are used. Gentle home cleaning is the safer choice unless professional cleaning has been recommended for your specific jewellery.
Protect the setting as well as the diamond
A lab-grown diamond is difficult to scratch, but it can still chip if it receives a sharp blow at a vulnerable edge or point. In everyday use, the setting is usually more likely to require attention than the diamond itself. Check the jewellery occasionally for signs such as:
- a claw that looks bent, worn or lower than the others;
- a stone that moves, clicks or feels loose when touched gently;
- snagging on clothing, which can indicate a damaged claw;
- gaps, cracks or distortion in the mount;
- noticeable wear beneath the ring or around the setting.
Do not continue wearing a piece if the diamond appears loose or the setting has been damaged. Keep it safely in a soft box or pouch and arrange an inspection. Attempting to tighten a claw or reshape a setting at home can cause further damage or allow the stone to fall out.
Remove jewellery for high-impact activities
Take off diamond rings before lifting heavy objects, exercising with equipment, playing contact sports, carrying out DIY or doing manual work. Repeated knocks can bend the setting even when the diamond itself remains undamaged. Rings can also become trapped or distorted when pressure is applied from the side, so avoid wearing them for activities that place stress on the band or mount.
It is also sensible to remove jewellery before bathing or sleeping. This reduces exposure to product residue and prevents the setting catching on fabric or bedding. Keep the piece in a safe place rather than leaving it beside a sink or on a bathroom surface.
Store each piece separately
Store lab diamond jewellery in a lined jewellery box, a soft pouch or a compartment where it cannot rub against other pieces. Diamonds can scratch other gemstones and precious metals, while jewellery rubbing together can cause fine marks and bent claws. Keep earrings, pendants and rings separated, particularly when they have exposed edges or fine settings.
For valuable pieces, choose a dry storage location away from excessive heat, humidity and direct sunlight. Keep any diamond report, purchase documentation, valuation and insurance records in a separate secure place, and update records if the jewellery is remodelled or the setting is substantially altered.
Arrange professional cleaning and inspections
A professional inspection can identify wear that is difficult to see at home. The jeweller can check the claws, setting, shank, soldered joints and the diamond’s security, then clean the piece using an appropriate method. The right frequency depends on how often the jewellery is worn, the design and the type of setting. Frequently worn engagement and wedding rings benefit from regular checks, while occasional pieces may need attention less often.
Professional care is particularly important for delicate settings, pavé or halo designs, older jewellery and pieces worn during demanding work. If the jewellery has been knocked, dropped or caught on clothing, have it checked even if there is no obvious damage.
What to do if a lab diamond is damaged
Although lab-grown diamonds have the same durability as natural diamonds, they are not indestructible. If the stone chips, becomes loose or appears cloudy after an impact, stop wearing the jewellery and have it examined. Do not try to polish, glue or reset the diamond yourself. An expert can determine whether the issue concerns the stone, the setting or surface residue and advise on cleaning, repair, resetting or replacement where appropriate.
With gentle cleaning, sensible protection and proper aftercare, a lab-grown diamond can remain bright and securely set for many years. If you are unsure which cleaning method is suitable for a particular design, professional advice is preferable to using a strong product or cleaning device without checking first.
Professional inspections help maintain lab diamond jewellery by checking the security of the setting as well as the condition of the diamond. Although a lab-grown diamond has the same durability as a natural diamond, claws, bezels, soldered joints and the surrounding metal can wear or become loose through everyday use.
Arrange an inspection if the stone moves, clicks, catches on clothing or appears lower than usual in its setting. It is also sensible to have frequently worn rings checked as part of their routine aftercare, particularly if they have a delicate pavé or halo design. If damage is suspected, stop wearing the jewellery and keep it in a soft pouch until it can be assessed. Do not attempt to tighten claws, reshape the mount or reset the diamond at home, as this may cause further damage or allow the stone to fall out.
