How to care for lab-grown diamond jewellery
Clean lab-grown diamond jewellery in warm water with a drop of mild dish soap and a soft brush, dry with a lint-free cloth, and store pieces separately. Lab-grown diamonds are as hard as mined diamonds, so care is identical; the metal and setting need the attention.

Soak the piece in warm water with mild dish soap for a few minutes, brush gently behind the stone where lotion and soap scum collect, rinse and pat dry. That restores most lost sparkle.
Avoid toothpaste and abrasive cleaners; they scratch gold. Ultrasonic cleaners are safe for most diamond solitaires but not for fracture-filled stones or loose settings.
What to avoid
Chlorine and bleach attack gold alloys, so remove rings before pools and cleaning. Take rings off for gym, gardening and manual work: diamonds are hard, but prongs are small pieces of metal.
Put jewellery on after perfume, hairspray and lotion, not before; film on the stone dulls its light return.
Storage
Store each piece separately in a soft pouch or lined box. Diamonds scratch other jewellery, and gold chains tangle around ring settings.
Keep certificates and invoices with the piece's records, not in the jewellery box.
When to get a check
Have prongs and settings checked by a jeweller once a year, or immediately if the stone moves or a prong snags on fabric. A loose stone caught early is a tightening, not a loss.
White gold may want fresh rhodium plating every year or two to keep its bright white finish.
