Care, warranty and repairs
A diamond is hard. The setting around it needs looking after.
From the CTJ Jewellery team, led by founder Greg Ward
Diamond is the hardest natural material, but claws and settings wear over time. A few habits, and a professional inspection at least once every 12 months, keep your jewellery secure and looking its best.
Everyday care
Cleaning
Warm water, a drop of mild soap and a soft brush. Rinse and dry.
Storage
Keep pieces apart. Diamonds can scratch other stones and each other.
Inspection
Bring your piece in at least once every 12 months so our jeweller can check the setting, claws and diamonds.
Take it off
For the gym, gardening and heavy work.
Complimentary aftercare
For jewellery purchased from CTJ Jewellery:
- Complimentary ultrasonic cleaning, with a jeweller’s visual inspection under magnification.
- Polishing and rhodium plating for engagement rings purchased from CTJ, free of charge once before your wedding. Booking required.
