Diamond jewelry purchased from N.J. Diamonds is backed by complimentary lifetime service. This ongoing care helps keep your ring looking its best and gives our jewelers regular opportunities to spot wear before it becomes a larger problem.
What complimentary lifetime service includes
- Professional cleaning and polishing
- Inspection of prongs, mountings, and settings
- Checking stones for looseness
- Rhodium finishing for qualifying white-gold rings purchased from us
We recommend bringing frequently worn jewelry in for routine inspection and cleaning several times a year. Regular visits are especially helpful for engagement rings and other pieces worn every day, because prongs and settings can gradually wear or catch on clothing.

Routine service is different from repair
Complimentary maintenance does not mean every future repair or replacement is automatically free. Damage, worn or broken parts, missing stones, sizing changes, and other repair work may require a separate estimate. Our team will inspect the piece and explain any recommended work before proceeding.
Why regular inspections matter
A loose stone may not be obvious during normal wear. An inspection can reveal a thin prong, movement in a setting, or other signs of wear early. Cleaning also removes buildup that can hide small problems and dull the appearance of diamonds and gemstones.
