Lifetime Warranty
Last updated 5 October 2026
Every piece of jewellery bought from Diamond Hub comes with our lifetime warranty. Diamond Hub is the sister company of Hispek Diamonds. Both are trading names of Nascoglobal Limited and share the same craftsmanship standards and aftercare.
What the warranty covers
For the lifetime of the piece, we will carry out the following free of charge:
- Manufacturing defects: free repair or, where repair isn't possible, replacement.
- Stone tightening: checking and re-securing all diamonds and gemstones in their settings.
- Claw re-tipping: rebuilding worn claws that hold your stones.
- Professional polishing: restoring the finish of the metal.
We recommend bringing your piece in for a check once a year so we can spot wear on claws and settings early.
What the warranty does not cover
- Accidental damage, such as chips, cracks, or settings bent or distorted by impact.
- Stones lost as a result of impact, misuse or accidental damage.
- Damage from chemicals, such as bleach, chlorine or household cleaning products.
- Normal wear and scratching of metal surfaces.
- Loss or theft of the piece.
- Pieces that have been altered, repaired or resized by anyone other than Diamond Hub or Hispek Diamonds.
Because the warranty doesn't cover loss, theft or accidental damage, we strongly recommend insuring your jewellery. We can provide a valuation certificate for insurance purposes; just ask at the time of purchase.
How to use your warranty
- Contact us on WhatsApp or at sales@diamondhub.co.uk with your order number or proof of purchase.
- Bring the piece to our Leicester or London (Edgware) showroom, or post it to us using a fully insured, tracked service.
- We'll inspect it, carry out any covered work and return it to you, usually within 5–7 working days.
If we find damage that isn't covered, we'll give you a quote before doing any work.
Your statutory rights
This warranty is in addition to your legal rights as a consumer and does not affect them. It forms part of our Terms & Conditions.
