Returns & exchanges
Most Infinite Gems pieces are made to order and personalised for you — metal, carat, and size are chosen at purchase. For that reason, completed made-to-order jewellery is generally final sale once production has begun.
If something arrives damaged, incorrect, or not as described, contact us promptly with your order number and photos. We will review the issue carefully and arrange a repair, remake, or other remedy where appropriate.
For stock or non-personalised items (when available), we consider exchange or return requests within a reasonable window if the piece is unused and in original condition. We do not use countdown timers or false scarcity to pressure a decision.
Email info@infinitegemshk.com or message us via the store — we respond personally. Full details: Returns & refund policy.
Lifetime Warranty
Every piece leaves our Hong Kong atelier only after a final inspection, and we stand behind that work for as long as you own it. Your lifetime warranty covers:
| What is covered |
|---|
| 1.Defects in materials or workmanship |
| 2.Tightening or replacement of a diamond that loosens or is lost through a fault in the setting |
| 3.Prong repair and re-tipping as they soften with everyday wear |
| 4.Clasps, chains and settings that fail because of a production flaw |
| 5.Professional polishing to bring back the original finish |
All of the above are carried out free of charge for the lifetime of your jewellery, provided the issue arises from ordinary wear rather than accidental damage, loss, or alteration by another jeweller.
Where the issue is a manufacturing defect reported within the first year, we cover shipment charges both ways. For everything else, shipment charges to and from our atelier are at your cost.
To make a claim, contact our team with your order details. For full details, please refer to our Warranty Policy.
Payment & Instalments
You can pay in full by card or by bank transfer. Bank transfer carries a 4% discount — select it at checkout to see the saving applied.
If you would rather pay in stages, we arrange a 30% deposit plan on any piece, with the balance due before your order is dispatched. Contact our team and we will set it up for you.

Ring size guide
Finding a comfortable ring size is simple.
How to measure at home
1. Wrap a thin strip of paper or soft string around the base of your finger.
2. Mark where the ends meet, then measure the length in millimetres — that is your circumference.
3. Match the millimetre measurement to the chart below (US / HK common sizes).
If you are between sizes, choose the larger size for comfort, especially for wider bands.
Prefer a precise fit? Bring a well-fitting ring of similar width to a jeweller, or message us and we will guide you gently through the process.
