We want you to enjoy your new jewellery worry-free. We stand behind the quality of our jewellery and offer a warranty on all items.
- Conscious collection
We offer a two-year warranty on our Conscious Collection from the date of purchase. This includes a certificate of authenticity. We will take care of your jewellery if damage occurs to the material or craftsmanship. We work with top manufacturers to create semi-handmade, responsibly produced pieces that are made to last. We have confidence in the quality of our products and therefore offer a two-year warranty.
This also means that the warranty does not cover lost items, scratches caused by normal use (such as a bent ring or broken chain), improper use or storage of your product, or any modification to your product carried out by a third party outside AVJ.
- Vintage collection
We offer a three-month warranty on our Vintage Collection from the date of purchase, exceeding the standard offered by other vintage shops. This is because we thoroughly inspect each item before offering it for sale. Unfortunately, we cannot offer a longer warranty because we are not the maker of the jewellery.

TIPS & TRICKS
- If you are between two sizes, choose the larger size.
- Measure your ring size at the end of the day, as your fingers are largest then.
- The wider a ring band, the tighter it fits. If you choose a wide ring, go for half a size larger.
- Do not measure your ring size if your hands are very cold. This can cause you to measure a ring size that is too small.
- Alcohol and salt can cause your fingers to swell. Try measuring your ring size at a different time.
