FAQ's

When resizing we recommend either going up or down two sizes to minimise the risk of damage. If you go any further than 2 sizes up or down, the risk of damaging the ring or affecting the diamond/gemstone massively increases.

There are many factors that affect the resizing of your ring and depending on the design, there may be instances where resizing may not be possible. If your ring is set on a full eternity band, it’s likely that it’s unable to be resized as there is no bare metal for the jeweller to work with. If your ring is set on a plain band, providing there is enough material to work with resizing is a fairly easy process. Here at Diamonds Factory, we also offer complimentary 30-day free resizing too.

If your ring is unable to be resized, there are plenty of other options to consider so don’t panic. The first option is of course to have it remade; however, this may not necessarily be in your budget and luckily there are much more affordable options to consider. One option is to purchase a new ring mount and have your diamond/gemstone added onto this instead, saving you money on buying a new precious stone. An even cheaper option is to add a small sizing bar or adjuster at the bottom of your ring.

Upon receiving your ring, we aim to get resizing done with 10-14 days. However, it’s important to note that depending on your ring design, this may take longer. Resizing cannot be done in store, and items need to be sent directly to our warehouse where our skilled craftsmen will resize your ring.

Rings can be resized up to 2-4 times. It’s important to note that every time you resize a ring you are weakening its structure slightly, which is why we recommend trying to get your resizing right on the first round.
