 Know when you can resize rings using the International ring size chart.

Many jewellers will happily adjust a ring two sizes in either direction.
However, any extreme adjustments can noticeably impact the look and structure of your jewellery.
Increasing the size of a gold or silver ring generally involves the gentle hammering of the ring around a sizing shaft. This causes the shank of the ring to thin slightly.
Note that in some rings, the end result will not be perfectly round.
If you need to increase a ring more than one full size or to adjust a ring with stones, your jeweller might prefer to make an incision in the ring in order to remove or insert extra metal.
Although this adjustment may leave a visible seam or an invisible weak point, a professional jeweller should be able to position any flaws out of sight.
