None of us are perfect ! I should admit right now that I have very unattractive hands so I dislike wearing rings, and will usually take them off within an hour or so and abandon them whereever I happen to be sitting.

I do have a few rings that I like (e.g. from the ball range above), but as I don't have a good feel for either comfortable or irritating rings I don't rush to make them. Luckily I have colleagues who will love to make rings for you.

Wedding Ring

If making special ring in gold, make in silver first to be sure of the size.

Stones have to be removed before the metal is heated so it is important to get the size right before the stones are set.

Hopefully less subjective.

For a surprise present

Get an old ring (but one that they still wear) measured by a jeweller.

Remember that different rings fit different fingers and some rings more appropriate on particular fingers.
Naming or numbering your fingers can be different to different people, be sure which finger it is for. I suggest naming as follows : thumb, index, middle, ring, little finger.
