When using a mandrel for ring sizing, do you consider the leading edge of the ring to be the correct size, or where the middle of the ring falls on the mandrel?
I've got a great mandrel that I bought on Amazon, and yesterday I picked my new aquamarine and diamond ring up from the jeweller's in the UK and brought it back to America. I had asked for it to be sized to an American 5, which is a British J and a half. They said they'd look up the measurements for an American 5. The ring size is almost right, but when my hands were cold on the plane I noticed it seemed a bit bigger than my other "true 5s". I put it on my mandrel, and sure enough, the middle of the ring falls on the 5 mark, whereas my tighter rings (which I prefer) have the leading edge falling on the 5 line. So if you consider the leading edge to be the correct size, my ring is about a quarter size too big.
I realise this only applies to quite narrow rings, and this shank is about 2.5 mm. But, do you consider the leading edge to be the correct size, or the middle of the ring falling on the size line of a mandrel? When I asked for size 5, I didn't realise I should have specified "leading edge size 5". It's a little annoying, because with the winter coming and the ring being just slightly large, I think the ring is bound to fall to one side a little. Wondering if I should ask them to do it again when I go home at Christmas, or if it's too small a difference to bother. But in general, I'm quite interested in whether people think the leading edge or the middle of the ring on the mandrel is the "true" size?
